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. During her research, Lise discovers that Freud's theory of the Oedipal complex was based on ancient Greek mythology that was made famous by Sophocles' play Oedipus Rex. To which section of the library should she go if she is interested in reading the play?

A. 300
B. 400
C. 800
D. 900

Correct answer: C

Rationale: The correct answer is C: 800. Greek mythology and literature are typically found in section 800 of the library classification system, which includes works like Oedipus Rex by Sophocles. Choice A (300) pertains to social sciences, choice B (400) covers languages, and choice D (900) focuses on history, geography, and biography, making them incorrect for finding a play like Oedipus Rex.

3. Which of the following statements most accurately summarizes the passage?

A. Tobacco is less healthy than many alternatives.
B. Tobacco is deadly, expensive, and socially unappealing.
C. The US typically taxes tobacco products, leading to high prices.
D. Tobacco products shorten smokers' lives by ten years and kill millions.

Correct answer: B

Rationale: The correct answer is B. The passage extensively details the destructive nature of smoking tobacco products, highlighting the numerous harmful chemicals, addictive properties of nicotine, increased risk of various cancers, serious health conditions, and premature deaths associated with smoking. It also mentions the high costs due to government taxation on tobacco products, alongside the negative social aspects like the smell and staining effects. Choice A is incorrect as the passage emphasizes the severe dangers rather than comparing the healthiness of tobacco to other alternatives. Choice C is incorrect as it focuses solely on the financial aspect of tobacco taxation, omitting the broader health and social consequences discussed in the passage. Choice D is partially correct but not as comprehensive as choice B, which encapsulates the deadly, expensive, and socially unappealing nature of tobacco use as portrayed in the passage.

4. Based on the information provided, what is the most logical reason for this?

A. There are more addresses ending with these numbers than with the other numbers.
B. All residences and businesses have addresses ending in these numbers, and they consume the most water.
C. The residents at these addresses are the most likely to consume more water.
D. The city is more concerned about water usage in the latter part of the week.

Correct answer: D

Rationale: The town of Audley has implemented a water conservation plan with specific watering schedules based on addresses. The city has designated different days for watering based on the ending digits of addresses, suggesting a concern for regulating water usage throughout the week. Choosing option D as the correct answer aligns with the logical reason behind the designated watering schedule. Option A is incorrect as the distribution of addresses ending with specific numbers is not the central reason for the watering schedule. Option B is incorrect as it generalizes that all addresses ending in specific numbers consume the most water, which is not supported by the provided information. Option C is incorrect as it assumes that residents at specific addresses are the most likely to consume more water, which is not explicitly stated in the given extract.

5. Based on the information in the announcement, what might the reader assume about how the university determined the lunch schedule?

A. The university arranged the schedule alphabetically, according to the name of each department.
B. The university checked with the departments in advance to make sure faculty members would be amenable to the change.
C. The university checked to see when the most faculty members from each department would be entering the canteen.
D. The university was more concerned about crowding in the canteen and simply decided to establish different times for each department.

Correct answer: C

Rationale: The announcement states that the university polled the various departments about schedules to determine a recommended roster for each department to visit the canteen for lunch. This indicates that the university checked to see when the most faculty members from each department would be entering the canteen to offset the crowding issue. Therefore, the correct choice is C. Choices A, B, and D are incorrect because there is no mention of arranging the schedule alphabetically, checking with departments in advance for agreement, or simply establishing different times without considering faculty members' schedules in the announcement. The university's approach was to tailor the lunch schedule based on each department's peak entry times to manage the crowding problem effectively.
