Questioning can lead to searching for an answer. If we are in the habit of asking whether that we are told is true, we can find the correct answer and learn more.

Two years ago, our math teacher, Mr. Alex offered us an answer of a difficult math problem in class. Because the answer seemed a little strange, nobody but I doubted it. Think that his solution might be wrong, I carefully analyzed the problem and try to work it out in a different way. Half a hour later, I managed to find the correct answer. When I showed my answer to her, the teacher praised me for my independently thinking.

From this experience, I have been learnt that questioning can serve as a bridge that helping us to seek the truth.
