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.

Choice A is incorrect because while it might be a common belief among scientists, the politician's agreement is not explicitly mentioned. Choice C is incorrect as it suggests a course of action rather than a point of agreement. Choice D is incorrect as it contradicts the consensus that global temperatures are currently increasing due to human activities, not just natural climate cycles.

4. Raoul has an upcoming school project, and his own computer is not working. He needs to use the library computer, and he has estimated that he will need to be on the computer for approximately an hour and a half. How much of a fee can Raoul expect to pay for his computer use at the library?

A. $6
B. $9
C. $12
D. $15

Correct answer: C

Rationale: Raoul needs to use the computer for 90 minutes. The first 30 minutes are free, so he would pay for the remaining 60 minutes, which is 4 intervals of 15 minutes each. Each 15-minute period incurs a $3 charge, so for 60 minutes, Raoul would pay 4 x $3 = $12. Therefore, Raoul can expect to pay $12 for his computer use at the library. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

5. Which of the following is not a reliable resource for a research paper?

A. The New York Times
B. A personal interview with a politician
C. A medical journal
D. Wikipedia

Correct answer: D

Rationale: Wikipedia is not a reliable source for a research paper due to its open editing format, which may lead to inaccuracies, bias, and lack of authority. While it can be a good starting point for research and general information, it is crucial to verify information from Wikipedia with more academic and reputable sources like peer-reviewed journals, books, or official websites. The New York Times, a personal interview with a politician, and a medical journal are generally considered reliable sources for research papers. The New York Times is a reputable newspaper, personal interviews can provide valuable firsthand insights, and medical journals undergo rigorous peer review processes to ensure accuracy and reliability.
