Asking a question is often more important than solving it, because solving a problem may be a mathematical or experimental skill, and asking a new question requires creativity and imagination, and it marks a real advance in science. According to this:. ['Asking questions is harder than solving them.', 'People who are good at asking questions are better at solving problems.', 'Progress in science can only be marked by asking questions.', 'People who lack creative imagination are not good at asking questions.']
