1. What does 'expand' mean?

A. To decrease in size
B. To increase in size or amount
C. To spread out
D. To eliminate

Correct answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

2. A blood vessel that is distended is ____

A. Narrow
B. Swollen
C. Flat
D. Dilated

Correct answer: B

Rationale: The correct answer is B: 'Swollen.' Distended means swollen or expanded, not narrow (A), flat (C), or dilated (D). When a blood vessel is distended, it is enlarged or swollen due to increased pressure.

3. What is another name for the voice box?

A. Trachea
B. Larynx
C. Pharynx
D. Esophagus

Correct answer: B

Rationale: The correct answer is B: Larynx. The voice box is commonly known as the larynx, which plays a vital role in producing sound. The trachea (choice A) is the windpipe that carries air to and from the lungs, not the voice box. The pharynx (choice C) is the throat passageway for air and food, distinct from the voice box. The esophagus (choice D) is the tube that carries food and liquids from the throat to the stomach, not related to the voice box. Therefore, the larynx is the specific anatomical structure referred to as the voice box.

4. What is another word for ABSTAIN?

A. Refrain
B. Indulge
C. Adhere
D. Eliminate

Correct answer: A

Rationale: Refrain is another word for abstain, as both words mean to resist or hold oneself back from doing something. In contrast, indulge (choice B) means to allow oneself to enjoy something freely, making it the opposite of abstain. Adhere (choice C) means to stick to or follow closely, while eliminate (choice D) means to completely remove or get rid of something. Therefore, the correct answer is A, 'Refrain,' which is a synonym for 'abstain.'

5. Select the meaning of the underlined word in the following sentence. Quick action kept the disease from permeating the general population.

A. Conquering
B. Wounding
C. Deterring
D. Infiltrating

Correct answer: D

Rationale: In this context, the word 'permeating' indicates the process of spreading throughout or penetrating into. 'Infiltrating' is the most appropriate synonym for this meaning, as it captures the idea of the disease spreading into the general population. 'Conquering' (Choice A) means to overcome or defeat, which is not the meaning in this context. 'Wounding' (Choice B) means to cause injury, which is not relevant to the sentence. 'Deterring' (Choice C) means to discourage or prevent, which does not fit the context of the disease spreading.
