Choose the correct option for each sentence. Focus on agreement
(subject–verb, pronouns, and demonstratives).
Reminder:
- Singular subject → singular verb (often -s in present simple).
- Plural subject → plural verb (no -s in present simple).
- this/that + singular noun; these/those + plural noun.
- Pronouns should match the person/thing: his / her / their, it / they.
Teacher tip: After checking, ask students to explain why each answer is correct.
