questions 10 through 13 refer to the following.
(the passage below is a draft.)
(1) if you have ever felt overwhelmed by the barrage of e-mails, text messages, and social media notifications you receive every day, you are not alone. (2) unsurprisingly,
neuroscientists warn that the constant use of smartphones alters the brain.
(3) what people can’t resist immediately checking their phones each time they buzz, chirp, or
chime, and scientists believe that compulsion is caused by a brain chemical called
dopamine. (4) the release of dopamine in the brain is pleasurable, so people tend to repeat
behaviors that trigger it. (5) researchers studying the effects of smartphone use found that
each time people received a phone notification, their brains had a surge of dopamine. (6)
curiously, the anticipation of a reward (signaled by each ding of the phone) caused more
pleasure than the reward itself (the e-mail or social media alert). (7) our brains are aroused
each time our phones buzz because of the unpredictability of what pops up on the screen.
since any alert might signal something extraordinary, dopamine is released each time even
though most alerts don’t amount to much.
(8) while dopamine rewards may cause the brain to crave these constant phone alerts, their
effects on the body are harmful. (9) the incessant notifications cause the heart to beat
faster, muscles to tighten, and breathing to get shorter—a fight-or-flight response. (10) and
when we live in a perpetual state of stress, our prefrontal cortex, the part of the brain that
controls reasoning, stops functioning properly. (11) a vicious cycle ensues: people become
addicted to constant phone interruptions even as those interruptions put stress on the body.
the writer is considering deleting the underlined portion of sentence 7 (reproduced below),
adjusting the punctuation as needed.
our brains are aroused each time our phones buzz because of the unpredictability of what
pops up on the screen since any alert might signal something extraordinary, dopamine is
released each time even though most alerts don’t amount to much.
should the writer keep or delete the underlined text?
a keep it, because it adds information that helps clarify the
contrasting relationship identified in sentence 6 between
anticipation and reward.
b keep it, because it provides evidence suggesting that
smartphones cause social impairments in individuals who use
them.
c delete it, because it does not follow logically from sentence 7’s

Accepted Answer

# Brief Explanations:
Sentence 7 states that "our brains are aroused each time our phones buzz because of the unpredictability of what pops up on the screen". Sentence 6 mentions that "each time people received a phone notification, their brains had a surge of dopamine". The underlined text "anticipation and reward" connects the idea of the brain's response (anticipation of what's on the screen - reward of dopamine surge) in a concise way that links the two sentences. Options B and C are incorrect as they either introduce new, un - related concepts (social impairments in B) or are not relevant to the logical flow between sentence 6 and 7 (deletion in C).

# Answer:
A. Keep it, because it adds information that helps clarify the contrasting relationship identified in sentence 6 between anticipation and reward.
