1. The beautiful flowers brightened the room. Which word is the adverb form of the adjective 'beautiful'?

• A. beautiful
• B. beautifully
• C. beautification
• D. beautify

Correct answer: B

Rationale: In the sentence, 'beautiful' is used as an adjective to describe the flowers. To transform the adjective 'beautiful' into an adverb, you add '-ly,' resulting in 'beautifully.' Adverbs modify verbs, adjectives, or other adverbs, offering more details on how an action is performed. Choice A ('beautiful') is the original adjective form and not the adverb form. Choice C ('beautification') is a noun, not an adverb. Choice D ('beautify') is a verb, not an adverb.

2. Acids are generally characterized by a sour taste and the ability to:

• A. Turn litmus paper red
• B. Conduct electricity in solution
• C. Neutralize bases
• D. React explosively with metals

Correct answer: C

Rationale: Acids are known for their sour taste and their ability to neutralize bases, which is a defining characteristic of their acidic nature. When acids neutralize bases, salts and water are formed, highlighting the unique property of acids. The other options are incorrect: Option A, 'Turn litmus paper red,' is a test for acidity but not a defining characteristic of acids; Option B, 'Conduct electricity in solution,' pertains to the electrolytic properties of acids rather than their defining trait; Option D, 'React explosively with metals,' is not a general characteristic of acids. Therefore, the correct feature associated with acids is their capability to neutralize bases, making option C, 'Neutralize bases,' the correct answer.

3. Which of the following components is found in DNA?

• A. Uracil
• B. Deoxyribose
• C. Guanine
• D. Phosphate group

Correct answer: B

Rationale: The correct answer is B: Deoxyribose. DNA is composed of nucleotides containing deoxyribose sugar, phosphate group, and nitrogenous bases (adenine, thymine, guanine, and cytosine). Deoxyribose is the sugar component specific to DNA, while ribose is found in RNA. Guanine (choice C) is a nitrogenous base present in both DNA and RNA. Uracil (choice A) is a nitrogenous base specific to RNA, replacing thymine found in DNA. The phosphate group (choice D) is an essential part of nucleotides in both DNA and RNA, providing the backbone structure for the nucleic acid chains.

4. Which of the following best describes the peer review process?

• A. It guarantees acceptance of all papers
• B. It requires time and attention to complete
• C. It is a straightforward task
• D. It enables instant publication of papers

Correct answer: B

Rationale: The correct answer is B because the peer review process demands time and attention for a thorough evaluation by experts. Choice A is incorrect because peer review does not guarantee acceptance of all papers; rather, it aims to assess the quality and validity of research. Choice C is incorrect as peer review is not always a simple or straightforward task due to the detailed scrutiny involved. Choice D is incorrect because peer review does not allow papers to be published instantly; instead, it involves a rigorous evaluation process before publication.

5. The Becquerel (Bq) is the designated unit for quantifying:

• A. Electron volt (eV) measurements of energy
• B. Radioactivity
• C. Electric charge (Coulombs)
• D. Force (Newtons)

Correct answer: B

Rationale: The Becquerel (Bq) is the unit used to measure radioactivity, specifically the activity of a quantity of radioactive material. It represents the number of radioactive disintegrations or transformations per unit of time. Choice A, electron volt (eV), is a unit of energy, not radioactivity. Choice C, electric charge (Coulombs), is measured in Coulombs, not Becquerels. Choice D, force (Newtons), is a unit of force, not radioactivity. Therefore, the correct answer is B.
