A study made by a psychologist shows that spending too much time in front of a computer causes insomnia. Two groups of adults took part in this study. During the study the first group spent 3 hours or less per day working on a computer; the second group spent 6 hours or more working on a computer. A greater proportion of the second group had trouble falling asleep during the period of the study than members from the first group.

Which of the following, if true of the adults in the study, most challenges the psychologist’s conclusion?

a) Some adults who spent more than 6 hours per day working on a computer had fewer problems falling asleep than others in the same group.

b) Some adults who spent 3 hours per day working on a computer did not have problems falling asleep.

c) Some adults voluntarily stopped spending too much time in front of a computer after the study.

d) Some adults spent time working on the computer without any breaks, while others took frequent breaks.

e) Many of the adults in the second group had problems falling asleep before the study began.

E is the only one, which seriously undermines the outcome of the analysis

First, reading the stem we know that this is a weaken type question. So think of some possible ways for the conclusion of this stimulus to be wrong.

Conclusion: >hours in front of computer >insomnia

Premise: People who spent >6 hours had more problems sleeping.

Which of the following, if true of the adults in the study, most challenges the psychologist’s conclusion?

a) Some adults who spent more than 6 hours per day working on a computer had fewer problems falling asleep than others in the same group - This doesn't negate the conclusion. So irrelevant.

b) Some adults who spent 3 hours per day working on a computer did not have problems falling asleep - This somewhat SUPPORTS the conclusion. Incorrect.

c) Some adults voluntarily stopped spending too much time in front of a computer after the study - This just disapproves the whole point of the study. Not correct.

d) Some adults spent time working on the computer without any breaks, while others took frequent breaks - This MIGHT seem like a correct answer, but do we know anything about how breaks affect sleeping tendencies? No. So incorrect.

e) Many of the adults in the second group had problems falling asleep before the study began. This is the only answer choice that directly talks about addressing a weakness in the structure of the argument. A preexisting condition would certainly render the results of the study useless. Hence correct.
