1. What is the meaning of the word diligent as used in the last paragraph about Sickle-Cell Anemia?

A. Dispersed.
B. Incensed.
C. Painstaking.
D. Demanding.

Correct answer: C

Rationale: In the context of sickle-cell anemia, diligent means painstaking, indicating the careful and thorough approach required to manage the disease. The passage highlights the challenges of managing the symptoms of sickle-cell anemia and the need for meticulous and conscientious care. Choices A, B, and D are incorrect. 'Dispersed' and 'Incensed' do not align with the meaning of diligent in this context. 'Demanding' does not capture the essence of the careful and thorough care needed to manage the disease.

2. 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.

3. The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?

A. A carpenter uses wood glue to fix a broken cabinet.
B. A student buys a new notebook for upcoming classes.
C. A chef sharpens knives before starting to cook.
D. An athlete stretches before a game to avoid a potential injury.

Correct answer: D

Rationale: The correct analogy for the role of corrective lenses in helping aging eyes can be compared to an athlete stretching before a game. Just as stretching prepares an athlete's body to perform optimally and avoid injury during a game, corrective lenses help aging eyes adjust and focus properly due to the hardening and loss of elasticity in the eye lens. Choices A, B, and C do not align with the concept of preparing or adjusting to address a specific issue, unlike the use of corrective lenses for aging eyes.

4. What is implied about the rainforest's role in global climate?

A. The rainforest has little impact on the climate.
B. The rainforest plays a crucial role in regulating the climate.
C. The rainforest is mainly important for biodiversity.
D. The rainforest's destruction has no global consequences.

Correct answer: B

Rationale: The rainforest plays a crucial role in regulating the global climate by absorbing carbon dioxide. The extract highlights the fact that trees take in carbon dioxide and give off oxygen. When trees are cut down, the amount of carbon dioxide increases, contributing to global warming. This emphasizes the significant impact of rainforests on the climate. Choice A is incorrect as the extract clearly states the importance of rainforests in absorbing carbon dioxide. Choice C, while true, is not directly related to the implied role of rainforests in regulating the climate. Choice D is also incorrect as the destruction of rainforests does have global consequences, such as contributing to global warming.

5. Which of the following is not listed as a detail in the passage about Yoga?

A. Improved circulation.
B. Strengthening of core muscles.
C. Stress reduction.
D. Fortification of immune system.

Correct answer: D

Rationale: The passage outlines several benefits of yoga, such as improved circulation, strengthened core muscles, and reduced stress. However, it does not mention the fortification of the immune system, which is not discussed in the context of the benefits of yoga. This makes D the correct answer, as it is the only option not supported by the passage.
