Question

card 8
the number of students who plan to boycott the awards assembly astonishes¹ astonish² me.
option 1: astonishes
option 2: astonish

Explanation:

The subject "the number of students..." is a singular subject (since "number" is singular), so the verb should be in the singular form. "Astonishes" is the singular form of the verb, while "astonish" is the base (plural or infinitive) form. So the correct verb to agree with the singular subject is "astonishes".

Answer:

Option 1: astonishes
