1. Which of the following is true of hypotheses of the form 'All x and 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: C

Rationale: The correct answer is C. According to the passage, when encountering evidence that disproves a hypothesis of the form 'All x and y,' something that is x but not y can disprove the hypothesis. Using the example provided in the passage, a monkey (x) that has no hair (not y) would disprove the hypothesis 'All monkeys are hairy.' Choice A is incorrect because something that is neither x nor y is not specifically mentioned in the passage to disprove such hypotheses. Choice B is incorrect because the passage states that something that is both x and y confirms the hypothesis, not disproves it. Choice D is incorrect as the passage does not discuss something that is y but not x disproving the hypothesis; it focuses on x but not y as evidence to disprove the hypothesis.

2. A 'competitive salary' is one that is

A. Much less than salaries offered for comparable jobs
B. Much greater than salaries offered for comparable jobs
C. Similar to the average salary offered for comparable jobs
D. Impossible to compare to the salaries offered for comparable jobs

Correct answer: C

Rationale: A competitive salary is one that is similar to the average salary offered for comparable jobs. In the context of the job advertisement provided, a competitive salary is typically in line with what other employers are paying for similar positions to attract and retain the best talent in the industry. Choice A is incorrect because a competitive salary is not 'much less' than salaries offered for comparable jobs; it aims to be competitive. Choice B is incorrect as a competitive salary is not 'much greater' than salaries offered for comparable jobs; it aims to be fair and competitive. Choice D is incorrect as a competitive salary is not 'impossible to compare to' the salaries offered for comparable jobs; it is meant to be competitive and aligned with industry standards.

3. Which of the following battles occurred first?

A. Cold Harbor
B. Chancellorsville
C. Atlanta
D. Shiloh

Correct answer: D

Rationale: Shiloh occurred earlier than the other battles listed. Shiloh took place in April 1862 during the American Civil War, making it the earliest battle among the options provided. Cold Harbor occurred in June 1864, Chancellorsville in May 1863, and Atlanta in July-September 1864. Therefore, Shiloh is the correct answer. Choice A (Cold Harbor) is incorrect because it happened after Shiloh. Choice B (Chancellorsville) is incorrect because it occurred after Shiloh. Choice C (Atlanta) is also incorrect as it took place after Shiloh.

4. Which of the following labels best describes the previous passage?

A. comparison essay
B. definition essay
C. cause and effect essay
D. persuasive essay

Correct answer: C

Rationale: The passage delves into the relationship between magnesium intake and health outcomes, highlighting how deficiencies in magnesium can lead to various health issues. It discusses how different factors, such as gastrointestinal disorders or dietary habits, can cause magnesium depletion and its subsequent effects on the body. This focus on exploring the cause-and-effect connections between magnesium levels and health conditions aligns with the characteristics of a cause and effect essay, making choice C the most appropriate. Choices A, B, and D are incorrect because the passage does not focus on comparing different concepts, providing definitions, or persuading the reader of a particular viewpoint.

5. What is the main argument presented in the passage?

A. The custom of tipping should be abolished in favor of paying servers a living wage
B. Tipping enhances service quality in restaurants
C. Servers' pay should be determined by their performance
D. Customers derive pleasure from the custom of tipping

Correct answer: A

Rationale: The correct answer is A: 'The custom of tipping should be abolished in favor of paying servers a living wage.' The rationale is that the passage argues for eliminating tipping and ensuring servers receive a fair wage. This is supported by the idea that servers should be paid adequately rather than relying on tips. Choice B is incorrect because the passage does not support the idea that tipping enhances service quality; it argues for a living wage instead. Choice C is incorrect as there is no mention of paying servers based on performance in the passage. Choice D is incorrect as the passage does not focus on customers' enjoyment of tipping but rather on the need to abolish the practice for fairer wages.
