1. Which of the following is true of hypotheses of the form 'All x are y'?

Correct answer: D

Rationale: In hypotheses of the form 'All x are y,' the hypothesis is making a claim that all instances of x also fall under y. Therefore, if something is y but not x, it disproves the hypothesis because it contradicts the assertion that all x are y. Choice A is incorrect because something that is neither x nor y doesn't provide evidence against the hypothesis. Choice B is incorrect because if something is both x and y, it actually supports the hypothesis. Choice C is incorrect as something that is x but not y doesn't disprove the hypothesis, as it could still be consistent with the claim that all x are y.

2. Which of the following statements least supports the argument that the American economy is healthy?

Correct answer: D

Rationale: The correct answer is D because a decrease in the manufacturing sector is usually considered a negative indicator for the economy, as it may suggest a decline in production or demand for goods. Choices A, B, and C all provide positive signs for a healthy economy: an increase in GDP reflects economic growth, low unemployment rates indicate a strong job market, and rising household income signifies improved financial well-being for families.

3. According to the aforementioned passage, what is the speaker's second desire for his time in front of the audience?

Correct answer: B

Rationale: The correct answer is B. The speaker's second desire for his time in front of the audience is for the working man to have a say in the management of the institution designed for his benefit. This is evident from the passage where the speaker emphasizes the importance of the working man having a share in the management of an institution designed for his benefit. Choice A is incorrect because although reading a Christmas story was mentioned as the first desire, it was not the second desire. Choice C is incorrect as the desire mentioned is not about standing in the audience's presence but rather about the working man having a say in the institution. Choice D is incorrect as it does not align with the speaker's second desire as mentioned in the passage.

4. What is a typical characteristic of male cicadas?

Correct answer: C

Rationale: Male cicadas are known for making strident, high buzzing sounds by vibrating two membranes on their abdomen, reaching up to 80 to 100 decibels, similar to the roar of a loud engine. This behavior is distinct to male cicadas and serves as a way to attract females for mating. Choice A is incorrect because it describes physical characteristics of cicadas, not behavior. Choice B is incorrect as it describes the behavior of female cicadas, not males. Choice D is incorrect as it pertains to the behavior of female cicadas after mating, not males.

5. What does the 'nature of the fairy tale genre' refer to in Passage 2?

Correct answer: A

Rationale: The 'nature of the fairy tale genre' in Passage 2 refers to the representation of basic human experiences. The passage emphasizes that fairy tales embody fundamental human desires and fears, portraying characters as either pure good or pure evil and celebrating themes like romance and transformation. This representation of basic human experiences makes fairy tales relatable and universal, resonating with audiences across various cultures and time periods. Choices B, C, and D are incorrect because while they may be elements found in fairy tales, they do not capture the essence of the 'nature of the fairy tale genre' as being rooted in the representation of fundamental human experiences.
