**Rule:** The 'be going to' future is used to make a prediction based on a present trend or evidence. 'The way the company is losing money' is the current trend that leads to the logical prediction of bankruptcy. Option (a) is a more general prediction, less tied to the immediate evidence.

**Rule:** This is a First Conditional sentence ('if' + simple present, ... 'will' + base verb). It is used for real and possible future situations. The main clause describes the likely future result if the condition is met. 'will land' is the correct form for this future result. Option (c) is for hypothetical situations.

**Rule:** The Simple Future with 'will' is typically used after phrases expressing probability or belief, such as 'It is unlikely that...', 'I think...', or 'I'm sure...'. It's the standard way to frame a prediction. Option (d) is possible, but 'will' is more common in this formal structure.

**Rule:** This requires a future passive form ('be going to be' + past participle) because the 'wing' is the receiver of the action. 'Be going to' is used because this is a planned, scheduled event. Present continuous passive ('is being opened') would also be possible, but this is a clear and correct alternative.

**Rule:** The Future Perfect Continuous Tense (will have been + verb-ing) is required to emphasize the duration ('for over six hours') of an activity up to a certain point in the future ('by the time they reach their destination'). Option (b) 'will be driving' focuses on the action in progress at that future moment, not its duration. Options (a) and (c) are incorrect.

**Rule:** The 'be going to' form is used for predictions based on strong present evidence. The fact that 'he is stuck in a huge traffic jam' is the clear evidence that leads to the certain prediction that he will be late. Option (a) is a more general prediction, less connected to the immediate evidence.

**Rule:** The Simple Future with 'will' is used for making general predictions about the future, especially when they are considered facts or certainties. The statement is a general prediction about technology. Option (b) is also possible, but 'will' is very common for such factual predictions. Options (a) and (d) are incorrect.

**Rule:** The Present Continuous Tense ('is/are' + verb-ing) is used to talk about fixed plans or arrangements for the future. The phrase 'It is all arranged' confirms that this is a definite plan. Option (c) is for predictions. Option (b) is for timetables. Option (a) is incorrect.

**Rule:** This sentence requires the Future Perfect Passive voice (will have been + past participle) because the subject ('skyscraper') is the receiver of the action. The action of completing will be finished by a future deadline ('by the end of next year'). Option (a) is the future continuous active voice. Option (c) is the simple present passive voice. Option (d) is the simple present active voice.

**Rule:** The Future Perfect Passive voice (will have been + past participle) is needed here. The 'results' are the object of the action. The action of publishing will be completed by a future deadline ('by the end of the month'). Option (c) is active voice. Options (a) and (d) are incorrect.
