In the context of the passage, 'accommodate' means to
- A. Arrange lodging for
- B. Contain
- C. Make allowances for
- D. Excuse
Correct Answer: C
Rationale: In this context, 'accommodate' means to make allowances for different focal points of vision. The passage explains that the function of the lens is to adjust for different focal points so that sensory data can be correctly directed to the retina for interpretation into images by the brain. This aligns with the meaning of 'make allowances for' as it indicates adapting to or accommodating different needs or requirements. Choices A, B, and D are incorrect because in the context of the passage, 'accommodate' specifically refers to adjusting for different focal points of vision rather than arranging lodging, containing, or excusing.

Why did Macmillan add iron rims to the tires of his bicycle?
- A. Increase the weight of the bicycle.
- B. Enhance the durability of the tires.
- C. Reduce the bumpiness of the ride.
- D. Decrease the level of fatigue during the ride.
Correct Answer: B
Rationale: Macmillan added iron rims to his bicycle tires to enhance their durability and make them last longer. This innovation aimed to prevent the tires from getting worn down quickly. Adding weight to the bicycle (Choice A) was not the purpose of adding iron rims. While adding iron rims could potentially reduce the bumpiness of the ride (Choice C) by providing more stability, the main objective was to improve tire longevity. Similarly, reducing the level of fatigue during the ride (Choice D) was not the primary reason for adding iron rims.
Which of the following would be the best title for this passage?
- A. Bicycles are better.
- B. A ride through the history of bicycles.
- C. Cycle your way to fitness.
- D. The popularity of bicycles.
Correct Answer: B
Rationale: The best title for this passage would be 'A ride through the history of bicycles' as it provides a comprehensive overview of the historical development of bicycles from their invention to modern times. Choice A, 'Bicycles are better,' is incorrect as it does not capture the essence of the passage, which focuses on the history and evolution of bicycles rather than their superiority. Choice C, 'Cycle your way to fitness,' is misleading as the passage does not primarily discuss the fitness aspect of cycling but instead focuses on the evolution of bicycle design. Choice D, 'The popularity of bicycles,' is too narrow as it only touches on one aspect mentioned briefly in the passage, while the passage covers a broader historical perspective.
The word 'massive' in line 4 is closest in meaning to?
- A. Dense
- B. Impressive
- C. Huge
- D. Unavoidable
Correct Answer: C
Rationale: In the context of the passage, 'massive' is used to describe the size of the collision that formed the Moon, indicating something very large or huge. While 'dense' means closely compacted, 'impressive' means evoking admiration, 'huge' is the closest synonym to 'massive' in this context. 'Unavoidable' does not convey the same meaning as 'massive' in this sentence, making it incorrect.
Which of the following describes the purpose of the passage?
- A. To describe the causes of cystic fibrosis
- B. To explain how cystic fibrosis is passed down through families
- C. To provide an overview of CF and how it is inherited
- D. To review why some Americans have CF, but others do not
Correct Answer: C
Rationale: The correct answer is C. The passage aims to provide an overview of cystic fibrosis (CF) and how it is inherited. It explains that CF is passed down through families due to a defective gene, detailing how this gene affects the body and who is most commonly affected by the disease. Choices A, B, and D are incorrect because the passage does not solely focus on describing the causes of CF, explaining how it is passed down through families, or reviewing why some Americans have CF while others do not. Instead, it provides a broader perspective on CF and its inheritance.
What is the passage primarily about?
- A. What we know about the Moon and its differences from Earth
- B. A comparison of the Moon and Earth
- C. The Moon's effect on Earth
- D. The origin of the Moon
Correct Answer: A
Rationale: The correct answer is A: 'What we know about the Moon and its differences from Earth.' The passage discusses various aspects of the Moon, including its origin, gravitational influence on Earth, physical characteristics, lack of atmosphere, and surface features. It provides insights into what humans know about the Moon and highlights its differences from Earth. Choice B is incorrect because while the passage does compare certain aspects of the Moon and Earth, it primarily focuses on the Moon itself rather than a direct comparison. Choice C is incorrect as the passage briefly mentions the Moon's effect on Earth in relation to tides but does not primarily focus on this aspect. Choice D is incorrect as the origin of the Moon is mentioned in the passage, but it is not the primary focus of the text.
