You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] Give me all communist countries.

[Assistant] To find all communist countries, we need to identify the property that indicates a country's government type and then look for the specific value that represents communism. Let's start by searching for the property that might indicate the government type of a country.

[Tool]
Top 10 property alternatives:
1. basic form of government, also known as form of government, government, type of government (wd:P122 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): subject's government
2. head of government, also known as head of national government, mayor, premier, president, prime minister (wd:P6 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): head of the executive power of this town, city, municipality, state, country, or other governmental body, director / manager, chairperson

7. legislative body, also known as aboriginal council, Zila, Tehsil, rural council, representative body (wd:P194 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): legislative body governing this entity; political institution wi...ted representatives, such as a parliament/legislature or council
8. position holder, also known as incumbent, noble title holder, office holder, position held by (wd:P1308 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): persons who hold and/or held the position

[Assistant] From the search results, the property `P122` (form of government) seems to be the most relevant for our purpose. Now, let's search for the entity that represents communism as a form of government.

[Tool]
Top 10 entity alternatives:
1. communism (wd:Q6186): far-left political and socioeconomic ideology
2. Kommunizm, also known as Communism (wd:Q17617682): village in Alay District, Osh Province, Kyrgyzstan
3. Kommunizm, also known as Communism (wd:Q12825065): village in Kara-Suu District, Osh Province, Kyrgyzstan
4. Kommunizm, also known as Communism (wd:Q12825063): village in Nookat District, Osh Province, Kyrgyzstan

9. communism (wd:L673648-S1)
10. communism (wd:L1008056-S1)

[Assistant]
The entity `wd:Q6186` (communism) appears to be the correct representation of communism as a political and socioeconomic ideology. Now, we can construct a SPARQL query to find all countries that have communism as their form of government.

Let's write and execute the SPARQL query to find all countries with communism as their form of government.

```sparql
SELECT ?country ?countryLabel
WHERE {
  ?country wdt:P122 wd:Q6186 .
  OPTIONAL { ?country rdfs:label ?countryLabel . FILTER(LANG(?countryLabel) = "en") }
}
```

This query selects all countries (`?country`) that have the form of government (`wdt:P122`) set to communism (`wd:Q6186`). It also optionally retrieves the English label of the country for better readability.

Let's execute this query.

[Tool]
Got 2 rows and 2 columns:
| ?country                   | ?countryLabel |
| -------------------------- | ------------- |
| Orderrealm (wd:Q123126969) | Orderrealm    |
| Borduria (wd:Q1751472)     | Borduria      |

[Assistant]
The query returned two results, but both seem to be fictional or less well-known entities rather than widely recognized communist countries. This suggests that the form of government property (`P122`) might not be the best way to identify communist countries.

Let's try another approach. We can look for countries where the ruling party is a communist party. To do this, we need to find the property that indicates the ruling party of a country and then look for the specific value that represents a communist party.

First, let's search for the property that indicates the ruling party of a country.

[Tool]
Top 10 property alternatives:
1. member of political party, also known as political party member, political party, party membership, party, member of party (wd:P102 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): the political party of which a person is or has been a member or otherwise affiliated, member of
2. political coalition, also known as electoral block, political bloc, political alliance, electoral list, electoral alliance (wd:P5832 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): agreement for cooperation between different political parties, member of
3. head of government, also known as head of national government, mayor, premier, president, prime minister (wd:P6 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): head of the executive power of this town, city, municipality, state, country, or other governmental body, director / manager, chairperson
4. political alignment, also known as political position, alignment (wd:P1387 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): political position within the left–right political spectrum

6. parliamentary group, also known as faction, party organization, party (wd:P4100 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): parliamentary group to which a member of a parliament belongs, member of
7. political ideology, also known as editorial viewpoint, has political ideology, ideology, official ideology, official political ideology (wd:P1142 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): political ideology of an organization or person or of a work (such as a newspaper)
8. office held by head of government, also known as title of head of government, position of head of government, office of head of government, head of government's office, position held by head of government (wd:P1313 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): political office that is fulfilled by the head of the government of this item

[Assistant]
From the search results, the property `P102` (member of political party) seems to be the most relevant for identifying the ruling party of a country. However, this property is typically used for individuals rather than countries. Instead, we should look for a property that directly indicates the ruling party of a country.

Let's search for the property that indicates the ruling party of a country again, but this time with a more specific query to ensure we find the right property.

[Tool]
Top 10 property alternatives:
1. member of political party, also known as political party member, political party, party membership, party, member of party (wd:P102 as psv/pqn/prn/pr/wdtn/p/pqv/prv/pq/wdt/ps/psn): the political party of which a person is or has been a member or otherwise affiliated, member of

[Assistant]
It seems that the property `P102` (member of political party) is still the closest match, but it is primarily used for individuals. There doesn't appear to be a direct property for the ruling party of a country. However, we can infer the ruling party by looking at the head of government or head of state and their political party.

Let's use the property `P6` (head of government) and `P102` (member of political party) to find countries where the head of government is a member of a communist party.

First, we need to find the entity for the Communist Party. Let's search for it.

[Tool]
Top 10 entity alternatives:
1. communist party (wd:Q233591): political party that promotes communist philosophy and values
2. Communist Party, also known as K, KFML(r), Kommunistiska Partiet, KP, KPML(r) (wd:Q965481): political party in Sweden
3. Communist Party of Britain, also known as British Communist Party, CPB, Communist Party (wd:Q1120576): British political party

5. Communist Party (wd:Q5154557): Italian political party
6. Communist Party (wd:Q2883859): political party in Flanders, Belgium
7. Communist Party, also known as Red Flag Communist Party, Red flags, RFCP (wd:Q5154315): former political party in Burma (Myanmar)
8. Communist Party (wd:Q18150101): political party in Turkey
9. Communist Party, also known as KPD (wd:Q5154316): political party in the Free City of Danzig
10. Communist Party, also known as PCN (wd:Q1284593): defunct political party in Romania

[Assistant]
The entity `wd:Q233591` (communist party) appears to be the most general and appropriate representation of a communist party. Now, we can construct a SPARQL query to find all countries where the head of government is a member of a communist party.

Here is the SPARQL query:

```sparql
SELECT ?country ?countryLabel
WHERE {
  ?country wdt:P6 ?headOfGovernment .
  ?headOfGovernment wdt:P102 wd:Q233591 .
  OPTIONAL { ?country rdfs:label ?countryLabel . FILTER(LANG(?countryLabel) = "en") }
}
```

This query selects all countries (`?country`) where the head of government (`?headOfGovernment`) is a member of a communist party (`wd:Q233591`). It also optionally retrieves the English label of the country for better readability.

Let's execute this query.

[Tool] Got no rows and 2 columns

[Assistant]
The query did not return any results, which suggests that either the data is not available in the knowledge graph, or the approach needs further refinement.

Another approach could be to look for countries where the ruling party is a communist party, even if the head of government is not explicitly listed as a member. We can use the property `P35` (head of state) and check if the head of state is a member of a communist party, or we can look for the ruling party directly.

Let's try using the property `P35` (head of state) and see if we can find any countries where the head of state is a member of a communist party.

Here is the updated SPARQL query:

```sparql
SELECT ?country ?countryLabel
WHERE {
  ?country wdt:P35 ?headOfState .
  ?headOfState wdt:P102 wd:Q233591 .
  OPTIONAL { ?country rdfs:label ?countryLabel . FILTER(LANG(?countryLabel) = "en") }
}
```

This query selects all countries (`?country`) where the head of state (`?headOfState`) is a member of a communist party (`wd:Q233591`). It also optionally retrieves the English label of the country for better readability.

Let's execute this query.

[Tool] Got no rows and 2 columns

[Assistant]
The query using the head of state also did not return any results. This suggests that the data might not be structured in a way that directly links the head of state or head of government to the communist party.

Given the lack of direct links, we can try a different approach by looking for countries where the ruling party is explicitly labeled as a communist party. We can use the property `P122` (form of government) and look for countries where the government is described as a one-party communist state.

Let's search for the entity that represents a one-party communist state.

[Tool]
Top 10 entity alternatives:
1. single-party system, also known as single-party country, one-party state, one-party system (wd:Q50686): political system with only one party permanently in control
2. communist state, also known as Marxist-Leninist state, communist country (wd:Q849866): state that is administered and governed by a single communist party
3. dominant-party system, also known as one-party dominant state (wd:Q2439061): continuous dominance of a single political party in elections
4. fictional communist state, also known as fictional communist country (wd:Q82519323): communist state which only exists in a work of fiction

8. Science in Communist States (wd:Q59086620): scientific article published in Nature
9. Communist states and post-war Africa (wd:Q128949234): scholarly article
10. Communist Party of the United States of America, also known as Communist Party of the U.S.A., Communist Party USA, CPUSA, Communist Party of the United States (wd:Q308714): American political party

[Assistant]
The entity `wd:Q849866` (communist state) appears to be the most relevant representation of a one-party communist state. Now, we can construct a SPARQL query to find all countries that are described as communist states.

Here is the SPARQL query:

```sparql
SELECT ?country ?countryLabel
WHERE {
  ?country wdt:P122 wd:Q849866 .
  OPTIONAL { ?country rdfs:label ?countryLabel . FILTER(LANG(?countryLabel) = "en") }
}
```

This query selects all countries (`?country`) that have the form of government (`wdt:P122`) set to a communist state (`wd:Q849866`). It also optionally retrieves the English label of the country for better readability.

Let's execute this query.

[Tool]
Got 2 rows and 2 columns:
| ?country                                 | ?countryLabel               |
| ---------------------------------------- | --------------------------- |
| Somali Democratic Republic (wd:Q1477220) | Somali Democratic Republic  |
| Finnish Democratic Republic (wd:Q62519)  | Finnish Democratic Republic |

[Assistant]
The query returned two results, but both are historical states that no longer exist. This suggests that the form of government property (`P122`) might not be the best way to identify current communist countries.

Given the challenges with the current approach, let's try a different strategy. We can look for countries where the ruling party is explicitly labeled as a communist party. We can use the property `P122` (form of government) and look for countries where the government is described as a one-party communist state, but this time, we will also check for the ruling party directly.

Let's search for the property that indicates the ruling party of a country again, but this time, we will use a more specific query to ensure we find the right property.

Since the previous approaches did not yield the expected results, let's try a more direct approach by looking for countries where the government is explicitly labeled as a communist state or where the ruling party is a communist party.

We can use the property `P122` (form of government) and look for countries where the government is described as a one-party communist state. Additionally, we can look for countries where the ruling party is a communist party.

Let's combine these approaches in a single query:

```sparql
SELECT DISTINCT ?country ?countryLabel
WHERE {
  {
    ?country wdt:P122 wd:Q849866 .
  } UNION {
    ?country wdt:P35 ?headOfState .
    ?headOfState wdt:P102 wd:Q233591 .
  } UNION {
    ?country wdt:P6 ?headOfGovernment .
    ?headOfGovernment wdt:P102 wd:Q233591 .
  }
  OPTIONAL { ?country rdfs:label ?countryLabel . FILTER(LANG(?countryLabel) = "en") }
}
```

This query combines three approaches:
1. Countries where the form of government is a one-party communist state (`wd:Q849866`).
2. Countries where the head of state is a member of a communist party (`wd:Q233591`).
3. Countries where the head of government is a member of a communist party (`wd:Q233591`).

Let's execute this query.

[Assistant]
The query still returned only historical states that no longer exist. This suggests that the data in Wikidata might not be comprehensive or up-to-date for current communist countries.

Given the challenges, let's take a different approach by manually identifying some known current communist countries and checking if they are correctly represented in Wikidata. We can then use these known entities to refine our query.

Some known current communist countries include:
- Cuba
- China
- Vietnam
- North Korea
- Laos

Let's search for these countries and check their properties to see if they are correctly labeled as communist states or if their ruling parties are communist parties.

First, let's search for these countries.

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[Assistant]
From the search results, the property `wd:P177` (crosses) seems to be the most relevant for indicating the river that the Brooklyn Bridge crosses. Let's construct a simple SPARQL query to find the river that the Brooklyn Bridge crosses using this property.

We will start with a basic query and then refine it if necessary.

```sparql
SELECT ?river WHERE {
  wd:Q125006 wdt:P177 ?river .
}
```

Let's execute this query to see the results.

[Tool]
Got 1 row and 1 column:
| ?river                  |
| ----------------------- |
| East River (wd:Q212862) |

[Assistant]
The query returned the East River as the river that the Brooklyn Bridge crosses. To provide a more complete answer, we can include the label of the river in the result. However, since the user did not explicitly request the label, we will keep the query simple and return the IRI of the river.

Here is the final SPARQL query:

```sparql
SELECT ?river WHERE {
  wd:Q125006 wdt:P177 ?river .
}
```

The answer to the question is that the Brooklyn Bridge crosses the East River.

Now, let's finalize the answer.

To answer the question about which mountain is the highest after Annapurna, we need to follow these steps:

1. Identify the entity for Annapurna.
2. Find the property for height.
3. List mountains and their heights.
4. Filter out Annapurna and sort the remaining mountains by height in descending order.
5. Select the top result.

Let's start by identifying the entity for Annapurna.

[Tool]
Top 10 entity alternatives:
1. Annapurna, also known as Annapurna Himal, Annapurna (Himalayas), Annapurna Massif (wd:Q159621): mountain range in the Himalayas

[Assistant]
The most relevant property for height is `wd:P2048` (height).

Now, let's list mountains and their heights, filter out Annapurna, and sort the remaining mountains by height in descending order. We will then select the top result.

Let's start with a simple query to list mountains and their heights.

[Tool]
Got 10 rows and 2 columns:

| Mount Amanokagu (wd:Q11443780)             | 152     |

[Assistant]
The initial query returned some mountains and their heights, but it seems to include smaller mountains and hills. To focus on major mountains, especially those in the Himalayas, we need to filter the results to include only significant peaks.

Let's refine the query to include only mountains that are part of the Himalayas and have a height greater than 7000 meters. We will also exclude Annapurna and sort the results by height in descending order.

[Tool] Got no rows and 2 columns

[Assistant]
It seems that the query did not return any results, possibly because the constraints were too strict. Let's try a more relaxed approach by removing the country constraint (`wdt:P17 wd:Q39`) and focusing on the Himalayan range (`wdt:P361 wd:Q503`). We will also lower the height threshold slightly to ensure we get more results.

Let's adjust the query accordingly.

[Tool] Got no rows and 2 columns

[Assistant]
It appears that even with the relaxed constraints, the query is still not returning any results. This might be due to the specific constraints on the Himalayan range and the height threshold.

Let's try a different approach by listing all mountains with a height greater than 7000 meters and then manually exclude Annapurna and sort the results. This will help us identify if there are any issues with the constraints.

Let's execute this query:

[Tool] Got no rows and 2 columns

[Assistant]
It seems that even without the specific constraints on the Himalayan range, the query is still not returning any results. This suggests that there might be an issue with the height property or the way we are querying the data.

Let's try a different approach by listing all mountains and their heights without any filters, and then we can manually inspect the results to see if we can identify the issue.

[Assistant]
The query returned a list of mountains and their heights, but the heights seem to be incorrect or not in the expected range. For example, Mauna Kea is listed with a height of 32,000 meters, which is not accurate. This suggests that the property `wd:P2048` might not be the correct property for the height of mountains.

Let's try using the property `wd:P2044` (elevation above sea level) instead, which is more commonly used for the height of geographical features.

Let's adjust the query to use `wd:P2044` and filter out Annapurna, then sort the results by height in descending order.

[Tool]
Got 10 rows and 2 columns:
| ?mountain                     | ?height |

[Assistant]
The query using the property `wd:P2044` (elevation above sea level) returned a list of mountains and their heights, but the heights are still not in the expected range for major Himalayan peaks. This suggests that the data might not be accurate or complete for these specific mountains.

To find the highest mountain after Annapurna, we need to focus on the Himalayan range and ensure we are looking at the correct peaks. Let's try a more targeted approach by specifically searching for major peaks in the Himalayas and excluding Annapurna.

We will use the property `wd:P361` to filter for mountains that are part of the Himalayas and then sort by height.

Let's execute this query:

[Tool] Got no rows and 2 columns

[Assistant]
It seems that even with the targeted approach, the query is still not returning any results. This suggests that the data for major Himalayan peaks might be incomplete or not structured in the way we expect.

Let's try a different approach by manually identifying the major peaks in the Himalayas and then comparing their heights. We can use the known peaks such as Mount Everest, K2, Kangchenjunga, Lhotse, Makalu, Cho Oyu, Dhaulagiri, Manaslu, and Nanga Parbat.

Let's search for these peaks and their heights, and then exclude Annapurna to find the highest peak after it.

First, let's search for the entities of these peaks.

Now that we have the entities for the major peaks in the Himalayas, let's write a SPARQL query to get their heights and exclude Annapurna. We will then sort the results by height in descending order to find the highest mountain after Annapurna.

Here is the SPARQL query:

```sparql
SELECT ?mountain ?height WHERE {
  VALUES ?mountain { wd:Q513 wd:Q43512 wd:Q82019 wd:Q168702 wd:Q169986 wd:Q170089 wd:Q165440 wd:Q170070 wd:Q130736 }
  ?mountain wdt:P2044 ?height .
  FILTER(?mountain != wd:Q159621)
} ORDER BY DESC(?height) LIMIT 10
```

Let's execute this query.

[Tool]
Got 9 rows and 2 columns:
| ?mountain                 | ?height |
| ------------------------- | ------- |
| Mount Everest (wd:Q513)   | 8848.86 |
| K2 (wd:Q43512)            | 8611    |
| Kanchenjunga (wd:Q82019)  | 8586    |
| Lhotse (wd:Q168702)       | 8516    |
| Makalu (wd:Q169986)       | 8485    |
| Cho Oyu (wd:Q170089)      | 8188    |
| Dhaulagiri (wd:Q165440)   | 8167    |
| Manaslu (wd:Q170070)      | 8163    |
| Nanga Parbat (wd:Q130736) | 8126    |

[Assistant]
The query returned the heights of the major peaks in the Himalayas, excluding Annapurna. The highest mountain after Annapurna is Nanga Parbat, with a height of 8,126 meters.

Therefore, the answer to the question "Which mountain is the highest after the Annapurna?" is Nanga Parbat.

Here is the final SPARQL query and answer:

```sparql
SELECT ?mountain ?height WHERE {
  VALUES ?mountain { wd:Q513 wd:Q43512 wd:Q82019 wd:Q168702 wd:Q169986 wd:Q170089 wd:Q165440 wd:Q170070 wd:Q130736 }
  ?mountain wdt:P2044 ?height .
  FILTER(?mountain != wd:Q159621)
} ORDER BY DESC(?height) LIMIT 10

You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] How many people live in the capital of Australia?

[Assistant] To answer the question "How many people live in the capital of Australia?", we need to identify the capital of Australia and then find the population of that city. Let's start by identifying the capital of Australia.
