Questioning can lead to 61 (search) for an answer. If we are in the habit of raising doubts as to 62 or not the thing we are told is true, we can find the correct answer and learn more.
Two years ago, our teacher 63 (offer) us an answer to a difficult math problem in class. Although the answer seemed a little strange, nobody 64 I doubted it. Thinking that his answer might be wrong, I 65 (careful) analyzed the problem and tried to work 66 out in a different way. Half an hour later, I managed 67 (find) the correct answer. When I showed my answer to him, the teacher praised me for my 68 (depend) thinking.
From this experience, I have learned that questioning can serve as 69 bridge that helps us to seek the 70 (true).
