Reading TEAS Practice Test

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. What does the author imply will happen if people do not follow his suggestions?

A. The author implies we will run out of resources in the next 10 years.
B. The author implies water and energy prices will rise sharply in the near future.
C. The author implies global warming and the depletion of natural resources will continue.
D. The author implies local farmers will lose their farms.

Correct answer: C

Rationale: The author implies that neglecting the recommended actions will lead to the continued degradation of the environment and depletion of resources. The passage emphasizes the importance of being proactive in conserving resources to combat global warming and the depletion of natural resources. Choice A is incorrect because the author doesn't specify a timeframe for running out of resources. Choice B is incorrect as the focus is on environmental impact rather than economic consequences. Choice D is incorrect as the passage does not specifically mention the impact on local farmers.

3. Which of the following words does the author use to express a derogatory tone?

A. Predictable
B. Noisy
C. Delicate
D. Roar

Correct answer: A

Rationale: The correct answer is 'Predictable' because the author uses it in a negative context to imply something as uninspired or lacking creativity. In the passage, the author mentions that following rules can make writing difficult, contrasting writers who adhere to rules with those who break them to succeed. 'Predictable' reflects a derogatory tone as it suggests monotony or lack of originality. Choices B, C, and D do not convey a derogatory tone in the context of the passage. 'Noisy,' 'Delicate,' and 'Roar' are neutral or descriptive words that do not carry a negative connotation.

4. Which of the following can be logically inferred from the passage?

A. The Vikings disliked exploring the New World.
B. Leif Erikson's banishment led to his exploration of Canada.
C. Leif Erikson never shared his stories with the King of Norway.
D. Historians have difficulty pinpointing events in Viking history.

Correct answer: D

Rationale: The correct answer is D. It can be inferred from the passage that historians have difficulty definitively pinpointing Viking historical events. The passage highlights the uncertainty around Leif Erikson's birth year, conflicting accounts of interactions with natives, and the lack of clarity regarding specific events in Viking history. Choices A, B, and C are incorrect. There is no indication in the passage that the Vikings disliked exploring the New World; Leif Erikson's banishment did not directly lead to his exploration of Canada but rather his desire to spread Christianity and find new lands; and there is no mention of Leif Erikson not sharing his stories with the King of Norway.

5. What is the best definition of economy as it is used in this passage?

A. Exchange of money, goods, and services
B. Delegation of household affairs
C. Efficient money management
D. Less expensive

Correct answer: C

Rationale: The correct definition of 'economy' in this passage is 'efficient money management.' The passage emphasizes the importance of expending less than what is earned, which is a key aspect of efficient money management. Choice A, 'Exchange of money, goods, and services,' is too broad and does not capture the essence of the passage. Choice B, 'Delegation of household affairs,' is not directly related to the context of the passage. Choice D, 'Less expensive,' does not encompass the concept of managing money efficiently as discussed in the passage.
