Correct Answer: A

Rationale: The correct answer is A. A comparison of the language used in two different Shakespeare plays should include citations to support the analysis. Citations are necessary in academic or analytical pieces to give credit to the original sources, especially when comparing specific works. Choices B, C, and D do not require citations as they are more subjective or personal in nature. Choice B, a news article, should be based on facts and not personal analysis. Choice C is a personal opinion, and choice D is a personal essay based on the author's experiences and interests, where citations are not typically needed.

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: D

Rationale: The correct answer is 'Ibexes have adapted to life in the mountains' because it serves as a concluding sentence that summarizes the content of the paragraph. This statement encapsulates the information provided about ibexes living in the Alps and Asian mountains, climbing steep slopes, being sure-footed, and changing their coats in winter. Choice A is incorrect because the text does not specifically mention their agility. Choice B is incorrect as the text only mentions the Alps and Asian mountains, not lowlands. Choice C is also incorrect as the text mentions ibexes climbing steep slopes, not just liking to do so.

Correct Answer: D

Rationale: The sentence follows the rules of punctuation and capitalization for dialogue.

Correct Answer: A

Rationale: The correct use of a semicolon is demonstrated in sentence A: 'I have a test tomorrow; I need to study.' Semicolons are used to connect closely related independent clauses. In this sentence, the semicolon correctly separates the two independent clauses 'I have a test tomorrow' and 'I need to study.' Choice B is incorrect because it separates the clauses improperly by using the semicolon after 'test' instead of after 'tomorrow.' Choice C is incorrect as it lacks a second independent clause to be connected using a semicolon. Choice D is incorrect as it inappropriately adds 'and' after the semicolon, which disrupts the correct use of the punctuation mark to link independent clauses.
