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 is the meaning of testament as used in the sentence provided?

A. story
B. surprise
C. artifact
D. evidence

Correct answer: D

Rationale: In the context provided, the word 'testament' most likely refers to evidence. A testament can be something that serves as proof or confirmation of a fact or situation. In this case, it is used in a non-religious sense to indicate evidence or proof. The other choices are incorrect as 'story' does not fit the context, 'surprise' is not related to the owners' skills mentioned, and 'artifact' does not align with the discussion of the restaurant's success.

3. What was the author's purpose in writing this passage about George Washington?

A. To inform readers about Washington's advice and its relevance to modern times.
B. To introduce George Washington as a historical figure.
C. To emphasize that George Washington had a multifaceted role beyond being a military hero.
D. To persuade readers that George Washington is a hero of liberty.

Correct answer: A

Rationale: The correct answer is A: 'To inform readers about Washington's advice and its relevance to modern times.' The passage focuses on Washington's advice, leadership, and legacy, particularly his farewell address, highlighting its significance in current times. This choice accurately reflects the primary purpose of the passage. Choice B is incorrect because the passage goes beyond mere introduction, delving into Washington's actions and beliefs. Choice C is incorrect as while the passage does mention Washington's multifaceted role, the primary focus is on his advice and legacy. Choice D is incorrect because the passage does not aim to persuade readers of Washington's heroism but rather inform them about his advice and principles.

4. Which of the following would weaken the author's argument?

A. a report revealing that the cited study was funded by a company that provides discounted tutoring through schools
B. a study demonstrating differences in standardized test scores among students at schools in various neighborhoods
C. a statement signed by local teachers affirming that they do not give preferential treatment in the classroom or during grading
D. a study indicating that GPA has a weak correlation with success in college

Correct answer: A

Rationale: Choice A weakens the author's argument by highlighting a potential conflict of interest. If the cited study was funded by a company offering discounted tutoring, it could introduce bias and question the credibility of the study's findings. This revelation could cast doubt on the objectivity and reliability of the research, ultimately undermining the argument based on the cited study. Choices B, C, and D do not directly impact the credibility or objectivity of the cited study, so they would not significantly weaken the author's argument.

5. What source would be most useful in determining the reliability of Punxsutawney Phil's predictions over a number of years?

A. A memoir from a former president of the Groundhog Club
B. A record of weather patterns over the past decade
C. An article on groundhog behavior in the northeast U.S
D. A historical account of Groundhog Day traditions

Correct answer: B

Rationale: A record of weather patterns over the past decade would be the most useful source in determining the reliability of Punxsutawney Phil's predictions. By comparing Phil's forecasts with the actual weather outcomes, one can analyze the accuracy of his predictions. Choices A, C, and D do not directly provide the necessary data on weather patterns to evaluate Phil's reliability.
