1. What word best describes the organization of this passage?

• A. Modeling
• B. Hypothesizing
• C. Explaining
• D. Observing

Correct answer: C

Rationale: The correct answer is 'Explaining.' The passage is structured in an explanatory manner, providing a detailed account of how a plunger works. It explains the process step by step, from the initial depression of the plunger to the increase in pressure inside the clogged pipe. 'Modeling' and 'Observing' are not suitable choices as the passage does not involve creating models or direct observations. 'Hypothesizing' is also incorrect as the passage focuses on describing the functioning of a plunger rather than proposing or discussing potential hypotheses.

2. According to the food chain diagram, which of the following animals has no natural predators?

• A. Vulture
• B. Cobra
• C. Mongoose
• D. Aardvark

Correct answer: B

Rationale: The correct answer is B, Cobra. In the food chain diagram, cobras are often considered apex predators, meaning they are at the top of the food chain and do not have natural predators. Vultures (choice A), although scavengers, may face competition but not direct predators. Mongooses (choice C) are known for preying on snakes, including cobras, and aardvarks (choice D) are part of the food chain and have predators like lions and hyenas.

3. What is implied by the following sentence? It is hoped the wounds may not be mortal. My apprehension is that they will prove fatal.

• A. Those involved are hopeful for a positive outcome.
• B. There is no hope that Seward or Lincoln will recover from their wounds.
• C. The writer is pessimistic about whether Seward will recover from his wounds.
• D. The writer is doubtful about the legitimacy of accounts regarding the night's events.

Correct answer: C

Rationale: The sentence 'My apprehension is that they will prove fatal' indicates that the writer is pessimistic about Seward's recovery from his wounds. This implies a lack of hope or certainty about the outcome, suggesting a negative view on the situation. Choice A is incorrect because the sentence does not refer to all involved parties being hopeful. Choice B is incorrect as it is too extreme, stating there is no hope for recovery. Choice D is incorrect as there is no indication in the sentence that the writer doubts the legitimacy of the accounts.

4. 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.

5. First-hand accounts of an event, subject matter, time period, or an individual are referred to as what type of source?

• A. Primary sources
• B. Secondary sources
• C. Direct sources
• D. Indirect sources

Correct answer: A

Rationale: First-hand accounts, like the speech by Charles Dickens, are considered primary sources as they provide direct evidence or original data from the event or time period. Primary sources offer firsthand information, such as diaries, speeches, letters, autobiographies, or original research reports. Secondary sources interpret and analyze primary sources, making them one step removed from the original event or period. Direct and indirect sources are not commonly used terms in the context of primary and secondary sources.
