A. Disclosure
B. Pretense
C. Contact
D. Display

Correct answer: C

Rationale: In this sentence, the word 'exposure' is used to refer to coming in contact with the flu virus. Therefore, in this context, the meaning of 'exposure' is related to 'contact.' Choices A, B, and D are incorrect. 'Disclosure' means revealing information, 'pretense' means pretending, and 'display' means to show or exhibit, none of which captures the intended meaning of 'exposure' in the sentence provided.

A. stelic
B. steres
C. sterol
D. sternum

Correct answer: D

Rationale: The breastbone is called the sternum. It is a flat bone located in the center of the chest that connects the ribs together and protects the heart and lungs. The term 'stelic' (choice A), 'steres' (choice B), and 'sterol' (choice C) are not correct terminologies for the breastbone.

3. John Kennedy was a senator before he _____ President in 1960.

A. was elected
B. became
C. was made
D. become

Correct answer: A

Rationale: The correct answer is 'was elected.' This choice is the most appropriate as it correctly indicates the action of being chosen through a voting process in the past. In this context, 'was elected' is the right verb form to show that John Kennedy became President in 1960 after winning an election. The other choices are incorrect: 'became' is a simple past verb form that doesn't convey the electoral process, 'was made' implies a passive action rather than an active election, and 'become' is not the correct past tense form needed in this sentence.

4. Choose the meaning of the word 'affected' in the following sentence: 'Apply a thin film of cream to the affected area once or twice a day depending on the acuteness of the condition.'

A. Involved
B. Diseased
C. Assumed
D. Perceived

Correct answer: B

Rationale: In the context of the sentence, 'affected' is used to describe the area that requires the application of cream. It refers to a part of the body that is diseased or suffering from some ailment. Therefore, the correct meaning of 'affected' in this context is 'Diseased.' Choice A, 'Involved,' does not accurately capture the medical context of the sentence. Choice C, 'Assumed,' is not relevant to the physical condition described in the sentence. Choice D, 'Perceived,' does not convey the idea of a physical ailment, making it incorrect. The most appropriate interpretation is 'Diseased,' as it aligns with the context of applying cream to a specific area due to a health issue.

5. What is another word for CONCAVE?

A. Sunburned
B. Convex
C. Puffed out
D. Sunken

Correct answer: D

Rationale: The correct answer is 'D: Sunken.' Concave refers to a surface or shape that curves inward, while 'sunken' is the closest synonym, also indicating something that is depressed or hollowed inward. Choice 'B: Convex' is incorrect as it is the opposite of concave, representing a shape that bulges outward. Choices 'A: Sunburned' and 'C: Puffed out' do not relate to the concept of concave shapes.
