To determine if your solutions are correct, let's go through each question:

1. "There's someone knocking at the door! Who can it be at this time of night?" "___ Helen. She said she might come round to watch the midnight movie on TV."
Your choices: A and B

The correct answer is B: That'll be. This is the most natural and appropriate response to indicate possibility, as someone knocking at the door is a present event and using the future tense with "will" would be appropriate in this context.

2. "I've just received some new sales figures. ___ them very much, I'm afraid."
Your choice: B

The correct answer is B: You won't like. This choice correctly uses the future tense to express a future negative expectation or prediction.

3. Over the next six months, the company __ ten new supermarkets in France.
Your choices: A, B, and C

The correct answer could be any of A, B, or C since all three choices correctly express a future action. Therefore, your choices are correct for this question.

4. ___ with this kind of problem before, I expect, so I'll leave you to get on with it.
Your choices: B and C

The correct answer is B: You are dealing and C: You'll have dealt. Both choices are grammatically correct and express the past experience with the problem and the expectation of the problem being handled.

5. According to sources close to the prime minister's office, the foreign minister ____.
Your choices: B and C

The correct answer is B: is due to resign and C: is about to resign. Both choices express that the resignation is likely to happen in the near future based on information from sources.

In summary, your choices for questions 1, 2, 3, 4 (B and C), and 5 (B and C) are correct. Great job!

2 can also be A.

4 only C.

I agree with your other answers.

6. Well, that's all for today. ___ you next week at the same time, if that's all right.

A: I'm going to see; B: I'm seeing; C: I'll see

I choose A; B, and C

7. Next year ___ some time travelling, and then look for a teaching job.
A: I'm spending; B: I'm going to spend; C: I'll spend

I choose B and C

8. The problem we have with Jack is that he ___ insist on opening all the windows in the cold weather.
A: is going to; B: is about; C: will

here I have no idea... going to is used for personal plan and intensions, when the cause of a possible event is present or for decisions about the future. Be about is used to describes what is going to happen very soon. And will for many things, like factual predictions, habits which the speaker disapproves, for an assumption taken from the facts....
I think will fits best, but I sounds queer to me.

9. There's not much bread, I'm afraid. I hope ___ eat it all before the others arrive!
A: you won't; B: you aren't about to; C: you're not going to

I choose A and C

I agree with your other answers.
