1. What does the word 'composed' mean in the passage on the Water Cycle?

A. To consist of.
B. To create.
C. To separate.
D. To destroy.

Correct answer: A

Rationale: In the context of the Water Cycle, 'composed' means 'to consist of' parts. For instance, water is composed of hydrogen and oxygen atoms. Therefore, the correct meaning of 'composed' in this context is to consist of various components. Choice B, 'To create,' is incorrect as 'composed' refers to the makeup of something rather than the act of making or creating. Choices C and D, 'To separate' and 'To destroy,' are also incorrect as they do not align with the meaning of 'composed' in the passage.

2. What conclusion can a reader draw from this passage?

A. It is advisable to choose unsaturated fats over saturated fats.
B. Saturated fats are more calorically dense than unsaturated fats.
C. Trans fats are more calorically dense than saturated fats.
D. Unsaturated fats are mostly found in animal products.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage is that it is advisable to choose unsaturated fats over saturated fats. The passage emphasizes the health benefits of unsaturated fats, such as lowering cholesterol levels and reducing the risk of heart disease. It also mentions that saturated fats, although not as healthy as unsaturated fats, should still be consumed sparingly. Trans fats are highlighted as the least healthy fats, increasing the risk of heart disease. Choice B is incorrect because the passage does not explicitly compare the caloric density of saturated and unsaturated fats. Choice C is incorrect as the passage does not discuss the caloric density of trans fats in comparison to saturated fats. Choice D is incorrect as the passage states that unsaturated fats are found in sources like olive oil, walnut oil, and avocado oil, not mostly in animal products.

3. What is the main idea of the passage about microbes?

A. Recent discoveries are revealing the critical role of microorganisms in maintaining a properly functioning immune system.
B. The human body is host to a staggering number of microorganisms.
C. Bacteriotherapy reintroduces healthy bacteria into a colon lacking the capability to defend against pathogenic agents.
D. Early research has shown remarkable discoveries in the possibilities of bacteriotherapy.

Correct answer: A

Rationale: The main idea of the passage is that recent discoveries are shedding light on the pivotal role of microorganisms in maintaining a properly functioning immune system. The passage discusses how the human body hosts a wide array of microorganisms, emphasizes the importance of these bacteria in the development of the immune system, and explores the potential applications of bacteriotherapy. Choice A is the correct answer because it accurately reflects the central theme discussed in the passage. Choices B, C, and D are incorrect because they focus on specific details or applications mentioned in the passage, rather than capturing the overarching theme of the critical role of microorganisms in immune system function.

4. What statement about global warming is made in the passage on the Amazon Rainforest?

A. Global warming is caused by deforestation.
B. Global warming is unrelated to deforestation.
C. Global warming is exaggerated.
D. Global warming is not a concern.

Correct answer: A

Rationale: The correct statement about global warming in the passage on the Amazon Rainforest is that it is caused by deforestation. The passage explains that cutting down trees in the rainforest increases the amount of carbon dioxide in the air, leading to global warming. This is supported by the fact that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide a year. Choice B is incorrect as the passage clearly establishes a direct link between deforestation and global warming. Choice C is incorrect as the passage does not suggest that global warming is exaggerated, but rather highlights the harmful effects of deforestation. Choice D is incorrect as the passage emphasizes the serious concern of global warming due to deforestation.
