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. Considering the list of works that Angela read, into which category does 'The Cask of Amontillado' most likely fit?

A. newspaper article
B. book chapter
C. short story
D. television show episode

Correct answer: C

Rationale: 'The Cask of Amontillado' by Edgar Allan Poe is most likely a short story based on the information provided. The list of works that Angela read consisted of classic literature. Since the rule states that short stories should be placed in quotation marks, it aligns with the formatting rule. Therefore, 'The Cask of Amontillado' is most likely categorized as a short story. Choice A, newspaper article, is incorrect because newspaper articles are usually not considered classic literature. Choice B, book chapter, is incorrect as 'The Cask of Amontillado' is a standalone work and not a chapter within a book. Choice D, television show episode, is incorrect as the list of works provided consists of classic literary works, not television shows.

3. What is the best definition of the underlined word in the selection below, taken from the third paragraph of the passage? 'You should try to be aware of your consumption of water and energy.'

A. Using the greatest amount
B. Illness of the lungs
C. Using the least amount
D. Depletion of goods

Correct answer: D

Rationale: In this context, 'consumption' refers to the use or depletion of resources like water and energy. It is not about using the greatest amount (choice A) or the least amount (choice C) but about being mindful of how much you use to avoid depletion. 'Illness of the lungs' (choice B) is completely unrelated to the context of resource conservation discussed in the passage.

4. 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.

5. What is the author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air?

A. To emphasize the adaptability and complexity of insect life cycles.
B. To compare aquatic insects with those that remain airborne.
C. To highlight the unique features of insects that live in both environments.
D. To question the validity of studying insects that live in only one environment.

Correct answer: A

Rationale: The author's purpose in discussing aquatic insects in relation to those that spend their entire lives in the air is to emphasize the adaptability and complexity of insect life cycles. The author highlights how some insects transition between aquatic and aerial environments, showcasing the diverse strategies and features these insects possess to thrive in different habitats. Choice B is incorrect because the author is not solely comparing aquatic insects with those that remain airborne, but rather exploring their adaptability. Choice C is incorrect as the focus is not on highlighting unique features but on showcasing the transition between environments. Choice D is incorrect as the author is not questioning the validity of studying insects in only one environment but rather demonstrating the fascinating dual-life cycles of certain insects.
