Correct Answer: C

Rationale: The correct answer is 'C: a lot of homework'. In this case, 'homework' is an uncountable noun, so it does not take a plural form like 'homeworks'. The phrase 'a lot of' is used to quantify uncountable nouns, making it the appropriate choice in this context. Choices A, B, and D are incorrect because 'homework' should not be pluralized, and the phrase 'many' is not suitable for uncountable nouns.

Correct Answer: C

Rationale: The correct answer is C, tense disagreement. The sentence contains a tense disagreement between 'was' and 'is.' 'She is a fierce competitor' and 'nothing is going to keep her' are in the present tense, while 'was going to keep her' should also be in the present tense to maintain consistency. Choices A, B, and D are incorrect because the issue in the sentence is related to verb tense, not diction, word choice, or transition words.

Correct Answer: D

Rationale: The word 'outside' is the adverb in the sentence. An adverb is a word that modifies a verb, adjective, or another adverb. In this sentence, 'outside' modifies the verb 'go' by indicating the location where the action is taking place. Choices A, B, and C are incorrect because 'We' is a pronoun, 'should' is a modal verb, and 'go' is the main verb in the sentence, none of which function as adverbs.

Correct Answer: D

Rationale: 'Halves' is the correct plural form of 'half.' In this case, 'halves' is the plural form of 'half,' referring to two equal parts of a whole. Choices A, B, and C are incorrect as 'chieves,' 'prooves,' and 'razores' are not valid plural forms of the respective singular nouns.

Correct Answer: A

Rationale: Option A presents a correctly punctuated compound sentence. It consists of two independent clauses 'Condors are protected by laws' and 'many people fear they will soon become extinct,' which are appropriately joined by a comma and the coordinating conjunction 'but.' In contrast, in option B, the sentence only lists items without independent clauses. Option C combines phrases without independent clauses, and Option D incorrectly uses a comma before the coordinating conjunction 'but' without an independent clause following it.
