Question

fill in the blank with the correct modal verb. select options below i am not sure where maria is, but she choose... be at the library. options: does, might, is

Explanation:

The sentence "I am not sure where Maria is, but she ____ be at the library" requires a modal verb to express possibility. "Might" is a modal verb used for expressing possibility, especially when there is uncertainty. "Does" is a helping verb for present simple tense (with main verbs) and "is" is a linking verb, neither of which fit here to express possibility. So "might" is the correct choice.

Answer:

might
