Dialogue One:
Alice: (1) South America? He knows so much about it.
a) Has Jack been to b) Was Jack in

The correct answer is a) Has Jack been to. We use the present perfect tense (has/have + past participle verb) when we want to talk about an action that started in the past and is still relevant or has an effect in the present. In this case, Alice is talking about Jack's knowledge of South America, which indicates that he has been there in the past and the experience is still relevant.

Bob: Jack (4) there only a few months ago.
a) has been b) was

The correct answer is a) has been. Bob is using the present perfect tense to talk about Jack's recent trip to South America. He is emphasizing that Jack's visit happened just a few months ago, indicating that the action is still recent and relevant.

Dialogue Two:
Andrew: What (1)Paul? You look terrible.
a) has happened b) happened

The correct answer is a) has happened. Andrew is asking about a recent event or situation that has affected Paul's appearance. The use of the present perfect tense suggests that Andrew is referring to something that has happened recently and is still relevant.

Paul: Can’t you see? I (2) my leg.
a) have broken b) broke

The correct answer is a) have broken. Paul is using the present perfect tense to talk about the current state or condition of his leg. He broke his leg in the past, but the effect of this action is still present.

Andrew: When (3)it, Paul?
a) have you broken b) did you break

The correct answer is b) did you break. Andrew is asking about the specific time in the past when Paul broke his leg. The use of the past simple tense (did + base form of the verb) is appropriate when referring to a specific time or action in the past.

Paul: It (4)the other day.
a) has happened b) happened

The correct answer is b) happened. Paul is referring to the past event of breaking his leg, indicating that it occurred specifically on "the other day." The use of the past simple tense is appropriate to describe a completed action in the past.
