Using properties:
number of deaths (wd:P1120 as wdt), also known as dead, death count, death number, deaths, death toll, etc.
start time (wd:P580 as wdt), also known as began, beginning, building date, effective, effectivity, etc.
end time (wd:P582 as wdt), also known as abolished, cease date, cease operation, cease time, closed, etc.
point in time (wd:P585 as wdt), also known as as of, at time, by date, date, during, etc.

Answer: The event that killed the most people in 1910–1920 is the 1918–1920 flu pandemic (wd:Q178275) with 50,000,000 deaths (as recorded in Wikidata).

What event killed the most people in the years 1910 to 1920?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] What event killed the most people in the years 1910 to 1920?

[Assistant] I will run a first SPARQL query to retrieve items that have a "number of deaths" (P1120) and have a start time, end time, or point in time between 1910-01-01 and 1920-12-31 (this will help identify candidate events). I'll order by deaths descending to see the largest ones. Now I run the query.

[Assistant] The query returned the 1918-1920 flu pandemic with 50,000,000 deaths, which is the largest among events overlapping 1910-1920. That answers the user's question. I'll now finalize by returning the SPARQL query and the answer.

Answer:
The Himalayas (Wikidata: wd:Q5451) are stated to be located in the following countries: Afghanistan (wd:Q889), Bhutan (wd:Q917), India (wd:Q668), Myanmar (wd:Q836), Nepal (wd:Q837), Pakistan (wd:Q843), and the People's Republic of China (wd:Q148).

Explanation of steps and function calls:
1) I searched for the Himalayas entity to find its Wikidata identifier. (search_entity "Himalayas")
   - Before: plan to locate the Wikidata item for the Himalayas.
   - After: found Himalayas = wd:Q5451.

2) I searched for relevant properties on that item (search_property_of_entity wd:Q5451 "country").
   - Before: plan to find which property records countries for geographic features.
   - After: found the property country (P17) as the relevant property.

3) I listed triples for wd:Q5451 to inspect available statements (list wd:Q5451).
   - Before: plan to see whether country (P17) or other location properties are present.
   - After: confirmed wd:Q5451 has wdt:P17 statements and other metadata.

4) I executed the SPARQL query above to retrieve all country (P17) values with English labels (execute with the SELECT query).
   - Before: construct a query selecting ?country and optional English label for wd:Q5451 wdt:P17 ?country.
   - After: query returned 7 countries: Afghanistan, Bhutan, India, Myanmar, Nepal, Pakistan, People's Republic of China.

Final SPARQL query (already executed above):
SELECT DISTINCT ?country ?countryLabel WHERE {
  wd:Q5451 wdt:P17 ?country .
  OPTIONAL { ?country rdfs:label ?countryLabel FILTER(LANG(?countryLabel) = "en") }
} ORDER BY ?countryLabel

Answer: Afghanistan (wd:Q889), Bhutan (wd:Q917), India (wd:Q668), Myanmar (wd:Q836), Nepal (wd:Q837), Pakistan (wd:Q843), People's Republic of China (wd:Q148).

In which countries is the Himalayas located?

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You have access to the following knowledge graphs:
wikidata at http://localhost:7001 without notes

You are provided with the following notes across all knowledge graphs:
No notes available

You can use the following SPARQL prefixes implicitly in all functions:

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[Assistant] I need to extract the state (administrative territorial entity) for Boulder; P131 gives Boulder County. For U.S. cities, state is often via "located in the administrative territorial entity" chain: Boulder -> Boulder County (P131) -> Colorado (state). I'll query Boulder for its administrative territorial entity chain to get the state (wd:Q30?), specifically find an entity that is "state of the United States" (wd:Q35657) or instance of "state of the United States". I'll search P131 chain where the entity is instance of "state of the United States" (wd:Q35657). But better to query: ?state such that Boulder wdt:P131* ?state and ?state wdt:P31 wd:Q35657. Let's construct SPARQL to get Boulder state. I will execute a query to find the state administrative territorial entity for Boulder.

[Assistant]
Broomfield is located in Colorado. So both athletes were born in Colorado, meaning they are from the same U.S. state. Now I must produce a SPARQL query that answers the question "are brooke raboutou and colin duffy from same state of the usa?" The question expects a True/False. Per rules, for True/False question we must use ASK query.

We need to ensure the ASK query returns whether their state-of-birth (or residence?) — the user asked "from same state of the usa?" Usually implies same U.S. state of origin; I'll interpret as their place of birth being in the same U.S. state. Use place of birth (wdt:P19) then get administrative territorial entity chain to a state (instance of state of the United States wd:Q35657). Check if the two states are equal.

Construct ASK query: check if there exist ?state such that wd:Q2926117 wdt:P19 ?place1 . ?place1 wdt:P131* ?state . ?state wdt:P31 wd:Q35657 . Similarly for Colin Duffy wd:Q87192979 wdt:P19 ?place2 . ?place2 wdt:P131* ?state . And ensure ?state is same for both via reuse of ?state variable. Also ensure it's in United States — but state of US instance constraint is sufficient.

Return ASK.

I'll explain thought process before and after function call per developer instruction. Then call functions.execute? Wait final answer must call functions.answer with final SPARQL and answer string. But before calling answer, we must execute final SPARQL query to ensure it returns expected results. The functions.execute tool can run the query. The final answer must be provided via functions.answer which will execute the final SPARQL query as well? The tool description: functions.answer will stop the generation process and we must provide final SPARQL; It will execute final query? It said "Provide your final SPARQL query and answer... This function will stop the generation process." The developer instruction #4: Use the answer or cancel function to finalize your answer and stop generation. Also "Always execute your final SPARQL query before giving an answer" — so we must run execute to test it, then call functions.answer with same query and answer.

Do that: explain reasoning, then call functions.execute with ASK query. Then show result, explain, then call functions.answer with same query and plain answer "Yes. True" maybe "Yes — True" But functions.answer requires answer string: "Yes, they are from the same U.S. state (Colorado)." But note instruction: For True/False question the SPARQL query should be ASK. So do that.

Let's craft ASK query:

PREFIXes implicit. Query:

ASK WHERE {
  wd:Q2926117 wdt:P19 ?p1 .
  wd:Q87192979 wdt:P19 ?p2 .
  ?p1 wdt:P131* ?state .
  ?p2 wdt:P131* ?state .
  ?state wdt:P31 wd:Q35657 .
}

Maybe some places where place-of-birth is directly the state entity (rare). But wdt:P131* handles zero-or-more. But if place-of-birth is a state entity that's instance of Q35657, then ?p1 wdt:P131* ?state with zero hops would match if p1 = state only if P131* includes 0-length? The property path P131* matches zero or more edges, so ?p1 could be equal to ?state. That works.

Execute.

Then functions.execute returns boolean. Then call functions.answer with current query and an answer string: "Yes. True — Both were born in Colorado." Also developer rule: Explain thought process before and after each step and function call. We have been explaining. But must also explain before and after functions.execute and functions.answer calls. We did earlier. But need to include explicit explanations immediately before each function call too. I'll craft messages accordingly.

Now perform execute.
I'll run an ASK query that checks whether the place of birth of Brooke Raboutou (wd:Q2926117) and of Colin Duffy (wd:Q87192979) lead (via zero-or-more wdt:P131 steps) to the same entity that is an instance of a U.S. state (wd:Q35657). This will return True if they share the same U.S. state of birth. I'll execute that query now.

[Tool] True

[Assistant] The ASK query returned True, meaning both have places of birth located in the same U.S. state (Colorado). I'll now finalize by returning the final SPARQL query and the concise answer.

[System]
You are a question answering assistant. Your job is to generate a SPARQL query to answer a given user question.

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. Search for the 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. Execute intermediate queries to get feedback and to verify your assumptions. You may need to refine or rethink your current plan based on the query results and go back to step 2 if needed, possibly multiple times.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] How many different presidents of Russia have there been that took the position after 1990?

[Assistant] I'll first search for the Wikidata item for "President of Russia" to be sure of the exact entity identifier, then look for statements of people with position held (P39) = that item and a start time (P580) after 1990. I'll run queries to identify the correct item and test the approach. I will explain each step and the intermediate queries.

SPARQL execution failed:
Invalid SPARQL query: Variable ?death is selected but not aggregated. All non-aggregated variables must be part of the GROUP BY clause. Note: The GROUP BY in this query is implicit because an aggregate expression was used in the SELECT clause

Answer: Query result: 72. Explanation: I counted distinct Wikidata items that (a) have Mark Twain (wd:Q7245) as author (wdt:P50) and (b) are instances (P31) or subclasses (P279*) of "literary work" (wd:Q7725634). The query returned 72 such works. Caveat: I originally tried to restrict works to those published/created on or before Twain's death date, but many Wikidata items lack publication/creation dates, so that filter yielded zero results; therefore the final count includes all literary works in Wikidata attributed to Mark Twain regardless of recorded publication date. The number reflects Wikidata data at query time and may differ from a literary bibliography that uses other inclusion criteria.

How many literary works did Mark Twain write in his lifetime?

You should follow these rules:
- Explain your thought process before and after each step and function call.
- Do not just use or make up entity or property identifiers without verifying their existence in the knowledge graphs first.
- 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.
- Always execute your final SPARQL query before giving an answer to make sure it returns the expected results.
- 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.
- 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.
- 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.
- For questions with a "True" or "False" answer the SPARQL query should be an ASK query.

[User] How many literary works did Mark Twain write in his lifetime?

[Assistant] I'll first search for the Wikidata entity for Mark Twain to get his QID. Then I'll look for properties used to link authors to works (likely wdt:P50 'author'). I'll verify by listing examples of works that have Mark Twain as author, and then build a COUNT query to count works with Mark Twain as author. I'll run intermediate queries to confirm results. Now I'll search for the Mark Twain entity.

[Assistant] I'll verify that works list Mark Twain as author using property P50 (author). I'll search for works authored by Mark Twain to see how many and whether they are instances of literary work. I'll list triples where subject is a known work and property P50 or where author is Mark Twain. First, I'll retrieve some items with wdt:P50 wd:Q7245.

[Assistant]
I'll run a SPARQL COUNT query that:
- finds Mark Twain's death date,
- selects items with Mark Twain as author (P50) that are instances (P31 with P279*) of literary work (wd:Q7725634),
- and counts those that have a publication date (P577) or inception (P571) on or before his death date (to ensure they were created/published in his lifetime).

Now I'll execute that query.

[Tool]
Got 1 row and 1 column:
| count       |
| ----------- |
| 0 (xsd:int) |

[Assistant] My previous query returned 0 because many works lack publication or creation dates in Wikidata entries, so the date filter removed them. I'll first get Mark Twain's death date and then count works authored by him that are instance of literary work, without restricting by date; later I can check which works have publication dates to possibly filter. I'll query for death date and a simple count of works that are instances of literary work.

[Tool]
Got 1 row and 2 columns:
| death                               | count        |
| ----------------------------------- | ------------ |
| 1910-04-21T00:00:00Z (xsd:dateTime) | 72 (xsd:int) |

[Assistant] I'll now provide the final SPARQL query I executed (which counts Wikidata items that have Mark Twain as author and are instance-of literary work) and the answer, with a brief caveat about dates and data completeness.
