TEAS 7 English Practice Test

1. Protestors filled the streets of the city because they were dissatisfied with the government’s leadership. Which of the following is an appropriately-punctuated correction for this sentence?

Correct answer: D

Rationale: The correct answer is D. The sentence should be corrected by removing the period and joining the clauses to avoid a sentence fragment. Option A is incorrect because it incorrectly separates the clauses with a comma. Option B is incorrect as it incorrectly uses a comma after 'Protesters' and lacks proper structure. Option C is incorrect as it places the subordinate clause at the beginning, which disrupts the flow of the sentence.

2. What is the primary function of platelets in the blood?

Correct answer: B

Rationale: The correct answer is B: 'To clot blood.' Platelets play a crucial role in the clotting process, forming a plug at the site of blood vessel injury to prevent excessive bleeding. While red blood cells carry oxygen, white blood cells fight infection, and nutrients are transported by plasma, platelets are specifically responsible for blood clotting. Choice A is incorrect because red blood cells are responsible for carrying oxygen. Choice C is incorrect because white blood cells are primarily involved in fighting infection. Choice D is incorrect as the transport of nutrients is mainly carried out by plasma, not platelets.

3. What is the part of speech of the word 'exhaustive' in the sentence: 'Investigators conducted an exhaustive inquiry into the accusations of corruption'?

Correct answer: D

Rationale: The word 'exhaustive' is an adjective in this sentence. Adjectives modify nouns, and in this case, 'exhaustive' is describing the noun 'inquiry.' A noun, verb, or adverb would not be appropriate here. A noun is a person, place, thing, or idea, which 'exhaustive' is not. A verb is an action word, and 'exhaustive' is not functioning as a verb in this sentence. An adverb typically modifies a verb, adjective, or another adverb, but 'exhaustive' is not serving this function in the sentence provided. Therefore, the correct answer is 'D: Adjective.'

4. A spring with a spring constant of 100 N/m is stretched 0.2 m from its equilibrium position. What is the potential energy stored in the spring?

Correct answer: C

Rationale: The potential energy stored in a spring is given by the formula \(PE = \frac{1}{2}kx^2\), where \(k\) is the spring constant and \(x\) is the displacement from the equilibrium position. Substituting the given values, we get \(PE = \frac{1}{2} \times 100 \times (0.2)^2 = 8\) J.

5. What is the energy required to break a chemical bond called?

Correct answer: C

Rationale: Activation energy is the energy required to break a chemical bond and initiate a chemical reaction. It is the minimum amount of energy needed to start a chemical reaction by breaking bonds in the reactant molecules. Kinetic energy (option A) is the energy of motion and is not directly related to breaking chemical bonds. Potential energy (option B) is stored energy that can be converted into other forms of energy but is not specifically about breaking chemical bonds. Bond energy (option D) refers to the energy required to break a particular chemical bond in a molecule and is not the general term for the energy needed to break any chemical bond. Activation energy is crucial in determining the rate of a chemical reaction as it affects the probability of reactant molecules colliding with sufficient energy to surpass the energy barrier and form products.
