1. Which of the following is a property of amphiprotic substances?

• A. React with acids only
• B. React with bases only
• C. Can act as both acids and bases
• D. Are inert in chemical reactions

Correct answer: C

Rationale: The correct answer is C: Can act as both acids and bases. Amphiprotic substances have the ability to donate a proton (act as an acid) or accept a proton (act as a base) depending on the reaction conditions. This dual nature allows them to participate in a wide range of chemical reactions, making them versatile and important in various chemical processes. Choices A and B are incorrect because amphiprotic substances are not limited to reacting with only acids or bases; they can interact with both. Choice D is incorrect because amphiprotic substances are not inert; they actively participate in chemical reactions by donating or accepting protons.

2. Which sentence uses correct punctuation?

• A. I cooked so I could eat dinner.
• B. I cooked so, I could eat dinner.
• C. I cooked so I, could eat dinner.
• D. I cooked, so I could eat dinner.

Correct answer: D

Rationale: The correct answer is sentence D: 'I cooked, so I could eat dinner.' This sentence uses a comma correctly to separate two independent clauses, 'I cooked,' and 'so I could eat dinner.' Choice A is incorrect as it lacks punctuation to separate the clauses properly. Choice B incorrectly uses a comma after 'so,' disrupting the flow of the sentence. Choice C incorrectly places a comma after 'I,' which is not needed in this context.

3. Which of the following statements is FALSE regarding the use of qualitative and quantitative data in scientific research?

• A. Quantitative data is collected through numerical measurements.
• B. Quantitative data is more accurate than qualitative data.
• C. Qualitative data is focused on perspectives and behavior.
• D. Qualitative data is collected through observation and interviews.

Correct answer: B

Rationale: The correct answer is B because quantitative data is not inherently more accurate than qualitative data. Both types of data have their strengths and limitations, and the choice of data type depends on the research question and methodology. Quantitative data is collected through numerical measurements and involves statistical analysis. On the other hand, qualitative data focuses on perspectives, behaviors, and meanings and is typically gathered through observation and interviews. While quantitative data provides numerical precision, qualitative data offers in-depth insights into behaviors and perspectives that cannot be quantified, making them equally valuable in scientific research.

4. Which literary device is primarily used in the passage when discussing the transition from water to air?

• A. Metaphor
• B. Simile
• C. Alliteration
• D. Hyperbole

Correct answer: A

Rationale: The correct answer is A: Metaphor. The transition from water to air is described metaphorically in the passage, highlighting the significant change in the insects' environment. The passage discusses how certain insects start their life underwater and then transition to the air, symbolizing a transformation. This metaphorical description enhances the reader's understanding of the insects' life cycle. Choice B, Simile, is incorrect because a simile involves comparing two unlike things using 'like' or 'as,' which is not evident in the passage. Choices C and D, Alliteration and Hyperbole, are incorrect as they are not used in the passage to describe the transition from water to air. Therefore, the best literary device used in this context is a metaphor.

5. 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.
