- B. Difficult to arouse
- C. Energized
- D. Wide awake
Correct answer: B
Rationale: Lethargic refers to a state of sluggishness or drowsiness, making it difficult for a person to become alert or aroused. This term is the opposite of being active, energized, or wide awake. Choice A is incorrect as 'lethargic' is the opposite of 'active.' Choice C is incorrect as 'lethargic' implies a lack of energy. Choice D is incorrect as 'lethargic' signifies drowsiness, the opposite of being 'wide awake.' The correct answer is B.
2. What is the best description for the abbreviation CDC?
- A. An online social network
- B. A test for postgraduate students
- C. A well-known pharmaceutical
- D. A public health association
Correct answer: D
Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.
3. 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.

- D. Conclusion
Correct answer: A
Rationale: In the context of the sentence provided, efficacy refers to the ability of counterfeit medicines to produce the intended or desired effect. Efficacy is closely related to effectiveness, which is the correct description in this context.

- D. The list included, flu, etc., measles, diseases, and other items.
Correct answer: A
Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.
