You will be given a context, a subject and a relation. Your task is to generate a question based on the subject and relation. The generated question should include the given subject. Try to use a minimum number of words that are not present in either context, subject or relation while generating question.

Let me give you an example: Context : Isaac Nicola Romero (1916 in Havana, Cuba -- 1997) was a prominent Cuban guitarist and one of the founders of the modern Cuban Guitar School. 
Subject : Isaac Nicola 
Relation : place of birth
The answer to this example can be: What was Isaac Nicola's city of birth?
Here is why: Here the question is generated on Isaac Nicola Romero who is the subject and the relation of question to the context is about the place of birth of Isaac Nicola Romero. Hence generated question is correct

OK. solve this:
Context : Brad Whitaker is a fictional character in the James Bond film The Living Daylights.
