1. 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.

2. Why does the author mention 'impact craters' in line 16?

A. To explain the corrosive effects of atmospheric weathering
B. To explain why the Moon has no plant life because of meteorites
C. To show the result of the Moon not having an atmosphere
D. To show the result of the Moon not having active tectonic or volcanic activity

Correct answer: C

Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.

3. What is the main idea of this passage?

A. The water cycle consists of precipitation, evaporation, and condensation
B. Water cycle components include only evaporation and condensation
C. The water cycle includes precipitation, runoff, evaporation, and condensation
D. The water cycle happens in the atmosphere only

Correct answer: A

Rationale: The correct answer is A: 'The water cycle consists of precipitation, evaporation, and condensation.' The passage explains the stages of the water cycle, which are precipitation (rain, snow, sleet, or hail), runoff, evaporation, and condensation. Choice B is incorrect because the water cycle involves more than just evaporation and condensation. Choice C is incorrect as it includes an additional element, runoff, not mentioned as a primary component of the water cycle in the passage. Choice D is incorrect as the water cycle involves processes both in the atmosphere and on the ground.

4. What is the overall tone of the essay about A Short History of the CDC?

A. Appreciative.
B. Awestruck.
C. Somber.
D. Disheartened.

Correct answer: A

Rationale: The tone of the essay is appreciative, reflecting a recognition of the CDC's historical contributions to public health. The passage highlights the organization's evolution and its significant impact on disease control and prevention, suggesting a positive and respectful view of its work over the years, making A the correct choice.

5. What is the meaning of the word delicate as used in the first paragraph?

A. Subtle
B. Fragile
C. Refined
D. Intricate

Correct answer: D

Rationale: In the context of microsurgery, the word 'delicate' refers to the intricate, precise, and fine nature of surgeries performed using microscopy. These surgeries require intricate attention to detail and precision due to the small and delicate structures involved, making 'intricate' the most appropriate synonym. 'Subtle' implies understated or not obvious, 'fragile' suggests easily broken or damaged, and 'refined' refers to something developed or improved over time, none of which fully capture the detailed and precise nature of microsurgery. Therefore, 'intricate' is the correct answer.
