A. Makes a suggestion about
B. Gives evidence about
C. Hints at the idea that
D. Promotes a plan to

Correct answer: A

Rationale: The correct answer is A: 'Makes a suggestion about.' The phrase 'suggests that' indicates that the study is proposing or indicating the possibility that vaping may have certain effects on cigarette smoking. It is not stating a fact or providing evidence, but rather making a suggestion or recommendation about the relationship between vaping and cigarette smoking. Choices B, C, and D are incorrect because the phrase 'suggests that' does not provide evidence, hint at an idea, or promote a plan, but rather presents a suggestion or possibility.

A. Inferior
B. Transverse
C. Dorsal
D. Ventral

Correct answer: D

Rationale: The correct answer is 'Ventral' because it specifically refers to the lower surface of a structure. 'Inferior' means below in position, 'Transverse' means situated across something, and 'Dorsal' refers to the upper side or back of a structure, making them incorrect in the context of the lower surface of a structure.

4. 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.

5. If someone is disseminating information, what are they doing?

A. Hiding it
B. Broadcasting it
C. Destroying it

Correct answer: B

Rationale: The correct answer is B: 'Broadcasting it.' Disseminating information means spreading or sharing it widely to reach a broader audience. Choice A, 'Hiding it,' is incorrect as disseminating involves making information known, not concealing it. Choice C, 'Destroying it,' is incorrect as disseminating means to distribute, not to eliminate. Choice D, 'Withholding it,' is incorrect because withholding information means keeping it back rather than sharing it openly.
