1. Which of the following best explains the meaning of fastidious as it is used in the sentence? "Henry was fastidious about keeping his workspace organized, ensuring that every item was always in its proper place."

• A. fussy
• B. lazy
• C. old-fashioned
• D. hilarious

Correct answer: A

Rationale: In this context, the word 'fastidious' describes someone who pays great attention to detail, is very meticulous, and particular about things being perfect. Henry's behavior of keeping his workspace organized and ensuring everything is in its proper place indicates his meticulous nature. 'Fussy' aligns best with this meaning as it conveys being hard to please and excessively attentive to detail, which accurately describes Henry's behavior. Choices B, C, and D are incorrect as they do not capture the essence of being meticulous and attentive to detail, which is the central meaning conveyed by 'fastidious' in this context.

2. First and foremost, they receive an annual pension payment. T has been reviewed and changed a number of times, most recently to reflect the salary of a high-level government executive. Which of the following would NOT be an acceptable way to revise and combine the underlined portion of the sentences above?

• A. annual pension payment, the amount of which
• B. annual pension payment; the amount of the pension
• C. annual pension payment; over the years since 1958, the amount of the pension
• D. annual pension payment, the amount of the pension.

Correct answer: C

Rationale: Option C is the correct answer because it disrupts the flow of the sentence and introduces unnecessary information. The phrase 'over the years since 1958' is irrelevant in this context and does not contribute to the intended meaning of the sentence. The sentence is focused on the recent changes to the pension, not its historical evolution. Choices A, B, and D provide clear and concise ways to revise and combine the underlined portion of the sentences, maintaining a logical and relevant sentence structure.

3. What is the process of making copies of RNA from DNA called?

• A. Replication
• B. Transcription
• C. Translation
• D. DNA repair

Correct answer: B

Rationale: Transcription is the correct answer. Transcription is the process of making copies of RNA from DNA. During transcription, the enzyme RNA polymerase binds to a specific region of DNA and synthesizes a complementary RNA strand based on the DNA template. This process is essential for gene expression and protein synthesis in cells. Replication (option A) refers to the process of making copies of DNA, not RNA. Translation (option C) is the process of synthesizing proteins from mRNA, not making copies of RNA from DNA. DNA repair (option D) involves mechanisms that cells use to repair damaged DNA, not the process of making RNA copies from DNA.

4. What does 'mm' stand for in the metric system?

• A. millimeter
• B. megabyte
• C. millipede
• D. metered

Correct answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

5. Which of the following nucleic acids carries the genetic information copied from DNA to the ribosomes?

• A. DNA
• B. mRNA
• C. rRNA
• D. tRNA

Correct answer: B

Rationale: The correct answer is B: mRNA. Messenger RNA (mRNA) is responsible for carrying the genetic information copied from DNA to the ribosomes for protein synthesis. mRNA serves as a temporary copy of the genetic instructions stored in DNA and acts as a messenger between the nucleus and ribosomes in the cytoplasm where protein synthesis occurs. While rRNA (ribosomal RNA) and tRNA (transfer RNA) play essential roles in the process of translation at the ribosomes, mRNA is the nucleic acid directly involved in carrying the genetic code for protein synthesis. Therefore, choices A, C, and D are incorrect as DNA is the original genetic material, rRNA is a component of the ribosomes, and tRNA carries amino acids during protein synthesis, respectively.
