Columnist: There are several symptoms of depression. One symptom is sleeping more than 12 hours a day. Therefore, you should buy an alarm clock so that you do not sleep more than 8 hours a day to cure your depression.

If the article also noted that excessive sleeping is caused by reduced serotonin levels resulting from depression, then which of the arguments below best describes the logical flaw in the columnist’s reasoning?
A. Sleep has many beneficial effects.
B. The columnist has mistaken an argument for an explanation.
C. The columnist has mistaken a premise for a conclusion.
D. The columnist has failed to consider that an alarm clock may not be a reliable means of assuring a person wakes up.
E. The columnist has mistaken a symptom for a cause.

This critical reasoning question confuses the order of causation. If depression (x) causes reduced serotonin levels (y), and reduced serotonin levels (y) cause a person to sleep excessively (z), then depression ultimately causes a person to sleep excessively (x-->y-->z). The argument is stating that you should buy an alarm clock to eliminate z, and thus eliminate your depression (x). As we can see from the flow chart, eliminating z will not eliminate x...the order is backwards. This argument therefore mistakes a symptom (aka a result) for a cause, making answer choice E correct.

I hope this helps!!!
