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 'enlist' as it is used in the second paragraph?

• A. call into service
• B. write down
• C. send away
• D. put across

Correct answer: A

Rationale: In the context of the immune system, 'enlist' means to call into service. Immune cells recruit other cells to fight infection by producing chemicals that regulate their growth, behavior, and direct new recruits to trouble spots. This process is essential for the immune system's defense mechanism. The other choices are incorrect: 'write down' and 'put across' do not capture the action of mobilizing immune cells, and 'send away' is opposite in meaning to what is happening in the immune response.

3. Which statement is not listed as a detail within the passage?

• A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
• B. The signal has a characteristic record called the electrocardiogram.
• C. The 'wave of excitation' starts at the SA node.
• D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.

Correct answer: A

Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.

4. What is the main idea of the passage about Super Foods?

• A. Super foods are low in calories but provide essential nutrients that have enormous health benefits.
• B. U.S. supermarkets should make a point of stocking up on powerful super foods.
• C. Blueberries are a super food that contains a natural inflammatory as well as important vitamins and minerals.
• D. Doctors now believe that daily inclusion of super foods in the diet can reverse the aging process.

Correct answer: A

Rationale: The main idea emphasizes that superfoods are low in calories yet rich in essential nutrients that provide significant health benefits. This statement captures the overall essence of the passage, while the other options focus too narrowly or introduce unsupported claims, making A the correct answer.

5. Throughout this passage the word suit means?

• A. A set of clothing to be worn together
• B. To be convenient or right for
• C. To request or appeal persistently
• D. One of the four categories in a deck of cards.

Correct answer: B

Rationale: In the passage, the word 'suit' is used in the context of card games, specifically in relation to playing cards of the same category. It refers to being convenient or right for a particular purpose in the game of Bridge. The other choices are incorrect because 'suit' in this passage does not refer to a set of clothing (option A), persistent requesting (option C), or one of the four categories in a deck of cards (option D). The passage clearly explains how the term 'suit' is used in the context of playing cards in the game of Bridge.
