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 A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.

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: A

Rationale: The correct phrase to use in this context is 'that has,' indicating possession or similarity between words. Synonyms are words that have meanings similar to those of other words, making choice A the most appropriate selection. Choices B, C, and D are incorrect as they do not correctly convey the relationship of possessing similar meanings between words.

Correct Answer: B

Rationale: The correct answer is 'B: Gelatinous.' Viscous substances have a thick and sticky consistency, similar to the properties of gelatin. 'Watery' and 'fluid' are incorrect as they are opposite in meaning to viscous, which implies thickness and stickiness. 'Dry' is also incorrect as it does not capture the characteristic of being thick and sticky associated with viscosity.
