Question

Accepted Answer

Here are the corrections:

44. Our society (A) seems to have (B) an unhealthy (C) obsession with (D) staying young.
   - 'staying' should be in the gerund form (-ing) to be grammatically correct.

45. All you need (A) to hang the mirror (B) on the wall (C) is a hammer and (D) some nails.
   - The subject-verb agreement error is corrected by using 'is' instead of 'are'.

46. Bob asked (A) what time the office (B) would close that evening (C) and I said I (D) didn't know.
   - 'will close' should be replaced with 'would close' to indicate a future action from a past perspective.

47. I was made (A) to wait four hours (B) before I was (C) examined by (D) a doctor.
   - 'to wait' should be included to indicate the action 'I' was forced to do.

48. Claire insisted (A) that we all went (B) round to (C) her flat for (D) coffee.
   - 'on we all went' is incorrect; instead, use 'that we all went' to express Claire's insistence.
