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.

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: 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: C

Rationale: The word 'shear' means to cut, while 'sheer' in this context means 'complete' or 'unqualified.' The correct spelling in the sentence should be 'sheer.' Choice A, 'peeked' is the correct past tense of 'peek,' meaning to glance quickly or briefly. Choice B, 'through' is the correct preposition to indicate moving in one side and out the other. Choice D, 'scene,' is the correct term for a part of a play or movie, not 'seen,' which is the past participle of 'see.'

Correct Answer: A

Rationale: The correct answer is A. A compound sentence consists of two independent clauses joined by a conjunction or a semicolon. In sentence A, 'The sky is clear' and 'the stars are bright' are two independent clauses joined by the conjunction 'and.'<br>Choice B is a complex sentence as it has a dependent clause ('Although it was late') and an independent clause ('he stayed up').<br>Choice C is a simple sentence with only one subject and one verb.<br>Choice D is a complex sentence with a dependent clause ('While she reads') and an independent clause ('she listens to music').
