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 word 'principal' refer to in the following text?

A. Primary or chief
B. An acolyte
C. An individual who provides nurturing
D. One in a subordinate position

Correct answer: A

Rationale: In this context, the word 'principal' refers to the primary or chief role that Reldresal holds as the principal secretary for private affairs. This term signifies his significant position and authority within the hierarchy. The other choices are incorrect because 'principal' does not mean 'an acolyte' (a follower or assistant), 'an individual who provides nurturing,' or 'one in a subordinate position.'

3. Based on the passage, which conclusion can be drawn about the author?

A. They are overly emotional and...
B. They would rather be at a concert
C. They go to the theater as often as possible
D. They enjoy the decor of most theaters

Correct answer: C

Rationale: The correct answer is C. The passage does not mention anything about the author's emotional state or preference for concerts. However, it does discuss cicadas and their emergence, life cycle, and behavior. Therefore, the reader can conclude that the author is likely interested in cicadas and their natural history, indicating that they go to the theater as often as possible. Choice A is incorrect because there is no evidence regarding the author being overly emotional. Choice B is incorrect as there is no mention of the author's preference for concerts. Choice D is incorrect as the passage does not provide any information about the author enjoying theater decor.

4. Which source provides the best material for your assignment?

A. It may be true that some businesses profit from buying up wetlands; however, the important point is that wetlands are disappearing. An ecologist noted that there are not enough private donors to buy these places.
B. Greedy businesses are at the heart of the problem: they simply want to buy up cheap land to build and make money. They don't care about destroying our natural treasures. The physics professor noted that our town needs to buy this land.
C. It's clear that wetlands are endangered; they are going to disappear unless we do something about it. We should get private donors to buy the land. An ecologist noted that wetlands are in danger.
D. Businesses are part of the wetland problem. Without developers to buy them up, the town would not need to purchase the land to protect it. A physics professor noted that the wetland problem is related to greed.

Correct answer: C

Rationale: Source C provides the best material for the assignment because it emphasizes the importance of preserving wetlands, acknowledges the endangered status of wetlands, and suggests a solution involving private donors. The source highlights the crucial issue at hand - the disappearance of wetlands - and proposes a practical solution, making it a reliable and relevant source for an assignment on wetlands conservation. Choice A focuses more on the profit aspect rather than conservation. Choice B blames greedy businesses without offering a practical solution. Choice D discusses the relationship between businesses and wetlands but lacks a clear solution for conservation compared to Source C.

5. Which of the following best provides detailed support for the claim that 'seatbelts save lives'?

A. A government website containing driving accident information
B. A blog developed by one of the largest car companies in the world
C. An encyclopedia entry on the seatbelt and its development
D. A social media post from a famous race car driver

Correct answer: A

Rationale: The correct answer is A. Government websites usually contain reliable and detailed statistics supporting the effectiveness of seatbelts. Choice B, a blog from a car company, may have biased information to promote their products. Choice C, an encyclopedia entry, may not necessarily have the most up-to-date or detailed information on the topic. Choice D, a social media post from a race car driver, lacks the credibility and detailed information that a government website can provide.
