which poem

Explanation:

Where is the poem

Answer 2

Answer:

The statement is in past tense; For converting it to passive voice 'The poem' is made the subject; the auxiliary verb following it should be singular since it is a singular subject; so 'learned' is changed to 'was learned' and the doer is introduced by preposition 'by'; so the correct answer is 'The poem was learned by Alex'.
