1. 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.
2. Why does the author mention 'impact craters' in line 16?
- A. To explain the corrosive effects of atmospheric weathering
- B. To explain why the Moon has no plant life because of meteorites
- C. To show the result of the Moon not having an atmosphere
- D. To show the result of the Moon not having active tectonic or volcanic activity
Correct answer: C
Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.
3. Why did Strauss set up a net during the construction of the Golden Gate Bridge?
- A. For suspension
- B. For balance
- C. For aesthetics
- D. For safety
Correct answer: D
Rationale: Strauss set up a net to ensure the safety of the workers in case of falls during the construction of the Golden Gate Bridge. Safety nets were essential to protect the workers from potential accidents or falls while working on the bridge. Choice A ('For suspension') is incorrect as safety nets were not used for suspension purposes but rather for worker safety. Choice B ('For balance') is incorrect as the balance of the bridge was maintained by other construction elements, not safety nets. Choice C ('For aesthetics') is incorrect as safety nets are not related to the visual appearance of the bridge but rather to the protection of the workers.
4. Which claim from the passage best describes the benefits of nanotechnology?
- A. Scientists can develop novel technologies and products.
- B. Nanotechnology is defined as the understanding and control of matter at dimensions of roughly 1 to 100 nanometers.
- C. The different colors can be used in simple medical tests to indicate infection or disease.
- D. Unique properties of materials emerge.
Correct answer: D
Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.
5. The information presented is
- A. Balanced in its view of public speaking.
- B. Favoring people with low-pitched voices.
- C. Slanted against people with piercing voices.
- D. Neutral toward both high- and low-pitched voices.
Correct answer: C
Rationale: The correct answer is C. The paragraph is biased against people with piercing or harsh voices, suggesting they are less desirable as public speakers, newscasters, or political candidates. The text explicitly mentions that harsh voice qualities, like being shrill, grating, hard, piercing, brassy, loud, or nasal, are undesirable and may make people uncomfortable when speaking. It also highlights that tension leading to harsh voice qualities is more common in higher-pitched voices, which are typically associated with women, making them less preferred for public speaking roles. Choices A, B, and D are incorrect because the text does not suggest a balanced view, favor low-pitched voices, or maintain neutrality towards both high- and low-pitched voices; instead, it emphasizes the negative impact of harsh and piercing voices.
