Reading TEAS Practice Test

1. What is the main idea of the second paragraph?

A. One hairy monkey proves the hypothesis 'All monkeys are hairy.'
B. The same piece of evidence can both confirm and disconfirm a hypothesis.
C. Confirming and disconfirming evidence affect hypotheses differently.
D. The scientific method is not a failsafe method for arriving at objective truth.

Correct answer: C

Rationale: The main idea of the second paragraph is that confirming and disconfirming evidence can affect hypotheses differently, as stated in the passage - 'Single pieces of evidence then, seem to affect a given hypothesis in radically different ways.' Choice A is incorrect because the paragraph discusses how single pieces of evidence affect hypotheses, not that one hairy monkey proves a hypothesis. Choice B is incorrect as the paragraph focuses on the different effects of evidence on hypotheses, rather than its ability to confirm and disconfirm simultaneously. Choice D is incorrect as the paragraph does not primarily discuss the scientific method's failings but rather the impact of evidence on hypotheses.

2. Based on the scenario provided, which of the following inferences can be validly made?

A. This director consistently produces unsuccessful movies.
B. Movie reviews have no impact on the success of a film.
C. The movie reviewers' assessments of the first movie were correct.
D. The director's next movie will receive positive reviews.

Correct answer: C

Rationale: Choice C is the correct answer because the scenario indicates that the negative reviews of the first movie were accurate, as the subsequent poor performance of the movie aligns with the critics' assessments. Choices A and D are incorrect as the scenario only provides information about the first movie and its repercussions, not about the director's consistent performance or the future reception of their movies. Choice B is incorrect because the scenario clearly demonstrates that negative reviews had a significant impact on the movie's performance, contradicting the idea that movie reviews have no influence.

3. How did Hedy Lamarr contribute significantly to the advancement of technology?

A. The technology of the era wasn't advanced enough to easily implement Lamarr's system
B. She collaborated with the science engineering team employed by Howard Hughes, the aviation tycoon
C. She had several failed inventions, such as an improved traffic light and a carbonated drink
D. Her work led to the future development of cellular phones, Bluetooth, and Wi-Fi.

Correct answer: D

Rationale: The correct answer is D because Hedy Lamarr's invention of a frequency-hopping system, along with George Antheil, laid the foundation for technologies like cellular phones, Bluetooth, and Wi-Fi. This significant contribution revolutionized communication technology. Choice A is incorrect because it focuses on the limitations of the era's technology rather than Lamarr's contributions. Choice B is incorrect as it briefly mentions her collaboration but does not directly relate it to technological advancements. Choice C is incorrect as it highlights her failed inventions, which are not indicative of her significant contributions to technology.

4. What does Lady Bracknell's interrogation of Jack reveal about the nature of marriage in the society Wilde is critiquing?

A. It shows that marriage is based on love and personal choice.
B. It reveals that marriage is a serious, thoughtful decision.
C. It illustrates that marriage is more about social standing and wealth than love.
D. It suggests that marriage is an outdated institution.

Correct answer: C

Rationale: Lady Bracknell's interrogation of Jack regarding his suitability as a husband for her daughter Gwendolen reveals that marriage in the society depicted in the play is more about wealth and social status than love. This is evident as Lady Bracknell places great emphasis on Jack's financial background, social connections, and suitability as a match based on these criteria. Choice A is incorrect because Lady Bracknell's focus is not on love or personal choice but on societal expectations and status. Choice B is incorrect as the interrogation highlights superficial considerations rather than portraying marriage as a serious, thoughtful decision. Choice D is also incorrect as the play does not suggest that marriage is outdated, but rather emphasizes its transactional and societal nature in the context of the aristocratic society being critiqued.

5. Why do cicadas make a buzzing sound?

A. To orient via echolocation
B. To attract a mate
C. To locate a food source
D. To ward off predators

Correct answer: B

Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.
