Recent research has indicated that married people are not only happier than unmarried people, but also healthier. This study has been widely reported by the media, with most commentators concluding that being married is good for one's health and attitude.

The conclusion of the media commentators depends on which of the following assumptions?

(A) The longer people are married, the happier and healthier they become.
(B) Married couples who had a large, extravagant wedding are happier than those who had a small, simple one.
(C) Married people cannot get depressed.
(D) Single people with depression or health problems are just as likely to get married as are other single people.
(E) Some marriages are more harmonious than others.



OA says this :-


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

what's wrong with C???!!!

I will go with D. If you negate D, you will get: People who are healthy and depression-free are more likely to get married.

If this is true, then the conclusion that 'being married is good for one's health and attitude' is simply not true.

Conclusion: Being married -> Happy life.
So one has to assume that reverse is not true.

Negation of C, simply wont harm the conclusion. Conclusion says that married people are happier than unmarried; it doesn't say married people are ALWAYS happy.

Vinayak,

[spoiler]I will go with D. If you negate D, you will get: People who are healthy and depression-free are more likely to get married. [/spoiler]

Dont agree with the above.
Negation of D would be

Single people with depression or health problems are not just as likely to get married as are other single people

In this case, the research would be invalid as the research only includes people who marry and those who marry would be healthy people. So conclusion breaks.

Negation of = cant be more always .. it can be less also.
Regards,
Sach

You're right. I didn't write the exact negation. It was more of a gist of the negation.
