If it is clear who/what we are talking about, we can use possessive pronouns. And we use possessive pronouns instead of a possessive adjective + noun.The corresponding form of the possessive pronoun for the subject pronoun ‘she’ is ‘hers’.
Who are these people? I don't remember ______ .
they
their
them
themselves
We use subject pronouns ‘I’, ‘you’, ‘he’, ‘she’, ‘we’, ‘they’ for people, and we use them before the verb (the predicate) in sentences. The corresponding object pronouns ‘me’, ‘you’, ‘her’, ‘him’, ‘us’ and ‘them’ are used after the verb in sentences. In the test question ‘Who are these people?’ instead of the noun ‘people’ we can use a subject pronoun ‘they’ – ‘Who are they?’, therefore, in the test answer we should use the object pronoun ‘them’ that corresponds with the subject pronoun ‘they’.
