1. What is the role of RNA in the regulation of gene expression?

• A. Provides energy for the process
• B. Controls the timing and location of protein synthesis
• C. Translates the genetic code into amino acids
• D. Stores genetic information

Correct answer: B

Rationale: A) RNA does not provide energy for the process of gene expression. Energy is typically provided by molecules like ATP. B) RNA plays a crucial role in controlling the timing and location of protein synthesis through processes like transcriptional regulation, RNA splicing, and post-transcriptional modifications. It helps determine when and where specific proteins are produced in the cell. C) While mRNA translates the genetic code into amino acids during the process of translation, this is not the primary role of RNA in the regulation of gene expression. D) RNA does not store genetic information in the same way that DNA does. DNA is the molecule responsible for storing genetic information in the form of genes. Therefore, option B is the most appropriate choice as it accurately describes the role of RNA in regulating gene expression.

2. Which of the following substitutions best captures the meaning of the word 'obsequious' in the sentence: 'The young apprentice was obsequious to his master, always eager to please'?

• A. showing deference
• B. poorly dressed
• C. reserved
• D. aggressive

Correct answer: A

Rationale: The word 'obsequious' means excessively submissive or eager to please, often to the point of showing deference. In this context, 'showing deference' best captures the meaning, indicating respect or submission rather than being poorly dressed, reserved, or aggressive. 'Poorly dressed' (B) is unrelated to the meaning of obsequious. 'Reserved' (C) suggests a different behavior that is opposite to being obsequious. 'Aggressive' (D) is the opposite of obsequious and does not fit the context of the sentence.

3. Which of the following words functions as a pronoun in the sentence below? Anne-Charlotte and I will be driving together to the picnic this weekend.

• A. Be
• B. This
• C. Together
• D. I

Correct answer: D

Rationale: In the sentence provided, 'I' functions as a pronoun. A pronoun is a word that takes the place of a noun. In this case, 'I' replaces the name of the speaker (the person talking), making it a pronoun. 'Be' is a verb, 'this' is a demonstrative pronoun, and 'together' is an adverb indicating the manner in which Anne-Charlotte and the speaker will be driving. Therefore, 'I' is the correct answer.

4. Which of the following sentences contains a correct example of subject-verb agreement?

• A. All of the board members are in agreement on the issue.
• B. Each of the students was concerned about the test scores for the final exam.
• C. Neither of the children is at home right now.
• D. Any of the brownie recipes is perfect for the bake sale.

Correct answer: A

Rationale: The correct answer is A. In this sentence, the subject 'all of the board members' is plural, and the verb 'are' agrees with it. In choice B, 'each of the students' is singular, so the verb should be 'was' instead of 'were.' Choice C should use 'is' instead of 'are' since 'neither of the children' is singular. In choice D, 'any of the brownie recipes' is singular, so 'is' should be used instead of 'are.' Therefore, only choice A demonstrates proper subject-verb agreement.

5. Identify the predicate in the following sentence: 'The children built a sandcastle on the beach.'

• A. on the beach
• B. built a sandcastle
• C. children
• D. the

Correct answer: B

Rationale: The predicate in a sentence is the part that tells what the subject is doing or what is being done to the subject. In this sentence, 'built a sandcastle' is the predicate as it is the action performed by the subject 'children.' 'On the beach' is a prepositional phrase that provides additional information but is not the predicate. Choice C 'children' is the subject of the sentence, and choice D 'the' is an article referring to 'children,' making them incorrect choices for the predicate.
