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 of the following represents an opinion statement on the part of the author?

A. The problem with having a larger Bermuda Triangle is that it increases the odds of accidents.
B. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to sort through the myth and locate the truth.
C. The increase in ships from East Asia no doubt contributes to an increase in accidents.
D. Most consider the Triangle to stretch from Miami to Puerto Rico and include the island of Bermuda.

Correct answer: C

Rationale: Choice C, 'The increase in ships from East Asia no doubt contributes to an increase in accidents,' represents an opinion statement made by the author. This statement reflects the author's belief or judgment about the impact of increased ships from East Asia on the occurrence of accidents in the Bermuda Triangle. The other choices, A, B, and D, provide factual information or general statements without expressing a personal opinion. Choice A discusses a potential consequence of a larger Bermuda Triangle, choice B highlights the cultural significance and difficulty in discerning truth about the Bermuda Triangle, and choice D describes the commonly accepted geographical boundaries of the Bermuda Triangle. Therefore, choice C is the correct answer as it represents an opinion statement on the part of the author.

3. How did Araminta Ross come to be known as Harriet Tubman?

A. She changed her name to her husband's last name and her first name to her mother's name.
B. She was named after the plantation owner's wife.
C. She changed her name because she was wanted as an Underground Railroad runner.
D. She changed her name to remain anonymous as a Civil War spy.

Correct answer: A

Rationale: Araminta Ross came to be known as Harriet Tubman after marrying a free black man named John Tubman. She took her husband's last name 'Tubman' and changed her first name to 'Harriet,' which was her mother's name. This change of name was a personal choice after her marriage and not because she was named after the plantation owner's wife (B), wanted as an Underground Railroad runner (C), or to remain anonymous as a Civil War spy (D). Therefore, the correct answer is A.

4. Which of the following statements offers a supporting argument for the passage's claim that many coastal islands are eroding?

A. Recent hurricane seasons have been expensive.
B. The Atlantic Basin is entering an active period.
C. Louisiana has lost 2,000 square miles of coastal land.
D. Barrier islands are the first line of defense against coastal storms.

Correct answer: C

Rationale: Statement C directly provides evidence of coastal land erosion by stating that Louisiana has lost a significant amount of coastal land area. This supports the passage's claim that many coastal islands are eroding. Choice A is incorrect because the expense of recent hurricane seasons does not directly relate to coastal land erosion. Choice B is incorrect as the active period of the Atlantic Basin does not specifically address coastal land erosion. Choice D, while related to coastal storms, does not directly support the claim that many coastal islands are eroding.

5. What is the topic excerpt?

A. An interesting birthday party
B. A disappointing buffet menu
C. Dr. Creekstone's eccentricities
D. The lack of adequate lighting at the estate

Correct answer: A

Rationale: The correct answer is A, 'An interesting birthday party.' The passage describes Dr. Oliver Creekstone's remarkable 90th birthday party at his countryside estate, featuring unusual elements like zebras, monster trucks, and a bagpipe player. The guests were surprised by the buffet of boiled asparagus and pickled carrots, and the evening ended with a spectacular fireworks display. Choice B, 'A disappointing buffet menu,' is incorrect as the buffet is just one aspect of the overall event. Choice C, 'Dr. Creekstone's eccentricities,' while partially relevant, does not capture the main focus of the passage. Choice D, 'The lack of adequate lighting at the estate,' is unrelated to the topic of the excerpt.
