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.

2. Which option best describes the use of the spider in the poem?

A. Idiom
B. Haiku
C. ABBA rhyming convention
D. Simile

Correct answer: D

Rationale: The correct answer is D, 'Simile.' In the poem, the speaker compares the spider to an artist using 'as,' indicating a simile. A simile is a figure of speech that compares two different things using 'like' or 'as.' Choices A, B, and C are incorrect. An idiom is a phrase with a figurative meaning different from its literal meaning, a haiku is a form of Japanese poetry, and ABBA rhyming convention refers to a specific rhyme scheme commonly found in poetry, none of which apply to the comparison of the spider to an artist in the poem.

3. How did Hedy Lamarr contribute significantly to the advancement of technology?

A. The technology of the era wasn't advanced enough to easily implement Lamarr's system
B. She collaborated with the science engineering team employed by Howard Hughes, the aviation tycoon
C. She had several failed inventions, such as an improved traffic light and a carbonated drink
D. Her work led to the future development of cellular phones, Bluetooth, and Wi-Fi.

Correct answer: D

Rationale: The correct answer is D because Hedy Lamarr's invention of a frequency-hopping system, along with George Antheil, laid the foundation for technologies like cellular phones, Bluetooth, and Wi-Fi. This significant contribution revolutionized communication technology. Choice A is incorrect because it focuses on the limitations of the era's technology rather than Lamarr's contributions. Choice B is incorrect as it briefly mentions her collaboration but does not directly relate it to technological advancements. Choice C is incorrect as it highlights her failed inventions, which are not indicative of her significant contributions to technology.

4. What is a typical characteristic of male cicadas?

A. They have short antennae and wide-set eyes.

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.

Therefore, the reader can conclude that the author is likely interested in cicadas and their natural history, indicating that they go to the theater as often as possible. Choice A is incorrect because there is no evidence regarding the author being overly emotional. Choice B is incorrect as there is no mention of the author's preference for concerts. Choice D is incorrect as the passage does not provide any information about the author enjoying theater decor.
