Questions are for asking. But what is the meaning of this world which carries a lot of question marks. A question may be what, when, who, where, why, how, whom and the solutions may vary depending upon the question.
Question is not only about all of these words, but it can be you, me or all. I am also a question, similarly you and whole of the world is.
No doubt, there is not a solution present to each question. Sometimes, questions have an answer while sometimes, they are unanswerable.
