Correct Answer: B

Rationale: Parallel structure means using the same grammatical form for elements in a list. Option (B) uses parallel gerunds ('reading,' 'watching,' 'spending'), making it the correct choice. The other options have inconsistencies in the form of the listed activities, making them grammatically incorrect. Option (A) starts with 'I enjoy' but then switches to '-ing' verbs. Option (C) changes from 'like' to '-ing' verbs, breaking parallelism. Option (D) lists 'reading' correctly but then switches to singular nouns ('movies,' 'friends'), which is not parallel.

Correct Answer: B

Rationale: The word 'growing' in the sentence 'He felt a growing sense of unease' is functioning as an adjective. It describes the sense of unease, indicating a characteristic of the sense rather than an action (verb), a person, place, thing, or idea (noun), or modifying a verb, an adjective, or another adverb (adverb). Therefore, 'growing' is an adjective in this context.

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: C

Rationale: The main function of transition words and phrases in writing is to connect ideas smoothly and guide the reader's flow. They serve to establish logical relationships between different parts of the text, ensuring coherence and facilitating a clear progression of thoughts. Choice A is incorrect as transition words are meant to enhance clarity and coherence, not add unnecessary embellishments. Choice B is incorrect because while transition words can provide emphasis, their primary role is in facilitating the flow of ideas. Choice D is also incorrect as introducing opposing viewpoints and counterarguments is typically done through different means such as specific phrases or signal words.

Correct Answer: A

Rationale: The given sentence combines multiple independent clauses without appropriate punctuation or conjunctions, creating a run-on sentence. A run-on sentence occurs when two or more independent clauses are joined without the necessary punctuation or coordination. In this case, the sentence lacks the proper conjunction or punctuation between 'store' and 'bought,' resulting in a run-on sentence. Choice B, 'Comma splice,' is incorrect because a comma splice involves joining two independent clauses with just a comma, which is not the case in the given sentence. Choice C, 'Dangling modifier,' is incorrect as there are no misplaced modifiers in the sentence. Choice D, 'Subject-verb agreement,' is also incorrect as the error in the sentence does not involve subject-verb agreement but rather the incorrect combination of independent clauses.
