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 sources would be a good starting point that provides the most accurate information for a research project on ancient Persian culture?

• A. The Wikipedia entry on 'Persian Culture'
• B. 'All Cool Persian Stuff,' a blog written by a scientist
• C. 'An Overview of Persian Society,' a book written by a historian
• D. 'Uncovering the Secrets of Persia,' a two-page magazine article about lost temples

Correct answer: C

Rationale: A book written by a historian, such as 'An Overview of Persian Society,' would provide a well-researched and reliable source of information on ancient Persian culture. Choice A, the Wikipedia entry, may contain inaccurate or biased information as it can be edited by anyone. Choice B, a blog by a scientist, may not provide scholarly or comprehensive information on ancient Persian culture. Choice D, a magazine article about lost temples, does not focus on Persian culture as a whole, making it less relevant for a research project specifically on ancient Persian culture.

3. What does the word 'wise' in this passage most closely mean?

• A. Manner
• B. Knowledge
• C. Shrewd
• D. Ignorance

Correct answer: A

Rationale: In the context of the passage, the word 'wise' refers to the 'manner' in which the sun-fish builds its hatchery. It describes the careful and skillful way in which the mother sun-fish constructs and provides for her offspring. Choice B, 'Knowledge,' is incorrect as the word 'wise' does not specifically imply knowledge in this passage. Choice C, 'Shrewd,' is incorrect as it suggests cleverness or astuteness, which is not the intended meaning here. Choice D, 'Ignorance,' is the opposite of 'wise' and does not align with the context of the passage.

4. What source would be most useful in determining the reliability of Punxsutawney Phil's predictions over a number of years?

• A. A memoir from a former president of the Groundhog Club
• B. A record of weather patterns over the past decade
• C. An article on groundhog behavior in the northeast U.S
• D. A historical account of Groundhog Day traditions

Correct answer: B

Rationale: A record of weather patterns over the past decade would be the most useful source in determining the reliability of Punxsutawney Phil's predictions. By comparing Phil's forecasts with the actual weather outcomes, one can analyze the accuracy of his predictions. Choices A, C, and D do not directly provide the necessary data on weather patterns to evaluate Phil's reliability.

5. What best describes Samuel's sample size?

• A. The sample is biased because it has firsthand experience.
• B. The sample contains too few members to draw meaningful conclusions.
• C. The sample contains too many members to make specific claims.
• D. The sample is unbiased and of appropriate size.

Correct answer: B

Rationale: Samuel's sample size of 24 students is too small to draw generalizable conclusions about a larger population. While his observations are based on firsthand experience, the sample size is inadequate to make meaningful claims about the relationship between parental involvement and academic success for all students. Choice A is incorrect because bias is not related to sample size but rather the way data is collected. Choice C is incorrect as having too many members would not hinder understanding specifics, but rather provide a more comprehensive view. Choice D is incorrect as the sample size is too small to be considered appropriately sized for making broad claims.
