**Rule:** The Simple Future ('will' + base verb) is used to make a simple, polite request for a future action. The time clause 'When you see him' uses the simple present, and the main clause correctly uses 'will' to form the request. Option (a) is possible but less direct. Options (c) and (d) are incorrect tenses for this type of request.

**Rule:** The Simple Future with 'will' is used to make a spontaneous promise or offer of reassurance. In response to telling someone to relax, the speaker makes an on-the-spot promise to handle the situation. Option (c) suggests a prior plan, which is less fitting for a spontaneous reassurance.

**Rule:** This is a First Conditional question. The 'if' clause uses the simple present ('doesn't work') to describe a future possibility. The main clause correctly uses the Simple Future ('will you do') to ask about the resulting action or plan. Options (a), (c), and (d) are grammatically incorrect in this structure.

**Rule:** The Future Perfect Continuous Tense (will have been + verb-ing) is used to emphasize the duration ('for six hours') of an action leading up to a specific point in the future ('By the time we reach the summit'). It focuses on the length of the continuous effort.

**Rule:** The Simple Future Tense ('will not' + base verb) is used to express a future intention or resolution. The speaker is stating their decision to delay making a choice. The time clause 'until we have all the facts' correctly uses the simple present. Option (d) is future perfect.

**Rule:** This sentence requires a future passive form because the 'building' cannot perform the action of pulling. 'Is going to be + past participle' is the passive form of the 'be going to' future, used for intentions or plans. The demolition is a planned event. Option (b) is active voice. Option (c) is simple present active voice. Option (d) is present perfect passive and refers to a past action.

**Rule:** The Simple Future with 'will' is used to state a future fact or an event that is certain to happen at a scheduled time. The law becoming effective is a formal, certain future event. Option (c) is also possible for schedules, but 'will become' is a very common and formal way to state this.

**Rule:** The Present Continuous Tense ('is/are' + verb-ing) is used for fixed future arrangements. A scheduled speech at a conference is a definite plan. Option (b) would be for a habitual action. Option (c) means the speech will be finished before next week. Option (d) is past tense.

**Rule:** The Simple Future with 'will' is used for a spontaneous decision made at the moment of speaking. The speaker realizes they are out of milk and decides to get some at that moment. Option (a) would imply they had a prior plan to go to the store, which isn't the case. Options (b) and (d) are incorrect.

**Rule:** The 'be going to' form is used for predictions based on clear present evidence. The current time (8:30) and the movie start time (9:00) provide the evidence that they are likely to be late. Option (a) 'will be' is also a prediction but 'going to' is stronger when there is immediate evidence. Options (b) and (d) are incorrect.
