Studies have shown that levels of depression among those diagnosed with clinical depression actually increase in the springtime. The results of the studies were no different for subjects who spent most of their days outdoors than for those who stayed indoors. Researchers, once baffled by this finding, now hypothesize that seasonal changes in the mental health of the most severely depressed can be based on more than exposure to light.

Which of the following, if true, would most strengthen the researchers' hypothesis?

A. The same subjects evidence no change in mental health in the autumn when the amount of light is equivalent to that in spring.

B. As all people inherently believe that their health will improve in the spring, the unrealized expectation of improved health will often lead the most depressed to an even deeper level of depression.

C. Healthy subjects report feeling more alert and happy in the springtime as compared with the winter.

D. Seasonal-affective disorder (SAD) affects nearly one in ten people and can seriously interfere with an individual's work schedule and lifestyle habits.

E. Other scientists have demonstrated how over-exposure to sunshine can deplete the brain of the neurochemical seratonin and result in higher levels of depression.

P1 : Depression increases during spring. P2 : Depression same indoor and outdoors.
Conclusion : Depression therefore doesnt not depend on only exposure. I.e there is more than one cause for the effect.

Pre-thinking : Statement citing any other cause for the effect.

Therefore Answer B is right.

is n't E a weakener?

Argument trying to say another cause for the effect (depression), but E -> Other scientists say more exposure to light -> depression.

Hi Prashant10692,

As explained in the post above this one, E weakens the author's point because it supports the idea that light is the main factor. We are looking for an alternative explanation, and B gives us that answer.

Studies have shown that levels of depression among those diagnosed with clinical depression actually increase in the springtime. The results of the studies were no different for subjects who spent most of their days outdoors than for those who stayed indoors. Researchers, once baffled by this finding, now hypothesize that seasonal changes in the mental health of the most severely depressed can be based on more than exposure to light.

Does this help?

The author concludes that increased depression in the springtime among the most severely depressed patients has a cause other than exposure to light. The evidence is a study that found depression worsened in the spring with no change in depression level between people who were outdoors or indoors.

Predict the Answer:

The author never suggests what might be the cause, so is assuming there's another cause that has no connection to light exposure. The correct answer will be anything that makes the Assumption more likely. Look for a choice that indicates there may be a cause other than light for the springtime depression.

Evaluate the Answers:

(B) is correct. It strengthens the idea that light is not the cause by suggesting an alternate cause: unmet health expectations.

(A) is irrelevant. It focuses on light, but the conclusion indicates there is a cause other than light.

(C) is irrelevant as it focused on healthy subjects, not depressed ones.

(D) is irrelevant since it describes a particular condition but does not address the cause of that condition.

(E) weakens the conclusion by offering a possible explanation for worsening mental health in the spring based on exposure to light.

The question is about strengthen the argument but this option is opposite and weakens the argument...This option is stating that exposure to light is the cause of depression but in conclusion author mentioned that there are other causes of depression but not sunlight
I hope its clear

Option 'A' again iterates that the depression is caused by light, whereas the hypothesis says that there's something other than exposure to light that is causing seasonal depression.

Therefore the answer which says anyother reason apart from light will be correct.

Hope this helped !

Have to be very careful when one is reading a CR passage.

Here the last line says " most severely depressed can be based on more than exposure to light"

A kinda strengthens it says " The same subjects evidence no change in mental health in the autumn when the amount of light is equivalent to that in spring" but B is better

as it says As all people inherently believe that their health will improve in the spring, the unrealized expectation of improved health will often lead the most depressed to an even deeper level of depression" gives a alternate reason.
