1) The train from Kyiv arrives at 6:30 in the morning.

To determine the correct verb form, we need to identify the subject of the sentence. In this case, the subject is "The train from Kyiv." Since the sentence is in present simple tense, we use the base form of the verb "arrive" because the subject is a singular third person noun. Therefore, the correct form of the verb is "arrives."

2) The film starts at quarter to seven.

Again, we need to identify the subject of the sentence, which is "The film." In present simple tense, we use the base form of the verb for singular third person nouns. Therefore, the correct form of the verb is "starts."

3) Sam is not going anywhere this weekend. He is studying for his Maths test.

In this case, we have two sentences. The first one is in present continuous tense, and the second one is in present simple tense.

For the first sentence, we see that Sam is the subject and "is not going" is the verb phrase. This indicates an action that is happening at the time of speaking. Therefore, we use the present continuous tense.

For the second sentence, the subject is still Sam, but the verb is "studying." Since it is a general statement and not happening at the time of speaking, we use the present simple tense.

4) We will have a party at Christmas.

In this sentence, the subject is "We" and the verb is "will have." Since Christmas is a future event, we use the future simple tense with "will" to indicate the plan or intention to have a party.

5) For my birthday, which is this Friday, my mum will cook a chocolate cake.

Similar to the previous sentence, the subject is "my mum" and the verb is "will cook." Since the birthday is a future event, we use the future simple tense with "will" to express an action that will happen in the future.

6) The sun will rise a minute earlier tomorrow.

In this sentence, the subject is "The sun" and the verb is "will rise." Since it is referring to a future event, we use the future simple tense with "will" to indicate the prediction or expectation of the sun rising.

7) This art exhibition opens at 10 a.m.

In this sentence, the subject is "This art exhibition" and the verb is "opens." Since it is a fact or a scheduled event, we use the present simple tense to indicate a regular action or a universal truth.

8) This TV show usually finishes by midnight.

Here, the subject is "This TV show" and the verb is "usually finishes." "Usually" indicates a recurring action, so we use the present simple tense to indicate a regular action or a routine.

Overall, it's important to understand the context and meaning of the sentence to determine the correct tense and verb form.
