1. What conclusion can be drawn about the article?

• A. The author explains differences in eating methods.
• B. Eating habits vary across different cultures.
• C. Space travel has posed challenges for eating habits.
• D. Chopsticks are more suitable than forks for space travel.

Correct answer: A

Rationale: The correct answer is A. The passage discusses different eating methods in various cultures, focusing on their differences. The author describes the development of cutlery in European cultures, the use of chopsticks in China, and how space travel has influenced eating tools for astronauts. Choice B is incorrect because the passage emphasizes the differences rather than the similarities in eating habits across cultures. Choice C is partially supported by the passage as it mentions that space travel has created new challenges for consuming food, but it is not the main conclusion of the article. Choice D is not directly supported by the passage as it discusses the challenges of using chopsticks and forks in space rather than stating that chopsticks are superior to forks.

2. What does the word 'obligatory' mean in the context of the passage on Daylight Savings Time?

• A. Approved.
• B. Sparse.
• C. Requisite.
• D. Aberrant.

Correct answer: C

Rationale: In the passage, Daylight Savings Time is presented as something that must be done by law, making it a requirement or something obligatory. 'Requisite' fits this meaning. 'Approved' (choice A) does not convey the sense of necessity as 'obligatory' does. 'Sparse' (choice B) means thinly dispersed and does not relate to the context. 'Aberrant' (choice D) means deviating from the norm, which is not applicable in this context.

3. 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.

4. Another word for CONSISTENCY is?

• A. Appearance
• B. Volatility
• C. Thickness
• D. Color

Correct answer: C

Rationale: Consistency refers to the quality of staying the same in behavior or level. Thickness is a synonym for consistency as it implies a state of being dense, compact, or solid throughout, which aligns with the idea of staying the same. Conversely, appearance, volatility, and color do not directly relate to the concept of consistency. 'Appearance' refers to how something looks, 'volatility' refers to how easily something changes, and 'color' refers to the hue or shade of something, none of which capture the essence of consistency.

5. How is pepsin utilized by the body?

• A. To break down proteins
• B. To break down starches
• C. To emulsify fats and oils
• D. To absorb water and nutrients

Correct answer: A

Rationale: Pepsin is an enzyme produced in the stomach that is essential for breaking down proteins during digestion. It functions by breaking down large protein molecules into smaller peptides, which are further broken down into amino acids for absorption in the intestines. Therefore, option A, 'To break down proteins,' is the correct answer. Choices B, C, and D are incorrect as they do not align with the specific function of pepsin in the body.
