Here are the answers to the questions:

15. Idahosa said he is good in long jump, isn't he?

    • The correct option is B.

16. They aren't sure yet, are they? No, they aren't.

    • The correct option is C.

17. There were fewer infant deaths in town last year than in previous years.

18. Although he was late, he did not rush.
