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 would this author's attitude likely be towards a person unable to find employment?

A. Descriptive
B. Conciliatory
C. Ingenuous
D. Incredulous

Correct answer: D

Rationale: The author's likely attitude towards a person unable to find employment would be incredulous. The passage emphasizes the abundance of job opportunities in the United States and suggests that finding employment should not be difficult for those willing to work. The author believes that with the numerous avenues of success and available vocations, anyone who is willing to engage in a respectable occupation should be able to find lucrative employment. Therefore, the author would find it hard to believe or be skeptical towards someone who claims they cannot find a job. Choice A, 'Descriptive,' is incorrect as the author's attitude is more judgmental than just describing a situation. Choice B, 'Conciliatory,' is incorrect as the author does not show any intention to reconcile or make peace with the situation of unemployment. Choice C, 'Ingenuous,' is incorrect as this term means innocent or naive, which does not align with the author's likely attitude of disbelief towards unemployment.

3. Which of the following can be logically inferred from the passage?

A. The Vikings disliked exploring the New World.
B. Leif Erikson's banishment led to his exploration of Canada.
C. Leif Erikson never shared his stories with the King of Norway.
D. Historians have difficulty pinpointing events in Viking history.

Correct answer: D

Rationale: The correct answer is D. It can be inferred from the passage that historians have difficulty definitively pinpointing Viking historical events. The passage highlights the uncertainty around Leif Erikson's birth year, conflicting accounts of interactions with natives, and the lack of clarity regarding specific events in Viking history. Choices A, B, and C are incorrect. There is no indication in the passage that the Vikings disliked exploring the New World; Leif Erikson's banishment did not directly lead to his exploration of Canada but rather his desire to spread Christianity and find new lands; and there is no mention of Leif Erikson not sharing his stories with the King of Norway.

4. Which of the following occurred first in Alexander Graham Bell's life?

A. Helped found the National Geographic Society.
B. Developed a metal detector.
C. Moved to Canada.
D. Invented the telephone.

Correct answer: C

Rationale: Alexander Graham Bell moved to Canada early in his life, before inventing the telephone and developing other technologies. Choice A is incorrect because Bell did not help found the National Geographic Society; this happened years after his major inventions. Choice B is incorrect because Bell developed a metal detector after inventing the telephone. Choice D is incorrect because Bell invented the telephone after moving to Canada.

5. Based on the information provided, what is the most logical reason for this?

A. There are more addresses ending with these numbers than with the other numbers.
B. All residences and businesses have addresses ending in these numbers, and they consume the most water.
C. The residents at these addresses are the most likely to consume more water.
D. The city is more concerned about water usage in the latter part of the week.

Correct answer: D

Rationale: The town of Audley has implemented a water conservation plan with specific watering schedules based on addresses. The city has designated different days for watering based on the ending digits of addresses, suggesting a concern for regulating water usage throughout the week. Choosing option D as the correct answer aligns with the logical reason behind the designated watering schedule. Option A is incorrect as the distribution of addresses ending with specific numbers is not the central reason for the watering schedule. Option B is incorrect as it generalizes that all addresses ending in specific numbers consume the most water, which is not supported by the provided information. Option C is incorrect as it assumes that residents at specific addresses are the most likely to consume more water, which is not explicitly stated in the given extract.
