Answer 1

1. When did you come to live here?

- This is a question in the past tense, asking for the specific time or date when the person arrived to live in the current location.

2. I've known my friend since I started school.

- This sentence is in the present perfect tense and indicates that the speaker's friendship with their friend began at the same time they started school. The word "since" is used to show a specific starting point in the past and the action (knowing the friend) continues up to the present.

3. Olivia hasn't eaten since lunchtime.

- This sentence is in the present perfect tense and indicates that Olivia has not eaten anything after lunchtime. The word "since" is used to indicate a specific starting point in the past (lunchtime), and the use of the present perfect tense indicates that the action (not eating) is still ongoing.

4. John arrived home yesterday.

- This sentence is in the past tense and indicates that John arrived at his home the day before the time of speaking.

5. Have you ever tried mango?

- This is a question in the present perfect tense and is asking about whether the person has ever had the experience of trying mango. The use of "ever" indicates that there is no specific time frame being referenced, and the present perfect tense suggests that the action (trying mango) may have happened at some point in the past and may continue into the present.

Answer 2

Here are the correct options for each sentence:

1. When did you come to live here? OR Have you come to live here? (Both options are grammatically correct, but they convey slightly different meanings. The first option asks about the specific time of arrival, while the second option asks if you have come to live here at any point in time.)

2. I've known my friend since I started school. (This sentence indicates that you started knowing your friend when you began school, so "since" is the correct choice.)

3. Olivia hasn't eaten since lunchtime. (This sentence correctly uses the present perfect tense to indicate that Olivia has not eaten from lunchtime up to the present moment.)

4. John arrived home yesterday. (The past tense "arrived" is the correct choice here since it happened in the past, specifically yesterday.)

5. Have you ever tried mango? (The present perfect tense "have you ever tried" is the correct choice when asking about experiences in a person's life up to the present moment.)
