(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.
I think none of the reasoning came even close to justify D as the correct answer, not even the "official explanation". Thank God, that the other options were so nonsensical that POE came in handy.
Justification :
Let's assume two people and name them Mr. Single-depressed and Single-happy.According to the research, there is a group called Married-Happier, which only contains happy people. The research doesn't say this explicitly, but implies that there is no group called Unhappy-Married.
Let's see what happens to them after marriage and decide would they want to get married?
Single-depressed -> married-happier
Single-happy -> married-happier.
The increase in happiness sure is a reason to get married for both.
Had the group's name been Married-Happy:
Single-depressed -> Married-happy
He will want to get married as he wants to be in a better state.
But,
Single-Happy -> Married-happy.
why would he get married, if he can remain happy while being single ?
For the simple reason : "the research says that he'll be happier even if his second name remains the same "
Hence, the commentators assume that there are as many single-happy people as there are single-depressed in the group and all have become happier after they got married. Hence, makes a generalization (conclusion) for all the unmarried people.
The commentator's couldn't have generalized for all the singles, had the single-happy people been less than single -depressed in the group.
