Correct Answer: C

Rationale: The word 'unscathed' means without harm or damage. The word 'scratch' shares the same root related to physical marks or damage, making it the correct choice. 'Category' and 'scar' do not have the same root as 'unscathed' and are not related to the concept of being unharmed, making them incorrect choices.

Correct Answer: A

Rationale: The correct answer is 'A: herself.' A reflexive pronoun refers back to the subject of the sentence and emphasizes that the subject performed the action on itself. In the sentence 'She prepared herself for the presentation,' 'herself' refers back to the subject 'she,' making it a reflexive pronoun. Choice B, 'she,' is a subjective pronoun used as the subject of the sentence. Choice C, 'presentation,' is a noun and not a pronoun. Choice D, 'for,' is a preposition and not a pronoun.

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: 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.

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.
