Is the sentence 'Mary visited us when we lives at 830 Marple Ln.' grammatically correct?

• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (B)

This sentence runs into tense and subject-verb agreement issues in the clause after when. The main verb Mary visited is in the past tense, so the clause that describes the timing should align with that past reference.

Using “we lives” is incorrect because we is plural and requires the verb live, not lives. The natural past-tense alignment would be: “Mary visited us when we lived at 830 Marple Ln.” If you want to show ongoing past action, you could say “Mary visited us when we were living at 830 Marple Ln.” If you were describing a habitual present situation, you could say “Mary visits us when we live at 830 Marple Ln,” but that changes the meaning.

So the corrected version depends on what you want to convey, with the simplest past-tense alignment being: “Mary visited us when we lived at 830 Marple Ln.”
