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

A. Something that is neither x nor y disproves the hypothesis.
B. Something that is both x and y disproves the hypothesis.
C. Something that is x but not y disproves the hypothesis.
D. Something that is y but not x disproves the hypothesis.

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.

B. Unemployment is the lowest it has been in over a decade due to job creation.
C. Average household income just hit a historical high point.
D. The output of the United States' manufacturing sector decreased.

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?

A. To read a Christmas story
B. For the working man to have a say in the management of the institution designed for his benefit
C. To have an opportunity to stand in their presence
D. For the life of the institution to be essential to the audience as a whole

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.

A. They have short antennae and wide-set eyes.
B. They respond with a clicking sound when ready to mate.
C. They make strident, high buzzing sounds by vibrating two membranes on their abdomen.
D. They deposit eggs into the bark after mating.

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.

A. The representation of basic human experience
B. Good characters being pure good and bad characters being pure evil
C. Different cultures coming up with similar versions of the same story

Correct answer: A

Rationale: The 'nature of the fairy tale genre' in Passage 2 refers to the representation of basic human experiences.

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.
