Which of the following prefixes means 'with'?

Correct Answer: C

Rationale: The correct answer is 'C: con-'. The prefix 'con-' means 'with', indicating being together or having a connection. - 'Bio-' means life or living organisms, not 'with'. - 'Per-' means through or completely, not 'with'. - 'Trans-' means across or beyond, not 'with'. Therefore, 'con-' is the only prefix among the options provided that signifies the meaning 'with'.

Correct Answer: A

Rationale: The term 'monochromatic' refers to something that has only one color. Choice A, 'having one color,' is the correct description for monochromatic. Choices B, C, and D are incorrect as 'monochromatic' does not mean 'having many parts,' 'having a lot of time,' or 'having too much heat.' Monochromatic specifically conveys the idea of consisting of or using only one color, making Choice A the correct answer.

Correct Answer: D

Rationale: The correct conjunction is 'Although.' In this sentence, there is a contrast being made between the difficulty of the class and Allison's success, indicating that despite the class being difficult, she excelled. 'If' implies a condition, 'Since' indicates a reason, and 'Because' shows causation, which do not fit the context of the sentence where a contrast is being expressed.

Correct Answer: B

Rationale: The correct answer is B, 'He ate a lot on vacation, but he did not gain any weight.' The conjunction 'but' is used to show a contrast between the two clauses. Choices A, C, and D do not effectively demonstrate the contrast between eating a lot and not gaining weight, making them incorrect. Choice A introduces a conditional relationship that is not present in the original sentences. Choice C implies a causal relationship that is not intended. Choice D also suggests a causal link that is not appropriate given the context.

Correct Answer: A

Rationale: The correct answer is 'A: Coordinate clause.' In the sentence 'I ate, and he drank,' 'I ate' and 'he drank' are coordinate clauses. They are both independent clauses that are joined by the coordinating conjunction 'and.' A coordinate clause is a type of independent clause that is equally important and balanced within a sentence. A dependent clause cannot stand alone as a complete sentence and relies on an independent clause. A subordinate clause is a type of dependent clause that functions within a sentence to provide additional information but does not express a complete thought. An independent clause, on the other hand, can stand alone as a complete sentence.

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.'

Correct Answer: D

Rationale: In this sentence, 'bass' refers to a guitar with four strings that makes low sounds. The context of Natalie practicing suggests that it is referring to a musical instrument, specifically the bass guitar, rather than a fish, sound, or voice. Therefore, the correct answer is D. Choice A, 'Kind of fish,' is incorrect as the sentence context does not relate to fish. Choice B, 'Low and deep sound,' is incorrect because the sentence refers to practicing an instrument, not just a sound. Choice C, 'Lowest male singing voice,' is also incorrect as the sentence context is not related to singing but to playing an instrument.

Correct Answer: A

Rationale: The correct answer is 'A: Everyone.' In the sentence, the verb 'has' must agree with the singular subject 'Everyone.' 'I,' 'day,' and 'boss' are not the subjects that the verb 'has' must agree with. 'I' is the object pronoun, 'day' is the object of the preposition 'off,' and 'boss' is part of the second clause and not the subject that governs the verb agreement in the first clause.

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.
