The query to find schools attended by President John F. Kennedy that were founded before 1890 returned no results. This indicates that either the data about the schools he attended or their founding dates is not available in the Freebase knowledge graph, or no such schools exist in the data. Therefore, based on the available data, there are no schools attended by President Kennedy that were founded before 1890.

[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/
rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#

wikibase: <http://wikiba.se/ontology#
qb: <http://purl.org/linked-data/cube#
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] There are many schools named "John F. Kennedy," but none of them have a founding date listed in the data. Since I could not find the schools attended by John F. Kennedy or their founding dates, I will try to find the schools attended by John F. Kennedy using a different approach by searching for educational institutions linked to him through other properties or relations. I will try to find the alma mater or similar properties for John F. Kennedy.

Kennedy was a student by searching for triples with John F. Kennedy as the student in the education schema.

[Tool] Got no rows and 3 columns

[Assistant] I could not find the schools attended by John F. Kennedy or their founding dates in the Freebase knowledge graph. Therefore, I am unable to answer the question "Which schools attended by President Kennedy were founded before 1890?" with the available data.

Feedback (status=retry):
The system's explanation indicates that it could not find the schools attended by John F. Kennedy or their founding dates in Freebase, which led to failure in answering the question. However, the system should attempt to construct a SPARQL query that retrieves the educational institutions attended by John F. Kennedy and their founding dates, if available. This query should use appropriate properties such as 'education' or 'alma mater' to find the schools and 'date founded' or similar properties for the founding dates. Even if the data is incomplete, attempting such a query is necessary to confirm the absence of information. Additionally, the query should return the identifiers of the schools and their founding dates, and filter for those founded before 1890. The system should retry with such a query to either find the answer or definitively conclude that the data is missing.

[Assistant] Thank you for the feedback. I will now construct a SPARQL query that attempts to retrieve the educational institutions attended by John F. Kennedy (fb:m.0d3k14) along with their founding dates, if available. I will use the property fb:people.person.education to find the education records, then get the educational institutions linked to those records, and their founding dates. I will filter the results to only include schools founded before 1890. This query will help confirm whether the data is available or missing.

Feedback (status=done):
The SPARQL query is well-constructed to find schools attended by President John F. Kennedy that were founded before 1890. It correctly uses the education property to find schools and filters by founding date. The query returns no results, which is a valid outcome indicating either no such schools exist in the data or the founding date information is missing. The answer clearly explains this situation. Therefore, the output is correct and complete given the available data.

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 currency is used in the country that speaks Romansh?

[Assistant] The question asks for the currency used in the country where Romansh is spoken. First, I need to identify the country or countries where Romansh is spoken. Then, I will find the currency used in that country. I will start by searching for the entity "Romansh" to identify the language and then find the country associated with it.

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.
