Question

Which words are "modal" helping verbs

A. wonder, will, wash
B. mighty, make, most
C. would, might, must
D. would, may, june, july

Answer 1

The correct answer is C: all three of these verbs can be used as modal verbs with another verb, for example:
She would cook;
She might cook;
She must cook

ps in D. "june" is not even a verb!

Answer 2

The correct answer is C, because it is the only one with 'modal' verbs. In A, only 'will' is modal. In B, only 'make' is a verb. In D, there are months involved, which are nouns, not verbs.
