1. What is the best summary of this passage?

• A. Humans can use coloration and markings on snakes to determine whether they’re venomous.
• B. Animals use coloration to hide from predators.
• C. The scarlet kingsnake and the coral snake have nearly identical markings.
• D. Venomous snakes often have bright markings, although nonvenomous snakes can also mimic those colors.

Correct answer: A

Rationale: The best summary of the passage is that humans can use coloration and markings on snakes to determine whether they're venomous. The passage discusses how snake markings serve the purpose of warning predators and helping humans identify venomous snakes by their bright coloration. Choice B is incorrect because the passage focuses on how coloration helps snakes evade predators rather than hide from them. Choice C is incorrect as it only mentions two specific snakes with similar markings, which is a minor detail compared to the main point of identifying venomous snakes. Choice D is incorrect because it only partially reflects the passage, focusing solely on the relationship between markings and venom in snakes, missing the crucial aspect of human ability to discern venomous snakes based on their coloration.

2. 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.

3. A synonym for disconfirmed would be:

• A. proven
• B. dissipated
• C. distilled
• D. disproven

Correct answer: D

Rationale: The word 'disconfirmed' can be understood by breaking down 'disconfirm,' where 'dis' indicates 'not' and 'confirm' means 'to prove.' Therefore, 'disconfirmed' means 'not proven,' which aligns with the meaning of 'disproven.' In the given passage, it is mentioned that evidence can disprove a hypothesis, not necessarily prove it. This supports the synonymity between 'disconfirmed' and 'disproven.' Choice A ('proven') is incorrect because 'proven' is the opposite of 'disconfirmed.' Choice B ('dissipated') is incorrect as it means to disappear or scatter, not related to disproving a hypothesis. Choice C ('distilled') is incorrect as it means to purify a liquid through heating and cooling, not related to proving or disproving hypotheses.

4. What key idea is conveyed in Frost's poem?

• A. Exploration of love and loss.
• B. Illustration of challenging life decisions.
• C. Reflection on life's journey and choices.
• D. Emphasis on the significance of choosing uncommon paths.

Correct answer: D

Rationale: The correct answer is D. Frost's poem emphasizes that opting for less conventional paths in life adds depth and meaning. Choices A, B, and C are incorrect because the poem specifically focuses on the importance of selecting uncommon routes rather than love, loss, general life decisions, or life's journey.

5. Which of the following statements least supports the argument that the American economy is healthy?

• A. The United States' Gross Domestic Product (GDP) increased by two percent last year.
• B. Unemployment is the lowest it has been in over a decade due to job creation.
• C. Average household income just hit a historical high point.
• D. The output of the United States' manufacturing sector decreased.

Correct answer: D

Rationale: The correct answer is D because a decrease in the manufacturing sector is usually considered a negative indicator for the economy, as it may suggest a decline in production or demand for goods. Choices A, B, and C all provide positive signs for a healthy economy: an increase in GDP reflects economic growth, low unemployment rates indicate a strong job market, and rising household income signifies improved financial well-being for families.
