Correct Answer: A

Rationale: The correct answer is 'A: Likely.' An adverb is a word that modifies a verb, adjective, or another adverb. In this sentence, 'likely' is an adverb that modifies the verb 'annoyed,' expressing the probability or likelihood of the action. The other choices, 'B: Annoyed,' 'C: Assigned,' and 'D: Unnecessary,' are not adverbs. 'Annoyed' is a past tense verb, 'Assigned' is a past tense verb, and 'Unnecessary' is an adjective describing the type of busy work assigned. Therefore, 'A: Likely' is the only adverb in the sentence.

Correct Answer: D

Rationale: The correct answer is 'Anthropology.' This term is derived from the Greek words 'anthropos' meaning 'human' and 'logos' meaning 'study.' Therefore, Anthropology refers to the study of humans. Choice A, 'Biology,' is the study of living organisms, not specifically focused on humans. Choice B, 'Philanthropy,' refers to the practice of giving and helping others. Choice C, 'Anthropomorphism,' is the attribution of human characteristics to non-human entities.

Correct Answer: B

Rationale: The correct answer is B: 'is, are'. 'Where is everyone?' requires the singular verb 'is' to agree with 'everyone'. 'What are they doing?' requires the plural verb 'are' to match the plural subject 'they'. Option A 'is, is', does not provide correct subject-verb agreement in the second sentence. Option C 'are, is' and Option D 'are, are' do not maintain consistent subject-verb agreement within the sentences.

Correct Answer: B

Rationale: The correct answer is B: 'The cat sat on the mat after it ate.' 'After it ate' is a dependent clause because it cannot stand alone as a sentence. It is dependent on the main clause 'The cat sat on the mat.' Choice A is a simple sentence without a dependent clause. Choice C is a sentence with a time adverbial modifying 'The cat will sit on the mat,' not a dependent clause. Choice D is a sentence in the present continuous tense, also lacking a dependent clause.

Correct Answer: A

Rationale: The correct answer is 'chiefs.' 'Chief' follows the standard rule for forming the plural by adding an 's' at the end. Choices B, C, and D are incorrect as they do not follow the standard pluralization rule for the word 'chief.' 'Chieves,' 'chievs,' and 'chiefes' are not valid plural forms of 'chief.'
