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. 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.

3. Sarah is hosting a brunch for a baby shower and knows that several of the guests are strict vegans. She wants to make sure she prepares certain foods correctly to ensure all her guests have something to eat. In particular, she is looking for recipes for banana bread and blueberry muffins. Which chapter of the cookbook should she consult?

A. Chapter I
B. Chapter II
C. Chapter IV
D. Chapter V

Correct answer: B

Rationale: Chapter II typically focuses on baking and sweet treats, which would likely include recipes for banana bread and blueberry muffins. Sarah should consult this chapter for vegan-friendly versions of these recipes that will cater to her strict vegan guests. Choice A, Chapter I, primarily covers yeast breads, not the specific recipes Sarah is looking for. Choice C, Chapter IV, focuses on elegant, easy entrees, which are not relevant to the sweet treats Sarah wants. Choice D, Chapter V, covers delicious desserts and drinks, but it does not specifically mention the items Sarah is interested in, making it less likely to contain the recipes she needs.

4. Which aspect of writing engages and connects with the audience, igniting emotion?

A. Ethos
B. Logos
C. Pathos
D. Kairos

Correct answer: C

Rationale: The correct answer is C, 'Pathos.' Pathos refers to the emotional appeal in writing that aims to engage and connect with the audience's emotions. In the provided extract, Charles Dickens appeals to the emotions of the working men and their families, expressing his earnest hope for their involvement in the Mechanic's Institution. Ethos (choice A) relates to ethical appeal, establishing credibility. Logos (choice B) refers to logical appeal, using reason and evidence. Kairos (choice D) pertains to the timeliness or relevance of an argument, considering the opportune moment for persuasion. In this context, Dickens employs pathos to emotionally connect with the audience and convey his message effectively.

5. In which chapter should she look for more information on herbal remedies to combat eczema?

A. Chapter 8
B. Chapter 10
C. Chapter 11
D. Chapter 12

Correct answer: D

Rationale: Eczema is a topical condition, so Chapter 12 (section D) would be the most appropriate place to look for information on herbal remedies to combat it. Chapter 8 focuses on herbs for adult needs, and while it may contain some relevant information, it is not specific to topical conditions like eczema. Chapters 10 and 11 cover respiratory and digestive conditions respectively, which are not relevant to treating eczema. Therefore, Chapter 12 is the best choice for Clothilde to find herbal remedies to combat eczema.
