We all answer questions every day. But how do you know if your answer is actually reasonable (合理的)? Here are four simple ways to check.

Think about the logic (逻辑)

A reasonable answer must follow basic logic. If your answer disagrees with common knowledge, something is probably wrong. For example, if a math problem asks how many apples are in a basket, and you get “-5”, that isn’t reasonable. ____1____ Always ask yourself, “Does this fit the real world?”

Use real-life examples

Let’s say you are solving a science question, “Why do we feel cold in winter?” A reasonable answer is, “Because the temperature drops.” Now compare that with an unreasonable answer, “Because the sun gets angry.” The first answer uses facts. ____2____ When you give an answer, try to connect it to something you have actually seen or experienced.

____3____

Before you finish, ask yourself, “Is my answer close to what I expected?” Let’s do a quick math check. If you calculate 38×4, and you get 152, that feels right. But if you get 1,520, that is too big. Compare your answer with an estimate (估算). If they are very different, go back and check your work.

Ask yourself questions

This is the easiest method. Just ask yourself, “Is the answer reasonable?” “Can I explain the answer to a friend?” “Would my teacher accept the answer?” If you can’t explain your answer in simple words, you might not fully understand it yourself. ____4____

In short, a reasonable answer is logical, factual (事实的), close to your estimate, and easy to explain. ____5____ You will make fewer mistakes and feel more confident.

A. You cannot have negative apples.

B. Compare it with what you expected.

C. Connect it with what you already know.

D. A good answer should be easy to talk about.

E. The second sounds funny but has no science behind it.

F. Next time you finish a question, spend a few seconds checking.
