Question 17 • FL-1001420-AP English Language and Composition Sem 1 - Flex
The writer intends the passage to be read by a general audience. Which of the following sentences, if added after sentence 16, would best aid a reader’s understanding of the passage?
Answer
A
That is a catecholamine neurotransmitter located in the sympathetic ganglia, retina, and central nervous system.
B
That neurochemical creates reward-seeking loops, increasing goal-directed behavior.
C
That chemical signals that something feels good and urges behavior that will continue that pleasurable feeling.
D
It is produced by the substantia nigra and by the ventral tegmental area nearby.
Explanation
Choice C best helps a general audience because it explains the chemical’s effect in familiar terms: it signals pleasure and encourages behavior that may bring that pleasure again. Choice A uses technical terms such as “catecholamine” and “sympathetic ganglia,” while B and D rely on specialized scientific language without explaining the idea as plainly.
