1. Which of these objects has the greatest momentum?

• A. A 1,250-kg car moving at 5 m/s
• B. An 80-kg person running at 4 m/s
• C. A 10-kg piece of meteorite moving at 600 m/s
• D. A o.5-kg rock moving at 40 m/s

Correct answer: A

Rationale: Momentum is the product of mass and velocity. The car has the highest momentum because it has the largest mass and a significant velocity.

2. Which of the following is not part of the central nervous system?

• A. Retina
• B. Spinal cord
• C. Brain
• D. Heart

Correct answer: B

Rationale: The central nervous system consists of the brain and spinal cord, which are responsible for processing and coordinating information. The retina is part of the eye, while the heart is part of the circulatory system. Therefore, the correct answer is 'Spinal cord' as it is not part of the central nervous system.

3. If you are an assiduous worker, you are probably ____?

• A. Lazy
• B. Industrious
• C. Inconsistent
• D. Procrastinating

Correct answer: B

Rationale: The correct answer is B. If someone is described as assiduous, it means they are diligent, hardworking, and persistent in their efforts. This aligns with the trait of being 'Industrious.' Choices A, C, and D are incorrect because being lazy, inconsistent, or procrastinating are the opposite characteristics of someone who is assiduous.

4. 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.

5. During which phase of cell division do the chromosomes replicate?

• A. Prophase
• B. Interphase
• C. Anaphase
• D. Telophase

Correct answer: B

Rationale: Chromosomes replicate during the interphase of the cell cycle. Interphase is the phase where the cell prepares for division by undergoing various activities such as growth, DNA replication, and protein synthesis. During DNA replication in interphase, each chromosome in the cell is duplicated to form two sister chromatids, which are then separated during cell division. Prophase is the phase where the chromosomes condense, and the nuclear envelope breaks down. Anaphase is the phase where sister chromatids are pulled apart towards opposite poles of the cell. Telophase is the phase where the nuclear envelope reforms, and chromosomes begin to decondense.
