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. Which definition most closely relates to the usage of the word 'moult' in the passage?

A. An adventure of sorts, especially underwater
B. Mating act between two insects
C. The act of shedding part or all of the outer shell
D. Death of an organism that ends in a revival of life

Correct answer: C

Rationale: 'Moult' refers to the act of shedding the outer shell, which is part of the insect's development. In the passage, it mentions insects that remain continually under water until they are ready to undergo their final moult and attain the winged state. This process of shedding the outer shell is crucial for insects transitioning from their aquatic larval stage to their aerial adult stage. Choices A, B, and D do not align with the specific context provided in the passage about the term 'moult.'

3. What is the definition of the word haunt in the following passage?

A. To levitate
B. To constantly visit
C. To terrorize
D. To daunt

Correct answer: B

Rationale: In this context, 'haunt' means to constantly visit a place. Mr. Utterson is repeatedly going over the details of the situation in his mind, engaging with the problem persistently, as seen in the passage. The word does not imply levitation, terrorizing, or daunting in this context, making choices A, C, and D incorrect.

4. Which of the following represents an opinion statement on the part of the author?

A. The problem with having a larger Bermuda Triangle is that it increases the odds of accidents.
B. The area known as the Bermuda Triangle has become such a part of popular culture that it can be difficult to sort through the myth and locate the truth.
C. The increase in ships from East Asia no doubt contributes to an increase in accidents.
D. Most consider the Triangle to stretch from Miami to Puerto Rico and include the island of Bermuda.

Correct answer: C

Rationale: Choice C, 'The increase in ships from East Asia no doubt contributes to an increase in accidents,' represents an opinion statement made by the author. This statement reflects the author's belief or judgment about the impact of increased ships from East Asia on the occurrence of accidents in the Bermuda Triangle. The other choices, A, B, and D, provide factual information or general statements without expressing a personal opinion. Choice A discusses a potential consequence of a larger Bermuda Triangle, choice B highlights the cultural significance and difficulty in discerning truth about the Bermuda Triangle, and choice D describes the commonly accepted geographical boundaries of the Bermuda Triangle. Therefore, choice C is the correct answer as it represents an opinion statement on the part of the author.

5. When should you redirect your dog's biting behavior?

A. When your dog bites something inappropriate
B. When your dog barks at strangers
C. When your dog is lying down
D. When your dog is eating

Correct answer: A

Rationale: You should redirect your dog's biting behavior when it bites something inappropriate. This can include redirecting its attention to an appropriate chew toy and using biting deterrent spray. The extract suggests that redirecting biting behavior is necessary when your dog bites something it shouldn't.
