1. What word is best to substitute for the underlined words in the following sentence? The children loved having their photographs taken.

• A. its
• B. their
• C. they
• D. his

Correct answer: B

Rationale: The correct word to substitute for the underlined words 'the children' in the sentence would be 'their' to ensure clarity and proper possessive form. Using 'their' makes it clear that the photographs belong to the children. Choice A 'its' is incorrect as it refers to singular possession. Choice C 'they' is a pronoun and does not indicate possession. Choice D 'his' is incorrect as it is singular and refers to a male possessive form, which does not match the plural 'children' in the sentence.

2. Which might be a good title for this passage about Barefoot Running?

• A. Everyone Should Run Barefoot
• B. How to Prevent Running Injuries
• C. Modern Road Surfaces Versus Barefoot Running
• D. The Debate over Barefoot Running

Correct answer: D

Rationale: The title 'The Debate over Barefoot Running' captures the main discussion in the passage.

3. During protein synthesis, what process creates a complementary strand of RNA from a DNA template?

• A. Transcription
• B. Translation
• C. Transformation
• D. Replication

Correct answer: A

Rationale: The correct answer is 'Transcription.' During protein synthesis, transcription is the process that creates a complementary RNA strand from a DNA template. This process involves the synthesis of mRNA using DNA as a template. Choice B, 'Translation,' is incorrect as it is the process where the genetic code carried by mRNA is decoded to produce a specific polypeptide chain. Choice C, 'Transformation,' is not related to the synthesis of RNA from a DNA template. Choice D, 'Replication,' is the process of copying DNA to produce an identical DNA molecule, not RNA.

4. Which of these represents a strong acid?

• A. CH₃COOH
• B. H₂SO₄
• C. NH₃
• D. KOH

Correct answer: B

Rationale: Among the options provided, H₂SO₄ (sulfuric acid) represents a strong acid. Strong acids completely ionize in water to produce a high concentration of H+ ions. Sulfuric acid is a strong acid known for its ability to dissociate almost completely in water, making it a strong acid. Choice A, CH₃COOH (acetic acid), is a weak acid that only partially dissociates in water. Choices C and D, NH₃ (ammonia) and KOH (potassium hydroxide), are bases and not acids.

5. What is the perimeter of a square with a side length of 5 meters?

• A. 15 meters
• B. 20 meters
• C. 25 meters
• D. 30 meters

Correct answer: B

Rationale: The formula to calculate the perimeter of a square is P = 4s, where P is the perimeter and s is the length of a side. Given that the side length is 5 meters, the perimeter is 4 * 5 = 20 meters. Therefore, the correct answer is B. Choices A (15 meters), C (25 meters), and D (30 meters) are incorrect as they do not correctly apply the formula to calculate the perimeter of a square.
