Logan had already forgiven Marianne for telling his secret, and so when he was presented with a chance to treat her in kind, he simply did what he did best-he kept his mouth shut. Which of the words in the sentence above is a past participle?

Correct Answer: B

Rationale: The correct answer is 'forgiven' as it is a past participle. A past participle is used to indicate an action that has already occurred in the past. In this sentence, 'forgiven' describes the state of Logan having forgiven Marianne. Choice A, 'telling', is a present participle, not a past participle, which is used for ongoing or continuous actions. Choice C, 'and', is a conjunction that connects phrases or words. Choice D, 'treat', is a verb in its base form, not a past participle.

Correct Answer: A

Rationale: The word 'engendered' in this context means to cause something to come into existence or to bring about. In the sentence, it indicates that the connection sparked an insatiable curiosity within Helen, suggesting that it created or triggered this strong curiosity in her. Choice B, 'Made sense of,' is incorrect as 'engendered' does not imply making sense of something. Choice C, 'Connected,' is incorrect as 'engendered' goes beyond just establishing a connection, it means to cause or produce. Choice D, 'Satisfied,' is incorrect as 'engendered' does not mean satisfied, but rather initiating or creating something.

Correct Answer: A

Rationale: The syllable '-tion' is a suffix that is commonly added to verbs to turn them into nouns. For example, the word 'action' is formed by adding '-tion' to the verb 'act.' This transformation changes the verb into a noun representing the act itself. Therefore, option A correctly identifies '-tion' as a suffix that turns a verb into a noun. Choices B, C, and D are incorrect because they misidentify '-tion' as a different type of affix (prefix, infix) and incorrectly associate it with nouns, pronouns, verbs, or adjectives instead of its actual function of transforming verbs into nouns.

Correct Answer: C

Rationale: The word "bark" is used in two different contexts in the sentences provided. In the first sentence, "bark" refers to the covering of a tree, while in the second sentence, it refers to a sound made by a dog. Therefore, option C correctly states that "bark" has different meanings in each sentence - plant covering in the first sentence and a sound in the second. Option A is incorrect because the meanings are clear from the context. Option B is incorrect as the meaning is not defined by the references to the dog or the tree but by the context of the sentences. Option D is incorrect because there is no misspelling of the word in either sentence.

Correct Answer: D

Rationale: Choice D correctly conveys that the mechanic used a computer to perform diagnostic tests on the car. It is concise and clear, effectively communicating the main point without unnecessary details. Choices A, B, and C include unnecessary repetition or do not convey the information as clearly as choice D. For instance, choice A adds unnecessary repetition by mentioning 'performing diagnostic tests' twice, while choices B and C introduce additional clauses that make the sentence less concise and direct.
