Which of the following defines the word 'unilateral'?

Correct Answer: A

Rationale: The correct answer is A: 'Performed by one person.' 'Unilateral' means something done by one person or group without the agreement of another. Choice B is incorrect as it suggests the opposite of what 'unilateral' means. Choice C is incorrect as it does not capture the essence of 'unilateral.' Choice D is incorrect as it is not directly related to the definition of 'unilateral.'

Correct Answer: B

Rationale: The correct answer is 'B: styles.' 'Styles' is the correct plural form of 'style.' 'Oxes' in choice A is incorrect; the plural of 'ox' is 'oxen.' 'Monarchys' in choice C is incorrect; the correct plural form of 'monarchy' is 'monarchies.' 'Clutchs' in choice D is incorrect; the correct plural form of 'clutch' is 'clutches.' Therefore, 'styles' is the only word written in the correct plural form among the choices provided.

Correct Answer: C

Rationale: Choice C is the correct answer. The sentence is punctuated correctly with commas separating the city, state, and the rest of the sentence. In Choice A, there should be a comma after 'California' to correctly separate the city and state. Choice B lacks a comma after 'California,' creating a run-on sentence. Choice D incorrectly uses a comma before the year '2011,' which disrupts the flow of the sentence.

Correct Answer: B

Rationale: An indirect quotation does not require quotation marks as it paraphrases what was said without directly quoting it. Sentence B, 'John F. Kennedy announced plans to go to the moon,' is an example of an indirect quotation as it conveys the information without using the exact words spoken by Kennedy. Choices A, C, and D directly quote the individuals and thus require quotation marks, making them incorrect answers.

Correct Answer: A

Rationale: The correct answer is A: 'Let me know.' This is a complete sentence as it contains a subject ('me') and a verb ('know'). Choice B, 'On the subject of philosophy,' is a prepositional phrase and does not form a complete sentence as it lacks a subject and verb. Choice C, 'Depending on the type of books you like,' is a dependent clause and does not stand alone as a complete sentence. Choice D, 'Where there are lots of people,' is a dependent clause as it begins with a subordinating conjunction ('where') and does not function as a complete sentence on its own.
