The accident _____ if the motorist had obeyed the speed limit sign.

Correct Answer: B

Rationale: The correct answer is 'never would have happened.' This choice correctly expresses the hypothetical outcome that did not occur due to the motorist obeying the speed limit sign. The phrase 'never would have happened' is the most suitable option in this context as it indicates a past event that was prevented by following a certain condition. Choice A ('could have happened') is incorrect as it does not convey the same level of certainty and definiteness as 'never would have happened.' Choice C ('wouldn't have occurred') is close but lacks the emphasis on the event not taking place at all. Choice D ('could happen') is in the present tense and does not fit the context of a past hypothetical situation.

Correct Answer: A

Rationale: The correct answer is 'get' because it appropriately indicates a future action in the sentence. In English, when 'when' is used in future time clauses, the following verb should be in the present simple tense to indicate a future event, making 'get' the correct choice. Choices B, C, and D are incorrect. 'Will get' is redundant after 'when' in this context, 'return' is not the appropriate tense for a future action, and 'came' is in the past tense, which is not suitable for a future event.

Correct Answer: A

Rationale: In this context, 'experience' is the most appropriate term because it refers to the practical knowledge and exposure someone has gained over time. When selecting a candidate from interviews, experience is often a crucial factor as it demonstrates the individual's capability to perform tasks effectively based on past scenarios encountered. 'Skills' (choice B) are specific abilities that can be learned or developed, 'qualities' (choice C) refer to personal characteristics, and 'knowledge' (choice D) is theoretical understanding, none of which directly reflect practical exposure gained over time.

Correct Answer: B

Rationale: The correct answer is B: 'envelope.' The mail carrier typically delivers envelopes containing mail to every mailbox on the block. Envelopes are commonly used to protect and contain letters, making them the most suitable choice in this context. Choices A, C, and D are incorrect because while the mail carrier may deliver letters, packages, or documents, the most common item placed in mailboxes is an envelope containing mail.

Correct Answer: A

Rationale: The correct answer is 'no' as it implies the absence of vegetables, indicating that he did not consume any vegetables along with the fried chicken. 'Some' (choice B) implies an unspecified quantity of vegetables were eaten, 'little' (choice C) implies a small amount of vegetables, and 'few' (choice D) is used for countable items, not for uncountable items like vegetables.
