Questions are based on the following passage．

Today， the poor aren "t just more likely to get divorced. They"re more likely to avoidmarriage entirely.

Earlier today， my colleague Derek Thompson argued that; it"s misleading to thinkof marriage as a "luxury good". Why? Because luxury goods are something the rich buyand the poor can"t afford. But in the case of marriage the trend is more complex. The vastmajority of Americans tie the knot at some point in their lives， he argues. It"s just thatthose without a college education are far， far more likely to get divorced. Marriage is foreveryone; failed marriages are for the poor.

Bleak stuff. But it"s getting bleaker.

Derek"s post is based on a long-term study of young Baby Boomers， who were atleast 46 years old by 2010. But among younger Americans， marriage really is lookingmore and more like something you"d have to buy at Tiffany"s. According to 2012 CensusBureau report， which shows the percentage of men who have never married by age andincome， the less a guy earns nowadays， the less likely they are to have ever gotten married.

Well， that"s not 100 percent true. Among twenty-somethings there seems to be arich bachelor effect going on （or an overworked young professional effect， if you prefer）.

Those making $75，000 or more are somewhat less likely to have been married than thosemaking between $40，000 and $75，000.

This particular set of Census data unfortunately tells us much less about women andmarriage. The problem: Stay-at-home morns.

The key to remember， though， is that many educated， high-earuing women， the sortswho are likely to meet and marry educated and high-earning men， leave the workforce orgo part time once they have children. So a publicist who once made over $70，000 a yearmight only earn $20，000 if she decided to work fewer hours while caring for her childrenat home.

Here"s why this trend——not just the move towards divorce like Derek talked about，but the move from nuptials （ 婚礼 ） entirely——is so gloomy. Getting married， and stayingmarried， is one of the surest ways of securing a middle class life. By choosing not to wedin the first place， the poor are abandoning that chance at stability.

Why doesn‘t Derek Thompson think that marriage is a luxury good? 查看材料

A.Because not everyone will get married eventually.

B.Because only rich people can afford to get married.

C.Because most people will get married regardless of their financial state.

D.Because lots of people can"t afford an expensive nuptial.
