Answer 2

The answers are as follows:

31. in ( The sentence talks about an event of scoring goals that took place in the first half. Any event taking place in a stipulated time takes the preposition 'in.')

32. off ( 'Wiped off' acts as a phrasal verb in this sentence. it means that something vanished from the earth totally.)

33. with ( This preposition is applied when a particular element is associated with anything else . In this sentence, the staff is associated with the management. Thus, 'with' is used.)

34. the ( The article 'the' is used since particular mountains are mentioned in the sentence.)

35. a (This takes the article 'a' because any particular entity has not been mentioned, and a vowel is not given.)

36. a ( The article 'a' is placed after 'good boy' since he has not been considered the only good boy. )
