The query lists all championship events won by Arsenal F.C. (including league and cup wins). You can identify the league wins (such as Premier League or First Division titles) from the returned events and their labels.

[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:
fb: <http://rdf.freebase.com/ns/
fbkey: <http://rdf.freebase.com/key/

void: <http://rdfs.org/ns/void#

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]
The similar examples show that to answer "when did [team] win the league/championship?", we need to:

1. Identify the entity for Arsenal (the football club).
2. Use the property fb:sports.sports_team.championships to get the championships Arsenal has won.
3. From the championship events, extract the years or dates.

Let's proceed step by step:

Step 1: Find the Freebase entity for Arsenal (the football club).

[Assistant]
The property fb:sports.sports_team.championships is used for championships won by the team. This matches the pattern from the similar examples.

Now, let's list the values for fb:sports.sports_team.championships for Arsenal (fb:m.0xbm) to see what information is available about their league wins.

[Assistant]
The results show that Arsenal's "championships" property includes many FA Cup wins, but the user is specifically asking about league wins (i.e., when Arsenal won the English top division, now known as the Premier League).

To refine the answer, I need to:
- Identify which of these championships are league titles, not cup wins.
- Check if the championship event entity has a property indicating the type of competition (league vs. cup).

Let's inspect one of these championship event entities (e.g., fb:m.0vptrcs for "2013–14 FA Cup") to see what properties are available and how to distinguish league wins.

The query filtered for championship events won by Arsenal with "league" in the label, but the results are "Football League Cup" wins, not league titles. The Football League Cup is a knockout competition, not the league championship.

To accurately answer "when did Arsenal win the league?", I need to:
- Find all championship events won by Arsenal.
- For each event, check if its label or description indicates it is a "Premier League" or "First Division" title (the English top division).

Let's expand the query to get all championship events won by Arsenal, along with their labels, and then filter for those that are league titles.

It appears that the Freebase data for Arsenal's league wins is not easily distinguishable from their cup wins using the available labels and descriptions. The championship events won by Arsenal are mostly labeled as "FA Cup" or other competitions, and attempts to filter for "Premier League" or "First Division" in the labels or descriptions did not yield relevant results.

Given this, the best possible SPARQL query to answer "when did Arsenal win the league?" in Freebase is to list all championship events won by Arsenal, and the user can manually identify the league wins from the list.

Here is the query that lists all championship events won by Arsenal, with their identifiers and optional labels:

SELECT DISTINCT ?event ?label WHERE {
  ?event fb:sports.sports_championship_event.champion fb:m.0xbm .
  OPTIONAL { ?event rdfs:label ?label }
}
```

This will return all championship events (including league and cup wins) won by Arsenal, and the user can look for league titles among them.

void: <http://rdfs.org/ns/void#

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.

Spouse (or domestic partner) (fb:people.person.spouse_s): links to type Marriage, part of Person schema

Example 3:
Question:
who is angelina jolie's husband?

SPARQL:
SELECT DISTINCT ?x WHERE {
  FILTER ( ?x != fb:m.0f4vbz ) FILTER ( ! isLiteral( ?x ) || lang( ?x ) = '' || langMatches( lang( ?x ) , 'en' ) ) fb:m.0f4vbz fb:people.person.spouse_s ?y .

Type of union (fb:people.marriage.type_of_union): links to type Marriage/union type, part of Marriage schema
Spouse (or domestic partner) (fb:people.person.spouse_s): links to type Marriage, part of Person schema

[Assistant]
From the similar examples, I see that:

- Esther's Freebase entity is likely fb:m.02pn7.
- To find a person's spouse, the property fb:people.person.spouse_s links to a Marriage entity, and then fb:people.marriage.spouse links to the spouse (person).

So, the pattern is:
1. Get the Marriage entity via fb:people.person.spouse_s from Esther.
2. Get the spouse via fb:people.marriage.spouse from the Marriage entity.

Let's verify that fb:m.02pn7 is indeed Esther by searching for "Esther" in Freebase.

[Assistant]
The similar examples show a clear pattern for answering this question in Freebase:

1. Identify the entity for Spencer Pratt (fb:m.02z3d24).
2. Use the property fb:people.person.education to get the education nodes.
3. From those, use fb:education.education.institution to get the school(s).

The query should select the institution IRIs, and optionally their labels.

I will now write the SPARQL query accordingly.
