1. In which sentence is the form 'fast' used as an adverb?

A. The fast car drove over the bridge
B. The car drove fast over the bridge
C. The runner was fast
D. He runs fast

Correct answer: D

Rationale: The sentence 'He runs fast' uses 'fast' correctly as an adverb. An adverb is used to describe a verb and in this case, 'fast' is describing how 'he runs.' Choices A, B, and C use 'fast' as an adjective, not an adverb. In choice A, 'fast' is describing the car, in choice B it is describing how the car drove, and in choice C it is describing the runner.

2. This medication works by inhibiting the action of a certain enzyme. What does inhibiting mean?

A. Blocking
B. Hindering
C. Energizing
D. Blocking improvement

Correct answer: B

Rationale: The correct answer is 'B: Hindering.' Inhibiting means to hinder or slow down a process. Choices A and D are similar and imply a complete stop of the process rather than just slowing it down. Choice C, 'Energizing,' is the opposite of inhibiting, as it means to provide energy or stimulate rather than hinder.

3. What is another word for panacea?

A. Poison
B. Cure
C. Treatment
D. Remedy

Correct answer: B

Rationale: The correct answer is B: Cure. A panacea is a remedy or cure for all diseases. While 'poison' (choice A) is the opposite of a cure, 'treatment' (choice C) is a general approach to addressing an illness rather than a universal solution, and 'remedy' (choice D) is synonymous with cure but not as closely related to the concept of a universal remedy as 'cure'.

4. What does Endogenous mean?

A. Produced outside the body
B. Produced within the body
C. Taken from an external source
D. Linked to environmental factors

Correct answer: B

Rationale: The correct answer is B: 'Produced within the body.' Endogenous refers to substances or processes that originate or are produced within an organism or system. Choices A, C, and D are incorrect. Choice A, 'Produced outside the body,' is the opposite of endogenous. Choice C, 'Taken from an external source,' describes exogenous rather than endogenous. Choice D, 'Linked to environmental factors,' is not a direct definition of endogenous.

5. What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?

A. Fallback
B. Substitute
C. Control
D. Curative

Correct answer: C

Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.
