1. A question generation apparatus comprising:
at least one processor, the at least one processor carrying out:
an acquiring process of acquiring a plurality of character strings each of which can be an answer to a question and pieces of text respectively associated with the plurality of character strings, the question having one or more answers, wherein the corresponding one of the plurality of character strings is included in the one or more answers;
a question generating process of generating, with reference to the pieces of text, a question for each of the plurality of character strings, the question having one or more answers, wherein each of the plurality of character strings is included in the one or more answers;
an ambiguity judging process for each question generated in the question generating process, of determining whether the one or more answers include another one of the plurality of character strings in addition to the corresponding character string, the determining comprising calculating a cosine similarity between vector embeddings of respective answers and judging the question as ambiguous when the cosine similarity is equal to or greater than a predetermined similarity threshold; and
an outputting process of outputting a question which is included in the plurality of questions generated in the question generating process and which has been judged, in the ambiguity judging process, to be the question to which there are a plurality of answers.
