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. In which of the following battles were there more Confederate casualties than Union casualties?

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

Correct answer: D

Rationale: Shiloh had more Confederate casualties than Union casualties. In the Battle of Shiloh, fought in April 1862, the Confederates suffered around 10,700 casualties, while the Union forces had approximately 13,000 casualties. Therefore, Shiloh is the correct answer. Choice A, Cold Harbor, is incorrect because in that battle, the Confederate casualties were fewer than the Union casualties. Choices B and C, Chancellorsville and Atlanta respectively, also had more Union casualties than Confederate casualties, making them incorrect answers.

3. Which of the following best describes the organization of the information in the passage?

A. cause-effect
B. chronological sequence
C. problem-solution
D. comparison-contrast

Correct answer: B

Rationale: The passage is organized in a chronological sequence, starting from the reign of King Charles II, proceeding to his death without a legitimate heir, the ascension of his brother James II, and the events that followed with the birth of James II's son and the subsequent fleeing of the family. The passage then covers the rejection of the young James as heir, the rise of the Jacobites, and the defeat at the Battle of Culloden in 1746. Each event is presented in the order in which they occurred. The other answer choices are incorrect: cause-effect implies a relationship of events leading to each other, problem-solution focuses on identifying issues and resolving them, and comparison-contrast involves highlighting similarities and differences between subjects, none of which are the primary organizational structure of the passage.

4. At the top of an encyclopedia's page are the following two guide terms: kingcraft and klieg light. Which one of the following words will be found on this page?

A. Kleptomania
B. Knead
C. Kinesthesia
D. Kickback

Correct answer: C

Rationale: The correct answer is C, 'Kinesthesia.' When arranging words alphabetically, 'Kinesthesia' would come between 'kingcraft' and 'klieg light.' Choice A, 'Kleptomania,' starts with a 'K' but comes after 'Kinesthesia.' Choices B and D, 'Knead' and 'Kickback,' do not fit alphabetically between the guide terms provided at the top of the page.

5. What is the new word?

A. REVEST
B. REVERT
C. REVIEW
D. REVERSE

Correct answer: B

Rationale: The new word can be formed by following the transformation steps: Remove the P, Replace the first A with the final E, Remove the I, Remove the C, and Remove the A from PREVARICATE, resulting in the word 'REVERT.' Choices A, C, and D do not match the rearrangement of letters provided in the instructions.
