Is there only one answer to a question?

A question may be either an expression used to make a request for information, or else the request itself made by such an expression. Not all questions have answers . While some questions have concrete, verifiable answers. (e.g: Is the sun hot?), some do not. eg) Did Julius ceaser like his eggs scrambled, boiled or sunny-side up? Any answer to this question, would not be an answer per se, but an assumed, unverifiable answer, meaning it is not an answer at all but just an opinion being voiced, therefore the question asked, although answered, is not answered. So conclusively, any answer given to said question will not answer the question therefore the question will remain un-answerable although answers might be given. so to answer your question, Opinions can and always will be given to any question asked, however, they might not always qualify as answers.
