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 conclusion can the reader draw after reading the passage about The Sleep Workout?

• A. Getting uninterrupted sleep is more important than getting enough sleep.
• B. Insufficient sleep may result in an increased risk for obesity.
• C. Human growth hormone is not essential for muscle development.
• D. Leptin is essential for building muscle.

Correct answer: B

Rationale: The correct answer is B because the passage highlights that insufficient sleep could lead to an increased risk of obesity. The passage emphasizes the importance of uninterrupted sleep in muscle development and mentions that inadequate sleep is linked to lowered levels of leptin, a hormone that controls appetite. This imbalance in leptin due to lack of sleep can lead to increased cravings for carbohydrates, contributing to obesity. Choice A is incorrect as the passage stresses the significance of both uninterrupted sleep and getting enough sleep for muscle growth. Choice C is incorrect because the passage clearly states that human growth hormone (HGH) is essential for muscle development. Choice D is incorrect as leptin is not essential for building muscle but is mentioned in the passage as a hormone related to controlling appetite and its link to inadequate sleep and obesity.

3. Which might be a good title for the passage about Barefoot Running?

• A. Everyone Should Run Barefoot.
• B. How to Prevent Running Injuries.
• C. Modern Road Surfaces Versus Barefoot Running.
• D. The Debate over Barefoot Running.

Correct answer: D

Rationale: The title 'The Debate over Barefoot Running' captures the main discussion in the passage.

4. What statement about jetlag can be inferred from the passage on Daylight Savings Time?

• A. Jetlag is caused by flying at high speeds.
• B. Jetlag is caused by moving between time zones.
• C. Jetlag is unrelated to time zone changes.
• D. Jetlag is a myth.

Correct answer: B

Rationale: The correct answer is B: 'Jetlag is caused by moving between time zones.' The passage explains that jetlag occurs when moving suddenly from one time zone to another, such as when flying from Asia to North America. This disrupts the body's internal clock, leading to symptoms like tiredness and sleep disturbances. Choice A is incorrect as jetlag is not attributed to high-speed travel but to time zone changes. Choice C is incorrect as the passage clearly links jetlag to changes in time zones. Choice D is incorrect as jetlag is a real phenomenon experienced by individuals who travel across different time zones.

5. What is the meaning of the phrase 'phased in' as it is used in the third paragraph?

• A. stunned into silence
• B. confused
• C. implemented in stages
• D. legalized

Correct answer: C

Rationale: 'Phased in' means implemented in stages, referring to the gradual implementation of good manufacturing practices. In the provided extract, it mentions that requirements for good manufacturing practices (GMPs) were phased in for small manufacturers through 2010, indicating a gradual implementation process. The other choices, 'stunned into silence,' 'confused,' and 'legalized,' do not accurately reflect the meaning of 'phased in' in the context of the paragraph.
