Correct Answer: A

Rationale: The correct answer is 'A: Everyone.' In the sentence, the verb 'has' must agree with the singular subject 'Everyone.' 'I,' 'day,' and 'boss' are not the subjects that the verb 'has' must agree with. 'I' is the object pronoun, 'day' is the object of the preposition 'off,' and 'boss' is part of the second clause and not the subject that governs the verb agreement in the first clause.

Correct Answer: A

Rationale: The correct answer is 'A: odor.' In the sentence provided, 'odor' serves as the context clue that helps define 'pungent' as a strong smell. The word 'pungent' commonly refers to something having a sharply strong scent, and 'odor' directly relates to this meaning in the sentence. Choices 'B: room,' 'C: made,' and 'D: tear' do not provide contextual information about the meaning of 'pungent,' making them incorrect choices for defining the word in this context.

Correct Answer: D

Rationale: The correct answer is D (Henry) because the adjectives 'strong and healthy' describe 'Henry.' In this sentence, 'Henry' is the subject being described as strong and healthy, not 'weeks,' 'his,' or 'surgery.' While 'weeks' and 'surgery' are nouns mentioned in the sentence, they are not the nouns being described by the adjectives in question. 'His' is a possessive pronoun referring to Henry and does not match the criteria of being directly described by the adjectives 'strong and healthy.' Therefore, 'Henry' is the noun that the adjectives specifically describe in this context.

Correct Answer: D

Rationale: The correct plural form of the noun 'class' is 'classes.' When forming the plural of 'class,' you add 'es' to the singular form. Choices A, B, and C do not correctly represent the plural form of 'class' and are therefore incorrect. Choice A is the singular form, choice B is incorrect as it includes an apostrophe, and choice C shows possession which is not required for pluralization.
