1. 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.
2. What is the meaning of the word touted as used in the first paragraph about Aromatherapy?
- A. Revealed.
- B. Glorified.
- C. Overcome.
- D. Deceived.
Correct answer: B
Rationale: "Touted" in this passage means glorified or praised, indicating how aromatherapy has been widely promoted as beneficial. The context implies that while it is marketed positively, recent studies have called its effectiveness into question. Other choices do not capture this promotional aspect accurately, making B the best fit.
3. What is the main idea of the passage about MRSA?
- A. Methicillin-resistant Staphylococcus aureus (MRSA) is a significant problem both within and outside of hospitals, and there are ways to mitigate the risk.
- B. A new textile made of nanomaterials could significantly reduce the spread of hospital-associated MRSA infections.
- C. There are multiple strains of MRSA, and they pose various risks beyond just fatality.
- D. MRSA is a significant problem both within and outside of hospitals, but there are ways to mitigate the risk.
Correct answer: D
Rationale: The main idea of the passage is that MRSA is a significant issue both within and outside of hospitals. It highlights the challenges posed by MRSA, including its resistance to antibiotics, high mortality rates, and widespread presence in various settings. While the development of new technologies like nanomaterial textiles shows promise in reducing hospital-associated MRSA, the passage also emphasizes the importance of practicing good hygiene to prevent community-associated MRSA infections. Choices A, B, and C are incorrect because they do not capture the comprehensive overview of MRSA provided in the passage. Choice A encompasses the main idea by emphasizing the significance of MRSA and ways to mitigate the risk. Choice B focuses on a specific solution rather than the broader issue of MRSA. Choice C is incorrect as it oversimplifies the risks associated with MRSA strains by only mentioning fatality.
4. The passage mentions all of the following claims for the health benefits of super foods EXCEPT ___________.
- A. lowering cholesterol
- B. stabilizing insulin levels
- C. building muscle mass
- D. reducing blood pressure
Correct answer: C
Rationale: The passage discusses various health benefits of superfoods, such as lowering cholesterol, stabilizing insulin levels, and reducing blood pressure. However, it does not mention anything about building muscle mass, making C the correct choice as it identifies the claim that is not supported by the passage.
5. What is the meaning of the word instill as used in the second paragraph of the passage?
- A. Impart
- B. Propagandize
- C. Demand
- D. Create
Correct answer: A
Rationale: The correct answer is A: 'Impart.' In the context of the passage, 'instill' means to impart important lessons about maintaining good health, staying fit, and keeping weight under control. This word choice is appropriate as it aligns with the idea of teaching and passing on knowledge. Choice B, 'Propagandize,' is incorrect as it implies spreading biased or misleading information, which is not the intended meaning in this context. Choice C, 'Demand,' is incorrect as it does not capture the concept of teaching or passing on lessons. Choice D, 'Create,' is also incorrect as it does not convey the idea of imparting knowledge or lessons, which is the central meaning of 'instill' in this context.
