D

The argument assumes that getting married improved one's health. However, if single people with depression don't marry because of depression itself, then this suggests that depression itself is the actual cause of single people not getting marry.

C for me too...

I thinks that it is D.

In order to make such conclusion the author has to assume that "marriage" is a cause of "be happier and healthier" but not a sequence. People with depression or health problems might be reluctant to get marriage. If so, "marriage" is a effect.

OE:
Research indicates that there is a connection between being married and being happy and healthy. Media commentators have concluded that marriage causes happiness and health. However, one could reasonably conclude from the research that the cause and effect are the reverse: being happy and healthy makes a person more likely to get married.

(A) The research compared married people to unmarried people. Neither the researchers nor the media commentators made any distinction between newlyweds and those who had been married a long time, so this assumption is not necessary.

(B) The type of wedding is outside the scope of this argument. The research compared married people to unmarried people, but made no distinction based upon the type of wedding. Thus, this assumption is unnecessary.

(C) At first, this statement may seem necessary—after all, if the commentators conclude that marriage causes happiness, a lack of depression in married people would certainly support that conclusion. However, the statement is too extreme. One depressed married person does not invalidate the research indicating that, on average, married people are healthier and happier than non-married people.

(D) CORRECT. This statement eliminates the alternative interpretation of the research findings—that being happy and healthy makes a person more likely to get married.

(E) The research compared married people to unmarried people. Neither the researchers nor the media commentators made any distinction between harmonious marriages and combative marriages, so this assumption is not necessary.

My approach to CR question is first to determine the flaw in the argument (if the stimulus is an argument as oppose to statement of fact). Especially with an assumption question, the argument is most likely to be flaw. For instance, in this question, the flaw is correlation an causation. The commentator claims that just because there is a correlation between marriage and happiness + health benefits, you can conclude that marriage is good for your health and mental attitude.

As for me, I was down between C and D as well.

Answer choice D is correct because address this flaw in a very sneaky way. Choice D address this correlation and causation issue by eliminating the possibility that depression and health issue is actually causing people to NOT get married by saying that
" Single people with depression or health problems are just as likely to get married as are other single people."

If we negate answer choice D, then we'll see that the conclusion above does not hold. If we negate choice D, we'll get "Single people with depression or health problems are NOT AS LIKELY to get married as are other single people." This show that there are actually a reverse correlation between marriage and depression.


Answer choice C: is incorrect because as stated earlier, if we negate C. The conclusion still holds. This example might help for those of us who still think C is correct. What if I say that running 10 mile is a good for your cardio and fat loss, and some body (answer choice C) argues that runners cannot get fat, would this weakened my argument above. This is very similar to answer C on the question, just because you get married that doesn't mean that you will never be depressed. You might be happily marry for en year and then one day you found out that your husband or wife had an affair with your best friend. Furthermore, both of your parents are suffering from brain tumor. Any reasonable person would be depressed.

I like your reasoning. Awesome interpretation of "just as likely to get married "

A, B, C, E -> even when you negate them the argument wouldn't fall apart.
