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 of the following sentences correctly uses a hyphen?

A. Last year, many of the players felt unsure of the coach's methods.
B. Some of the furniture she selected seemed a bit over-the-top for the space.
C. Henry is a beagle-mix and is ready for adoption this weekend.
D. Geena works to maintain a good relationship with her ex-husband to the benefit of their children.

Correct answer: C

Rationale: The correct usage of a hyphen is seen in sentence C, 'Henry is a beagle-mix and is ready for adoption this weekend.' The hyphen is used in 'beagle-mix' to link the two words together to describe Henry's breed accurately. Choice A contains a comma incorrectly placed after 'Last year.' Choice B uses hyphens as dashes, which is incorrect. Choice D does not require a hyphen as there is no compound term or adjective that needs to be linked.

3. Which of the following is NOT a property of a catalyst?

A. Increases the rate of a reaction
B. Remains unchanged after the reaction
C. Lowers the activation energy
D. Creates new products

Correct answer: D

Rationale: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. It remains unchanged after the reaction, which eliminates option B. A catalyst works by lowering the activation energy required for the reaction to occur, which eliminates option C. A catalyst does not create new products in a reaction; it only facilitates the conversion of reactants into products more efficiently. Therefore, option D is NOT a property of a catalyst.

4. The speaker's enthusiasm was contagious. Which word is the noun form of the adjective 'enthusiastic'?

A. enthusiastic
B. enthusiastically
C. enthusiasm
D. enthuse

Correct answer: C

Rationale: The correct answer is 'C: enthusiasm.' The noun form of the adjective 'enthusiastic' is 'enthusiasm.' Nouns are often formed from adjectives by changing the suffix; in this case, '-ic' in 'enthusiastic' changes to '-m' in 'enthusiasm.' 'Entusiastic' is an adjective and does not function as a noun. 'Enthusiastically' is an adverb as it describes how something is done, not a noun. 'Enthuse' is a verb and does not represent the noun form of 'enthusiastic.' It is important to understand the relationships between different parts of speech when analyzing word forms.

5. What is the rigid structure that provides shape and support to plant cells?

A. Cell wall
B. Plasma membrane
C. Nucleus
D. Cytoplasm

Correct answer: A

Rationale: The correct answer is the cell wall, as it is the rigid structure that provides shape and support to plant cells. The cell wall is located outside the plasma membrane and is primarily composed of cellulose, giving it its rigid nature. The plasma membrane (option B) is a semi-permeable membrane surrounding the cell that regulates the movement of substances in and out of the cell. The nucleus (option C) houses the cell's genetic material and controls cellular activities. Cytoplasm (option D) is the gel-like substance within the cell that surrounds organelles and where various cellular processes take place, but it does not provide the rigid structure and support that the cell wall does.
