Practice TEAS Test Reading

1. Which of the following is true of hypotheses of the form 'All x are y'?

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. What is the primary purpose of the passage?

Correct answer: D

Rationale: The primary purpose of the passage is to suggest that viewers think critically about the underlying assumptions in the movies they watch. It discusses how American war movies often conform to a Western paradigm and urges readers to analyze these portrayals and question the messages being conveyed. Choice A is incorrect because the passage does not focus on analyzing an interesting feature of American cinema but rather on prompting critical thinking. Choice B is incorrect as the passage does not aim to refute the Western paradigm but rather to highlight its influence on American war movies. Choice C is incorrect as the passage does not suggest a way to improve war movies but rather encourages viewers to be more mindful and aware of the underlying assumptions in the movies they consume.

3. In the context of the article, the word mortal means

Correct answer: C

Rationale: In the context of the article describing the assassination of President Lincoln, the word 'mortal' is used to describe a wound that will cause death. The sentence 'The wound is mortal' indicates that the wound is fatal and will result in the President's death. Therefore, the correct synonym for 'mortal' in this context is 'fatal,' meaning causing death. Choice A, 'deadly,' is the best synonym as it directly relates to causing death. Choices B and D, 'recoverable' and 'dangerous,' do not accurately reflect the meaning of 'mortal' in this context.

4. When evaluating the credibility of research sources, which of the following is a valid consideration?

Correct answer: A

Rationale: The correct answer is A. It is credible if published in a peer-reviewed scholarly journal because peer review ensures that the research has been evaluated by experts in the field for quality and accuracy before publication. This process enhances the credibility of the research source. Choice B is incorrect because not all online sources are unreliable; credibility depends on various factors beyond the publication medium. Choice C is incorrect because author affiliations can indeed impact credibility, but they are not the sole determinant. Choice D is incorrect as the frequency of citations can indicate the impact of a source but does not guarantee its credibility.

5. In a volleyball game, who can score a point?

Correct answer: B

Rationale: According to the passage, only the serving team can score in a volleyball game. After the ball is served, the serving team earns points by winning a rally. The receiving team aims to stop the serving team and win the rally to gain the serve. Therefore, the correct answer is the serving team. Choices A, C, and D are incorrect as the receiving team does not score points, both teams do not score, and there is indeed scoring in volleyball.
