1. Choose the meaning of the word inhibiting in the following sentence: 'This medication works by inhibiting the action of a certain enzyme.'

A. Occupying
B. Speeding
C. Hindering
D. Enhancing

Correct answer: C

Rationale: Inhibiting means to prevent, restrain, or impede. In the context of the sentence, inhibiting the action of a certain enzyme refers to hindering or slowing down the enzyme's activity. Choice A ('Occupying') is incorrect as inhibiting does not mean taking up space. Choice B ('Speeding') is incorrect as inhibiting does not mean to accelerate. Choice D ('Enhancing') is incorrect as inhibiting is the opposite of enhancing.

2. What does 'External' refer to?

A. Inside the body
B. Located outside the body
C. Exposed internally
D. Near the skin

Correct answer: B

Rationale: The term 'External' refers to something that is located outside the body. In this context, it specifically denotes a position or location that is beyond the confines of the body's boundaries. Choice A is incorrect as 'External' means outside, not inside. Choice C is incorrect as it confuses the internal exposure with external positioning. Choice D is incorrect as 'External' does not necessarily mean near the skin, but rather outside the body.

3. Which verb correctly completes the sentence? After throwing their sleeping bags into the backseat of their car, they ___ more than 400 miles to reach their destination.

A. Driving
B. Having driven
C. Drove
D. Had drove

Correct answer: C

Rationale: In this sentence, the action of driving more than 400 miles is a past action that already took place after they threw their sleeping bags into the backseat. 'Drove' is the correct past tense form of the verb to match this past action. Choice A, 'Driving,' is in the present participle form and does not correctly indicate the completion of the action in the past. Choice B, 'Having driven,' is in the present perfect form and does not fit the sequence of events in the sentence. Choice D, 'Had drove,' is incorrect due to the incorrect use of 'had' with the past form of 'drive.' Therefore, the most appropriate choice is 'Drove.'

4. What is another word for acrid?

A. Bitter
B. Smoky
C. Nimble
D. Severe

Correct answer: A

Rationale: Acrid is often used to describe a sharp, unpleasant smell or taste, which is synonymous with bitterness. The word 'bitter' closely relates to the strong and sharp sensation associated with acrid qualities. Choice B, 'Smoky,' does not capture the sharpness or unpleasantness associated with acrid, as it refers more to the presence of smoke. Choice C, 'Nimble,' and choice D, 'Severe,' are unrelated to the meaning of acrid and do not serve as synonyms in this context.

5. Which word is NOT USED CORRECTLY in the sentence? They're going to the mall to pick up there uniforms for their coach.

A. Their
B. Going
C. They're
D. There

Correct answer: D

Rationale: The correct answer is D, 'There.' In this context, 'There' is incorrect as it should be replaced with 'their' to show possession, referring to the uniforms belonging to the team. 'Their' (choice A) is used correctly to indicate possession. 'Going' (choice B) and 'They're' (choice C) are also used correctly in the sentence.
