**Rule:** In future time clauses introduced by conjunctions like 'as soon as', 'when', 'before', 'after', or 'unless', the Simple Present Tense is used to refer to a future event. The main clause uses a future tense ('we will be able to leave'). Option (a) 'will arrive' is incorrect because 'will' is not used in the future time clause. Option (c) 'is arriving' could be possible for a fixed arrangement, but simple present is standard. Option (d) 'will have arrived' is grammatically incorrect in this structure.

**Rule:** 'Be going to' can be used for predictions based on a present feeling or intuition. 'I have a feeling' is the present evidence, making 'is going to happen' a natural choice to express the prediction. 'Will happen' would also be possible but 'going to' connects more strongly to the present feeling.

**Rule:** 'Will' is often used when reporting a promise or a decision made by someone else. The repairman has made a decision or promise to come tomorrow. This is a simple statement of a future action. Option (a) is also possible for arrangements, but 'will' is a very common way to report such statements.

**Rule:** 'Be going to' is used to talk about a prior intention or a plan. The speaker has already bought the dress and intends to wear it. This is a pre-meditated action, not a spontaneous decision. Option (c) is future perfect. Option (d) is past. Option (a) is incorrect.

**Rule:** 'Be going to' is used to make a prediction based on immediate present evidence. The 'lot of noise' is the current evidence that leads to the predictable result of the baby waking up. Option (a) is a more general prediction, less connected to the present evidence.

**Rule:** The Future Continuous Tense (will be + verb-ing) is used to describe an action that will be in progress at a future time. It's a common way to inform someone of a planned arrangement, indicating what will be happening when they arrive. It implies a definite plan.

**Rule:** This is a First Conditional sentence ('if' + simple present, ... 'will' + base verb). It expresses a likely future result of a current action. The main clause states the predictable consequence. Option (c) 'is going to wake up' is also very similar in meaning and often interchangeable in this context, but 'will' is the classic first conditional structure.

**Rule:** The Future Simple Passive voice ('will be' + past participle) is required because the 'submissions' are the object of the action 'to check'. The action will happen in the future, before the review. Option (a) is active voice. Option (c) is present continuous active. Option (d) is future perfect active.

**Rule:** The Future Continuous Tense (will be + verb-ing) is used to indicate an action that will be in progress over a period of time in the future. 'Between 7 and 8' specifies the time frame during which the action of having dinner will be ongoing. Option (d) means dinner will be finished. Option (b) is a general statement. Option (c) is also possible for arrangements, but (a) is more specific to the ongoing nature of the action.

**Rule:** The structure 'will have to + base verb' is used to express future obligation or necessity, especially in formal announcements. It clearly states a future requirement. Option (d) states completion but misses the sense of obligation. Options (b) and (c) are incorrect.
