1. What is the main idea of the passage on Daylight Savings Time?

A. Daylight Savings Time helps save energy.
B. Daylight Savings Time is unnecessary and outdated.
C. Daylight Savings Time is a law to conserve energy during wars.
D. Daylight Savings Time was first implemented in Germany.

Correct answer: A

Rationale: The correct answer is A: "Daylight Savings Time helps save energy." The passage explains how Daylight Savings Time is implemented to take advantage of more daylight, which results in energy savings. By adjusting clocks ahead in spring, people can make use of additional daylight in the evenings, leading to reduced energy consumption. This measure was introduced to address energy crises and has been shown to save significant amounts of energy. Choice B is incorrect as the passage does not portray Daylight Savings Time as unnecessary or outdated; instead, it highlights its benefits. Choice C is partially correct but not the main idea of the passage, as saving energy is the primary focus. Choice D is mentioned in the passage but is not the main idea; the main idea is about the purpose and benefits of Daylight Savings Time.

2. Choose the best summary of the passage about microbes.

A. Scientists have discovered the importance of certain bacteria for a well-functioning immune system, especially in defending against pathogens. The colonization of microbes in the body begins at birth, with the immune system relying on these bacteria for proper function.
B. The passage discusses the role of bacteria in the development of the human immune system. It highlights that the body supports various microorganisms crucial for immunity, starting from birth. The presence of harmless bacteria is essential for the immune system to work effectively.
C. The body hosts a vast number of microorganisms critical for immune system development. Harmless bacteria are necessary for the immune system to defend against pathogens effectively. Early research shows promising results in fecal bacteriotherapy for restoring the immune system's ability to fight off harmful invaders.
D. Microbes play a pivotal role in human health, particularly in immune system development. The introduction of healthy bacteria is essential for the immune system to function correctly. Fecal bacteriotherapy is a novel approach to reintroducing beneficial bacteria into a compromised colon to enhance immune response.

Correct answer: C

Rationale: The correct answer is C. The passage emphasizes the importance of certain bacteria for a properly functioning immune system. It discusses how harmless bacteria play a crucial role in defending the body against pathogens. Choice A is incorrect as it focuses on the immune system's response to certain types of bacteria in lower organisms, not the overall importance of bacteria for immunity. Choice B is incorrect as it mainly discusses bacteriotherapy in relation to the reconstruction of a damaged colon, rather than the broader role of bacteria in immune system health. Choice D is incorrect as it only talks about the process of replacing harmful bacteria with harmless ones, missing the key point about the necessity of certain bacteria for immune system function.

3. What was the author's motive for writing the paragraph?

A. Encourage overeating.
B. Criticize healthy eating habits.
C. Urge self-control.
D. Promote exercise.

Correct answer: C

Rationale: The author's motive for writing the paragraph is to urge self-control. The text emphasizes the importance of moderation in food and drink consumption to avoid serious physical and mental health problems. It highlights the negative consequences of overeating and alcohol abuse, pointing out the strain on the heart, diabetes risk, shortened lifespan, and emotional eating habits. By discussing the issues related to overconsumption, the author aims to promote self-control and responsible habits. Choices A, B, and D are incorrect because the paragraph focuses on advocating moderation and self-discipline rather than encouraging overeating, criticizing healthy eating habits, or promoting exercise.

4. 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.

5. What is the meaning of the word 'abstain' as used in the last paragraph?

A. Dishonor
B. Go without
C. Connect to
D. Liberate

Correct answer: B

Rationale: In the context of the passage, 'abstain' means to refrain from or go without. The passage discusses the challenges of treating individuals with both eating disorders and substance abuse issues. It mentions that while treatment for addiction involves abstinence, it is not possible to completely abstain from food. This highlights the meaning of 'abstain' as 'go without' in this context. The other choices are incorrect: 'Dishonor' does not relate to abstain, 'Connect to' is not synonymous with abstain, and 'Liberate' does not align with the context of the passage.
