The simple answer is for seeking information.Right questions brings right information while an ambiguous questions gives incomplete or wrong information.So there must be right question on a topic on issue at an appropriate time.
For example If an aspirant asks a question on the introductory part of the new foreign policy of the Government of India from a professor who is about to complete the lecture on the topic,most likely the professor would not answer it properly due to wrong timing of raising the question.But if he asks the same question from the same professor after he finishes the lecture,perhaps he would welcome the idea,giving him a detailed insight on the topic.So,it is absurd to ask questions on the introductory part about the topic which is reaching conclusion.In case a district magistrate gets a complaint against a block employee,will he suspend that employee on the basis of complaint only?Never,before doing so,he would probe the matter.To investigate the issue,he would seek information by questioning the employee and other sources.Having received complete information,he will think of final action.
So,by raising right questions in particular situation is an important part and you will gather better information,build stronger relationships,manage people more effectively and help others to learn,too.
