Давайте разберем каждое предложение по очереди:

1. It was 9 p.m. Sam ________ go home. - a) had to; - b) must.

Ответ: a) had to. (It was a specific time in the past, and "had to" is used to express a necessity or obligation in the past.)

2. You ________ press the button to open this window. - a) had to; - b) must.

Ответ: b) must. (This sentence is a general instruction or rule, and "must" is used to express a necessity or obligation in the present.)

3. Tourists haven't eaten for a few hours, so they ________ be hungry. - a) must; - b) can.

Ответ: a) must. (The lack of food for a few hours suggests a strong possibility that they are hungry, so "must" is appropriate here.)

4. Alex is 20 minutes late, there ________ be something wrong. - a) must; - b) can.

Ответ: a) must. (The lateness of Alex suggests a strong possibility that something is wrong, so "must" is suitable.)

5. John's brother is 6 years old but he ________ write and count. - a) must; - b) can.

Ответ: b) can. (The age and the ability to write and count suggest a capability, so "can" is used here.)

6. Daniel ________ speak Chinese, but maybe he'll learn it someday. - a) couldn't; - b) can't.

Ответ: b) can't. (The sentence suggests that Daniel currently cannot speak Chinese, so "can't" is appropriate.)

7. Nobody ________ tell me what was wrong. - a) could; - b) couldn't.

Ответ: a) could. (The use of "nobody" suggests that there was an inability to tell what was wrong, so "could" is used to express the ability in the past.)

8. Ann earns a lot of money. She ________ buy whatever she wants. - a) can; - b) is able to.

Ответ: a) can. (In this context, "can" is more commonly used to express the general ability in the present.)

9. Will James ________ solve this problem? - a) can; - b) be able to.

10. I've lost my key! I ________ get inside the flat! - a) am not able to; - b) can't.

Ответ: b) can't. (The situation of losing the key suggests a current inability to get inside, so "can't" is used here.)
