Choose the correct answer. Mike __ to learn the poem and he can't tell it.

The sentence implies a completed action that has a present result (he can't tell it). This structure is characteristic of the present perfect tense. Therefore, 'has forgotten' is the most appropriate choice to indicate that Mike forgot the poem, leading to his inability to recite it. The other options do not fit the context as well: 'has been forgetting' suggests a repeated or ongoing action, 'forgets' is simple present and doesn't convey the consequence, and 'forgot' is past simple and lacks the connection to the present inability.Final Answer: has forgotten
