Question

Fill in the blank with a suitable modal with the help of the hint in the brackets:

I think everybody _____ learn a foreign language. (advice)

• A. can
• B. should
• C. will
• D. must

Answer 1

The correct option is B should

Options A and B: The words 'I think' refer to an opinion or suggestion. They are usually used when one is about to state their opinion. In that case, we use 'should'.
'Should' expresses a suggestion. It relates to the given sentence, as the subject 'I' mentions an advice/suggestion. Hence, option B is correct.
'Can' expresses an ability, and not a suggestion. So 'can' is not a very suitable option. Hence option A is incorrect.
Option C: 'Will' refers to a future action. In this context it indicates a prediction of the future. The meaning thus formed is ambiguous. Hence this option isn't suitable.
Option D: 'Must' is a stronger form of 'should'. It refers to something that should be done due to necessity. This meaning isn't very suitable as the subject 'I' does not imply that 'learning a foreign language' is a necessity.
Hence D is also incorrect.
