Correct Answer: B

Rationale: The word 'ambiguous' implies having multiple interpretations or uncertainty, which aligns closely with 'vague,' the correct answer. 'Vague' denotes a lack of clarity or definiteness, making it the most appropriate synonym in this context. 'Precise' (Choice A) is the opposite of ambiguous, indicating exactness and clarity, so it is not the best choice. 'Definite' (Choice C) also contrasts with ambiguous as it suggests clear and certain meaning. 'Straightforward' (Choice D) implies directness and simplicity, which does not capture the essence of ambiguity.

Correct Answer: B

Rationale: The correct answer is B because it uses 'literally' to emphasize the magnitude of work, not to exaggerate a simple action. In this sentence, 'literally' is used to convey the idea that the person climbed a significant amount of paperwork, highlighting the challenging and overwhelming nature of the task. Choices A, C, and D use 'literally' inappropriately by exaggerating or using the word in a non-literal sense. In choice A, 'died laughing' is a common expression and not meant to be taken literally. Choice C describes a figurative expression, not a literal one. Choice D involves the supernatural, which is not a literal occurrence.

Correct Answer: A

Rationale: Option A correctly uses the comparative degree by comparing the quality of two movies with the word 'better.' This sentence demonstrates a comparison between two items in terms of quality, making it the correct use of the comparative degree of an adjective. Choice B uses the superlative degree ('tallest') instead of the comparative degree. Choice C uses the comparative degree correctly but with an adverb ('harder') instead of an adjective. Choice D uses the comparative degree correctly, but it compares the temperature of two coffees rather than the quality of the coffee.

Correct Answer: C

Rationale: Establishing a style guide with agreed-upon terminology and formatting is the most effective technique to maintain consistency in writing style. A style guide ensures that writers adhere to specific guidelines regarding tone, terminology, and formatting, thereby creating a cohesive and uniform writing style across different pieces of writing. This consistency helps enhance readability and reinforces the brand or voice associated with the written content. Choices A, B, and D are incorrect because they do not promote consistency in writing style. Writing freely without structure can lead to inconsistency, using different vocabulary and sentence structures can create disjointed writing, and relying solely on thesaurus suggestions may result in awkward or inappropriate word choices that do not contribute to maintaining a consistent writing style.

Correct Answer: C

Rationale: The correct answer is 'effected.' In this context, 'effected' means to produce a result or impression, which aligns with the emotional impact of the strangers' kindness. The other choices are incorrect: A) 'affected' might seem plausible, but 'effected' is a better fit as it implies a direct result. B) 'infected' is incorrect as it implies a negative or harmful impact, which is not the intended meaning. D) 'defected' means to abandon allegiance, which is not relevant in the given sentence.
