1. What is the main reason the author wrote the passage about the Electoral College?

• A. To criticize the complexity of the Electoral College.
• B. To explain how the Electoral College works.
• C. To advocate for abolishing the Electoral College.
• D. To promote the benefits of the Electoral College.

Correct answer: B

Rationale: The correct answer is B. The passage primarily aims to explain how the Electoral College functions in U.S. elections. It provides details on how the Electoral College operates, including the allocation of electoral votes based on states' representation in Congress, the role of senators and representatives, and how electoral votes are cast during presidential elections. Choices A, C, and D are incorrect because the passage does not criticize, advocate for abolishing, or promote the benefits of the Electoral College. Instead, it focuses on clarifying its mechanism.

2. An object with a charge of 3 μC is placed 30 cm from another object with a charge of 2 μC. What is the magnitude of the resulting force between the objects?

• A. 0.6 N
• B. 0.18 N
• C. 180 N
• D. 9 × 10−12 N

Correct answer: B

Rationale: To find the magnitude of the resulting force between two charges, we use Coulomb's Law: F = k × (|q1 × q2|) / r² Where: F is the force k is Coulomb’s constant (8.99 × 10⁹ N·m²/C²) q1 and q2 are the charges r is the distance between the charges Plugging in the values: F = (8.99 × 10⁹) × (3 × 10⁻⁶) × (2 × 10⁻⁶) / (0.3)² = 0.18 N. Therefore, the magnitude of the resulting force is 0.18 N.

3. The new mother wanted to use cloth diapers rather than disposables.

• A. Close
• B. Clothing
• C. Cloth
• D. Clothes

Correct answer: C

Rationale: The correct choice is C. Cloth because in the sentence, the new mother expressed a preference for using cloth diapers over disposables. 'Cloth' refers to a type of diaper material, and it makes sense in the context of the sentence. Choice A, 'Close,' is incorrect as it does not relate to the type of diapers being discussed. Choice B, 'Clothing,' is incorrect as it refers to garments worn on the body, not diapers. Choice D, 'Clothes,' is also incorrect as it is used for general garments, not specific to diapers.

4. 72 chromosomes undergo meiosis. How many chromosomes will be in each gamete?

• A. 18
• B. 36
• C. 72
• D. 144

Correct answer: A

Rationale: During meiosis, the number of chromosomes is halved in each gamete. Since 72 chromosomes undergo meiosis, each gamete will contain half of that number, which is 36 chromosomes. Therefore, the correct answer is 18 chromosomes in each gamete. Choice B (36 chromosomes) is incorrect because it represents the total number of chromosomes that undergo meiosis, not the number in each gamete. Choice C (72 chromosomes) is incorrect as it represents the initial number of chromosomes, not the number in each gamete after meiosis. Choice D (144 chromosomes) is incorrect as it doubles the initial number of chromosomes, which is not the outcome of meiosis.

5. Where is the site of cellular respiration in eukaryotic cells?

• A. Nucleus
• B. Chloroplasts
• C. Mitochondria
• D. Ribosomes

Correct answer: C

Rationale: The correct answer is C: Mitochondria. Mitochondria are often referred to as the powerhouse of the cell because they are responsible for cellular respiration in eukaryotic cells. During cellular respiration, mitochondria generate energy in the form of ATP. Choices A, B, and D are incorrect. The nucleus is the organelle that houses the cell's genetic material, chloroplasts are responsible for photosynthesis in plant cells, and ribosomes are involved in protein synthesis, not cellular respiration.
