Sure! Here is a detailed response with corrections and explanations for each sentence:

1) By the beginning of the news program, we will be returning home.
Correction: By the beginning of the news program, we will have returned home.

Explanation: We use the future perfect tense (will have + past participle) to talk about an action that will be completed before a specific time in the future. In this case, the action of "returning home" will be completed before the beginning of the news program.

2) I'll tell Pamela about the party. I'll have been seeing her at the university anyway.
Correction: I'll tell Pamela about the party. I'll see her at the university anyway.

Explanation: The future perfect continuous tense (will have been + present participle) is used to indicate an ongoing action that will be completed at a certain point in the future. However, in this sentence, the action of "seeing her at the university" is not an ongoing action but a simple action, so we should use the simple future tense (will see) instead.

3) At this time tomorrow, Jack will have taken his driving test.
Correction: At this time tomorrow, Jack will be taking his driving test.

Explanation: The future perfect tense is not required here because "taking his driving test" will happen in the future, but it will not be completed before a specific time. The simple future tense (will be taking) is sufficient to express this.

4) By the end of July, she will have run this café for ten years.
Correction: By the end of July, she will have been running this café for ten years.

Explanation: The future perfect continuous tense (will have been + present participle) is used to talk about an ongoing action that will be completed before a specific time in the future. In this case, "running this café" is an ongoing action that will be completed by the end of July.

5) Will Ron have fixed this bike by 12 o'clock tomorrow?
Correction: Will Ron fix this bike by 12 o'clock tomorrow?

Explanation: The future perfect tense is not required here because the action of "fixing the bike" will happen in the future but will not be completed before a specific time. The simple future tense (will fix) is sufficient to express this.

6) Will you be going out a bit later? Can you buy a magazine for me?
Correction: Will you go out a bit later? Can you buy a magazine for me?

Explanation: The future continuous tense (will be + present participle) is not necessary here because "going out" is not an ongoing action but a single action. Thus, we should use the simple future tense (will go) instead.

7) By next Friday, Susan will have passed all her exams.
Correction: By next Friday, Susan will pass all her exams.

Explanation: The future perfect tense is not required here since the action of "passing all her exams" will happen in the future, but it will not be completed before a specific time. The simple future tense (will pass) is sufficient to convey this.

8) By 8 o'clock, the boys will have played football for three hours.
Correction: By 8 o'clock, the boys will have been playing football for three hours.

Explanation: The future perfect continuous tense (will have been + present participle) is needed here because "playing football" is an ongoing action that will be completed before a specific time (8 o'clock).

9) Will Sam be preparing for his English test at 11 o'clock tomorrow morning?
Correction: Will Sam prepare for his English test at 11 o'clock tomorrow morning?

Explanation: The future continuous tense (will be + present participle) is not necessary here because "preparing for the English test" is not an ongoing action but a single action. We should use the simple future tense (will prepare) instead.

10) By the beginning of next week, Bob will have been working in our office for ten days.
Correction: By the beginning of next week, Bob will have worked in our office for ten days.

Explanation: The future perfect continuous tense (will have been + present participle) is not appropriate here because "working in our office" is not an ongoing action but a completed action. We should use the future perfect tense (will have worked) to express that he will complete ten days of work in our office by the beginning of next week.

I hope this detailed explanation helps you understand the corrections made to each sentence!
