**Rule:** The Future Perfect Tense (will have + past participle) is needed here to express an action that will be fully completed before another future event. The action is 'packing the collection', and the future event is 'he moves house'. The packing will be finished before the moving. Option (d) implies the packing will be in progress during the move.

**Rule:** In future time clauses introduced by conjunctions like 'after', 'when', or 'before', the Simple Present Tense is used, not a future tense. The action of finishing homework must happen before the action of calling, so the simple present 'finish' is correct. Option (a) 'will finish' is a common error. Options (b) and (d) are also grammatically incorrect in this structure.

**Rule:** The Simple Present Tense is used for facts of nature or events on a fixed, predictable schedule. The sunrise is a natural event that happens on a regular, timetabled basis. Therefore, 'rises' is the correct form. While (d) is not incorrect, (c) is the standard tense for such events.

**Rule:** The Future Continuous Tense (will be + verb-ing) is used to describe an action that will be in progress at a specific time in the future. The phrase 'This time next week' specifies an exact future moment. The action of relaxing will be ongoing at that point. Option (a) 'will relax' (Simple Future) states a future action but not its continuous nature at a specific time. Option (b) 'am relaxing' is Present Continuous and incorrect here. Option (c) 'will have relaxed' (Future Perfect) implies the action of relaxing will be completed by that time, which is not the intended meaning.

**Rule:** The 'be going to' future is used for predictions based on clear present evidence. The 'strange noise' is the auditory evidence that leads to the logical prediction that the car will break down. Option (a) is a more general prediction, not as strongly linked to the current evidence.

**Rule:** The Future Perfect Tense (will have + past participle) is used to express that a future event will be completed before another future event. The speaker is concerned that the action of the film starting will be finished before they get there. This conveys the urgency. Option (b) is a simple prediction, not focused on the completion.

**Rule:** The Simple Future with 'will' is used to express a prediction based on belief or certainty, especially after phrases like 'I'm sure'. It reflects the speaker's confidence in the future outcome. Option (c) is also possible but 'will' is the classic choice to convey personal certainty.

**Rule:** The Future Perfect Continuous Tense (will have been + verb-ing) is used to emphasize the duration of an action up to a specific point in the future. The phrase 'for ten consecutive years' specifies the duration, and 'Next month' is the future point in time. Option (a) 'will be working' (Future Continuous) indicates an action in progress but doesn't emphasize the duration. Option (c) 'am working' is Present Continuous. Option (d) 'will work' (Simple Future) is a general statement about the future.

**Rule:** The Future Perfect Tense (will have + past participle) is used for an action that will be completed before another moment in the future. 'By the end of their tour' is the future point by which the action of performing in 50 cities will be finished. Option (a) 'will be performing' suggests they will be in the middle of a performance at that time. Options (c) and (d) are present tenses and are incorrect.

**Rule:** Both the Present Continuous ('is departing') and the Simple Present ('departs') can be used for scheduled future events. Present continuous is very common for personal travel plans and arrangements. Option (a) is also correct but (b) is equally, if not more, common in spoken English for this context.
