Answer is Right!
Answer is Wrong!
The correct answer is: should.
You should see a doctor if you have a fever. A fever is a sign that your body is fighting an infection. It is usually not dangerous, but it can be a sign of a serious illness. If you have a fever, it is important to see a doctor to get treatment and to make sure that the infection is not serious.
The other options are incorrect because:
- Must is too strong. You do not have to see a doctor if you have a fever. However, it is a good idea to see a doctor to get treatment and to make sure that the infection is not serious.
- Can is too weak. You should see a doctor if you have a fever. It is important to get treatment and to make sure that the infection is not serious.
- Will is not a correct answer because it is not a command. The question is asking what you should do, not what you will do.
