1. The train to London (leaves/will leave) from platform seven in ten minutes.
To complete this sentence, we need to choose between the present simple tense ("leaves") and the future tense ("will leave"). In this case, we should use the future tense "will leave" because the action of the train leaving will happen in the future, specifically in ten minutes.

2. How old (is he going to be/will he be) in March?
To complete this sentence, we need to choose between the future continuous tense ("is he going to be") and the future simple tense ("will he be"). Since we are talking about his age in March, which is a specific point in the future, we should use the future simple tense "will he be."

3. On Friday we (will go/are going) to the theatre.
To complete this sentence, we need to choose between the future simple tense ("will go") and the present continuous tense ("are going"). Since the action of going to the theater is planned and scheduled for the future, we should use the future simple tense "will go."

4. We are having/will have) a party on Saturday night.
To complete this sentence, we need to choose between the present continuous tense ("are having") and the future simple tense ("will have"). Since the party is already planned and scheduled for Saturday night, we should use the present continuous tense "are having."

5. I would like you to make tea. OK. I (will do/am going to do) it.
To complete this sentence, we need to choose between the future simple tense ("will do") and the future continuous tense ("am going to do"). Both options are correct, but using "will do" emphasizes the decision made at the moment of speaking, while using "am going to do" implies a prior plan or intention. Either choice is acceptable.

6. The weather forecast says we (won't have/are not having) snow tomorrow.
To complete this sentence, we need to choose between the future tense with negative ("won't have") and the present continuous tense with negative ("are not having"). Since we are talking about a future prediction made by the weather forecast, we should use the future tense with negative "won't have."

7. Look at the clouds. It (is going to rain/will rain).
To complete this sentence, we need to choose between the future continuous tense ("is going to rain") and the future simple tense ("will rain"). In this case, both options are acceptable. However, using "is going to rain" suggests that the speaker sees signs or indications of rain in the near future.

8. Rob (will swim/will be swimming) in the Black Sea this evening.
To complete this sentence, we need to choose between the future simple tense ("will swim") and the future continuous tense ("will be swimming"). Since we are talking about an activity that will happen at a specific time in the future, we should use the future simple tense "will swim."

9. I think, mum and dad have come. Have they? I (will go and meet/am going to meet) them.
To complete this sentence, we need to choose between the future simple tense ("will go and meet") and the future continuous tense ("am going to meet"). Both choices are correct, but using "will go and meet" implies a sudden decision made at the moment of speaking, while using "am going to meet" suggests a prior plan or arrangement. Either choice is acceptable.

Overall, it is important to understand the context and time frame of the sentences in order to choose the appropriate verb forms. The verb forms used should accurately express whether the actions or events are happening in the present, future, or as part of a plan or intention.
