1. Which of the following meninges is a thin membrane containing numerous nerves and blood vessels that supply nourishment to the underlying brain cells and spinal cord?

• A. Arachnoid mater
• B. Dura mater
• C. Periosteum
• D. Pia mater

Correct answer: D

Rationale: The pia mater is the correct answer. It is a thin, innermost layer of the meninges that contains numerous nerves and blood vessels, providing nourishment to the underlying brain cells and spinal cord. The arachnoid mater (Choice A) is the middle layer of the meninges and does not contain as many nerves and blood vessels as the pia mater. The dura mater (Choice B) is the tough, outermost layer of the meninges and is not responsible for supplying nourishment. The periosteum (Choice C) is a connective tissue membrane covering bones, not part of the meninges.

2. What macromolecules are proteins that speed up chemical reactions and act as biological catalysts?

• A. Lipids
• B. Enzymes
• C. Carbohydrates
• D. Nucleic acids

Correct answer: B

Rationale: Enzymes are proteins that act as biological catalysts, speeding up chemical reactions without being consumed in the process. Lipids, carbohydrates, and nucleic acids do not serve as proteins that function as catalysts; they have different biological roles. Lipids are primarily used for energy storage, structural components, and signaling molecules. Carbohydrates are mainly for energy storage and providing structural support. Nucleic acids are involved in genetic information storage and transfer. Therefore, the correct answer is B: Enzymes.

3. What is the part of speech of the word 'exhaustive' in the sentence: 'Investigators conducted an exhaustive inquiry into the accusations of corruption'?

• A. Noun
• B. Verb
• C. Adverb
• D. Adjective

Correct answer: D

Rationale: The word 'exhaustive' is an adjective in this sentence. Adjectives modify nouns, and in this case, 'exhaustive' is describing the noun 'inquiry.' A noun, verb, or adverb would not be appropriate here. A noun is a person, place, thing, or idea, which 'exhaustive' is not. A verb is an action word, and 'exhaustive' is not functioning as a verb in this sentence. An adverb typically modifies a verb, adjective, or another adverb, but 'exhaustive' is not serving this function in the sentence provided. Therefore, the correct answer is 'D: Adjective.'

4. Which of the following sentences uses second person point of view?

• A. I don't want to make plans for the weekend before I see my work schedule.
• B. She had to miss the last three yoga classes due to illness.
• C. Pluto is no longer considered a planet because it is not gravitationally dominant.
• D. Be sure to turn off all of the lights before locking up for the night.

Correct answer: D

Rationale: The correct answer is D. This sentence uses the second person point of view by directly addressing the reader or listener with the phrase 'Be sure to.' It is instructing or advising someone on what action to take, making it a clear example of second person point of view. Choices A, B, and C all use first person (I) or third person (she, Pluto), which do not involve direct interaction with the reader or listener, unlike the second person point of view present in choice D.

5. Which of the following sentences has correct subject-verb agreement?

• A. The crowd standing outside the club is getting restless.
• B. Most of the cookies we left out on the counter were eaten by the dog.
• C. The upholstered couch and rocking chair we bought together look great in the living room.
• D. Ricotta cheese and pesto taste great on pizza.

Correct answer: C

Rationale: The correct answer is C: 'The upholstered couch and rocking chair we bought together look great in the living room.' This sentence has correct subject-verb agreement with a compound subject. 'The crowd standing outside the club are getting restless' (Choice A) has incorrect agreement as 'crowd' is singular and should be paired with 'is'. 'Most of the cookies we left out on the counter was eaten by the dog' (Choice B) has incorrect agreement as 'cookies' is plural and should be paired with 'were'. 'Ricotta cheese and pesto tastes great on pizza' (Choice D) has incorrect agreement as 'cheese' and 'pesto' form a compound subject that is plural and should be paired with 'taste'.
