Correct Answer: D

Rationale: The correct answer is 'D: Sleepwalker.' A somnambulist is someone who walks or performs other activities while asleep, commonly known as a sleepwalker. In the given sentence, the context of waking up outside in pajamas in the middle of the night indicates an occurrence associated with sleepwalking. Choice A, 'Explorer,' is incorrect as it does not relate to the behavior described. Choice B, 'Magician,' is not related to the context of sleepwalking. Choice C, 'Insomniac,' refers to a person who has difficulty falling asleep or staying asleep, which is not the meaning conveyed in the sentence. Therefore, 'D: Sleepwalker' is the most appropriate choice based on the context clues provided.

Correct Answer: D

Rationale: In the sentence 'I asked a colleague to bring it to you,' the pronoun 'whose' does not fit grammatically. The pronoun 'whose' is used to indicate possession or belonging to someone, which is not relevant in this context. The other pronouns 'my,' 'our,' and 'your' are all appropriate to use in this sentence based on the context of the sentence. Therefore, 'whose' is the correct answer as it does not work in the given sentence.

Correct Answer: B

Rationale: The correct answer is B: 'The cat slept on the mat; she purred softly.' This sentence is a run-on because it contains two independent clauses ('The cat slept on the mat' and 'she purred softly') without proper punctuation. Choice A is incorrect as it is a compound sentence with a coordinating conjunction 'and' joining two independent clauses. Choice C is also incorrect as it is a compound sentence connected by a coordinating conjunction 'so.' Choice D is not a run-on sentence; it is a compound sentence with a coordinating conjunction 'or' joining two independent clauses.

Correct Answer: B

Rationale: The correct answer is B, compound sentence. This sentence consists of two independent clauses ('The sky is blue' and 'the grass is green') that are joined by the coordinating conjunction 'and.' A simple sentence contains a single independent clause. In contrast, a complex sentence has one independent clause and at least one dependent clause. A compound-complex sentence consists of multiple independent clauses and at least one dependent clause, which are not present in the given sentence, making choices A, C, and D incorrect.

Correct Answer: C

Rationale: The correct verb to use in this sentence is 'are.' In English grammar, when the subject is plural like 'girls,' the correct form of the verb to use is 'are.' Choices A, B, and D are incorrect because 'is' is singular, 'am' is first-person singular, and 'ares' is not a valid verb form in English. Therefore, the correct answer is 'are' to match the plural subject 'girls.'
