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

You have access to the following knowledge graphs:
freebase at https://qlever.cs.uni-freiburg.de/api/freebase

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

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] What type of political system does the government that held the 54th Brazilian National Congress have?

[Assistant]
To answer this question, we need to identify the following:

1. The 54th Brazilian National Congress.
2. The government that was in power during the 54th Brazilian National Congress.
3. The type of political system of that government.

Let's start by searching for the 54th Brazilian National Congress in Freebase.

[Assistant]
None of the properties listed directly indicate the type of political system. However, the "Jurisdiction" property (fb:government.governmental_body.jurisdiction) might provide some context about the country and potentially help us infer the political system.

Let's execute a SPARQL query to find the jurisdiction of the National Congress of Brazil.

```sparql
SELECT ?jurisdiction
WHERE {
  fb:m.033176 fb:government.governmental_body.jurisdiction ?jurisdiction .
}
```

Let's run this query.

[Tool]

[Assistant]
The property "Form of Government" (fb:location.country.form_of_government) seems to be the most relevant for determining the type of political system in Brazil. Let's execute a SPARQL query to find the form of government of Brazil.

```sparql
SELECT ?formOfGovernment
WHERE {
  fb:m.015fr fb:location.country.form_of_government ?formOfGovernment .
}
```

Let's run this query.

[Tool]

| Presidential system (fb:m.01d9r3)     |
| Constitutional republic (fb:m.0c9rw5) |
| Federal republic (fb:m.0j729)         |

[Assistant]
The form of government in Brazil includes a presidential system, a constitutional republic, and a federal republic. These terms collectively describe the type of political system in Brazil.

Therefore, the type of political system of the government that held the 54th Brazilian National Congress is a presidential, constitutional, and federal republic.

Here is the final SPARQL query and answer:

```sparql
SELECT ?formOfGovernment
WHERE {
  fb:m.015fr fb:location.country.form_of_government ?formOfGovernment .
}
```

Answer: The type of political system of the government that held the 54th Brazilian National Congress is a presidential, constitutional, and federal republic.

[User] What university with 30477 undergraduates did J.R.R. Tolkien attend?

[Assistant]
To answer this question, we need to identify the following elements:

1. The entity representing J.R.R. Tolkien.
2. The property that indicates the university he attended.
3. The property that indicates the number of undergraduate students at a university.
4. The specific university that matches the criteria of having 30477 undergraduates.

Let's start by searching for the entity representing J.R.R. Tolkien.

[Tool]
Top 10 entity alternatives:
1. J. R. R. Tolkien, also known as Tolkien, J.R.R., Tolkien, JRR Tolkien, John Ronald Reuel Tolkien, CBE, John Ronald Reuel Tolkien, Beren (fb:m.041h0): John Ronald Reuel Tolkien, CBE FRSL was an English writer, poet,...plied the term legendarium to the larger part of these writings., Author
2. J. R. R. Tolkien: Author of the Century, also known as J.R.R. Tolkien (fb:m.02z0m1n): J.R.R. Tolkien: Author of the Century is a work of literary crit...oday and attempts to firmly establish Tolkien's literary merits., Book

9. J.R.R. Tolkien (fb:m.0c6dx2n): Book Edition
10. J.R.R. Tolkien (fb:m.05q79m8): Book Edition

[Assistant] The top result for J.R.R. Tolkien is `fb:m.041h0`, which seems to be the correct entity representing the author. Next, we need to find the property that indicates the university he attended. Let's search for properties related to education or alma mater for this entity.

[Tool]
Top 10 property alternatives:
1. Country of nationality (fb:people.person.nationality): Country, Person
2. Place of birth (fb:people.person.place_of_birth): Location, Person
3. Education (fb:people.person.education): Education, Person
4. Profession (fb:people.person.profession): Profession, Person

10. Places lived (fb:people.person.places_lived): Place lived, Person

No other items found

[Assistant]
The property `fb:people.person.education` seems to be the most relevant for indicating the university J.R.R. Tolkien attended. Now, let's find out which university he attended by querying this property.

Next, we need to find the property that indicates the number of undergraduate students at a university. Let's search for this property.

[Tool]
Top 10 property alternatives:
1. Number of undergraduates (fb:base.yalebase.residential_college.number_of_undergraduates): Residential college, Integer
2. Number of undergraduates (fb:education.university.number_of_undergraduates): College/University, Dated Integer
3. Students (fb:user.robertm.default_domain.professor.students): Professor, Teaching

9. Number of faculty (fb:education.educational_institution.faculty): Educational Institution, Dated Integer
10. Student(s) (fb:user.ddammann.default_domain.teacher.students): Teacher, Student

[Assistant]
The property `fb:education.university.number_of_undergraduates` seems to be the most relevant for indicating the number of undergraduate students at a university.

Now, let's combine these pieces of information to find the university that J.R.R. Tolkien attended and has 30477 undergraduates. We will first find the university J.R.R. Tolkien attended and then check if it has the specified number of undergraduates.

Let's start by finding the university J.R.R. Tolkien attended.

| ------------ |
| fb:m.02wmyw7 |
| fb:m.0n1m7cd |
| fb:m.0w48bvz |
| fb:m.0w48bx3 |

[Assistant] J.R.R. Tolkien attended multiple institutions, and we have four potential universities: `fb:m.02wmyw7`, `fb:m.0n1m7cd`, `fb:m.0w48bvz`, and `fb:m.0w48bx3`. Next, we need to check which of these universities has 30477 undergraduate students. Let's query the number of undergraduate students for each of these universities.

[Tool] Got no rows and 2 columns

[Assistant]
It appears that none of the universities J.R.R. Tolkien attended have the property `fb:education.university.number_of_undergraduates` with the value 30477. This suggests that either the data is incomplete or the specific number of 30477 undergraduates is not recorded in Freebase for these universities.

Given this, we need to verify the universities and their details more closely. Let's try to get the labels of these universities to see if we can identify them and cross-check the information manually.

Let's fetch the labels of the universities.

[Tool] Got no rows and 2 columns

[Assistant]
It seems that the labels for these universities are not available in Freebase. This makes it difficult to identify the specific universities J.R.R. Tolkien attended and verify the number of undergraduate students.

Given the lack of detailed information in Freebase, we may not be able to definitively answer the question with the current data. However, we can still provide the best attempt at a SPARQL query that would answer the question if the data were available.

Here is the SPARQL query that would answer the question if the data were complete:

```sparql
SELECT ?university ?label WHERE {
  fb:m.041h0 fb:people.person.education ?university .
  ?university fb:education.university.number_of_undergraduates 30477 .
  ?university rdfs:label ?label .
}
```

Since we cannot find the specific university with 30477 undergraduates in Freebase, I will provide this query as the best attempt and explain the limitations.
