单选题 The most important divide in America today is class, not race, and the place where it matters most is in the home. Conservatives have been banging on about family breakdown for decades. Now one of the nation's most prominent liberal scholars has joined the chorus. Robert Putnam is a former dean of Harvard's Kennedy School of Government and the author of Bowling Alone (2000), an influential work that lamented the decline of social capital in America. In his new book, Our Kids, he describes the growing gulf between how the rich and the poor raise their children. Among the educated elite the traditional family is thriving: fewer than 10% of births to female college graduates are outside marriage—a figure that is barely higher than it was in 1970. In 2007 among women with just a high-school education, by contrast, 65% of births were non-marital. Race makes a difference: only 2% of births to white college graduates are out-of-wedlock, compared with 80% among African-Americans with no more than a high-school education, but neither of these figures has changed much since the 1970s. However, the non-marital birth proportion among high-school-educated whites has quadrupled, to 50%, and the same figure for college-educated blacks has fallen by a third, to 25%. Thus the class divide is growing even as the racial gap is shrinking. Upbringing affects opportunity. Upper-middle-class homes are not only richer (with two professional incomes) and more stable; they are also more nurturing. In the 1970s, there were practically no class differences in the amount of time that parents spent talking, reading and playing with toddlers. Now the children of college-educated parents receive 50% more of what Mr. Putnam calls 'Goodnight Moon' time (after a popular book for infants). Working-class parents, who have less spare capacity, are more likely to demand that their kids simply obey them. In the short run this saves time; in the long run it prevents the kids from learning to organize their own lives or think for themselves. Poor parenting is thus a barrier to social mobility, and is becoming more so as the world grows more complex and the rewards for superior cognitive skills increase. Stunningly, Mr. Putnam finds that family background is a better predictor of whether or not a child will graduate from university than 8th-grade test scores. Kids in the richest quarter with low test scores are as likely to make it through college as kids in the poorest quarter with high scores. Mr. Putnam suggests a grab-bag of policies to help poor kids reach their potential, such as raising subsidies for poor families, teaching them better parenting skills, improving nursery care and making after-school baseball clubs free. He urges all 50 states to experiment to find out what works. A problem this complex has no simple solution.

单选题Virtually all consumers will have a credit card in their lives. Selecting a credit card should not be something taken lightly, card companies are constantly looking for new consumers, but only after wisely comparing offers should you select a provider. Pick a company that will give you a reasonable rate and one that incentivizes their program with some type of reward for using their card. Almost without fail, rewards cards typically give consumers money back on their purchases or allow you to accumulate points toward prizes on future purchases. If you charge $10,000 per year and your rewards card pays you a 2% reward on purchases, you will receive $200 from the company. Usually you will gain the funds in the form of several credits to your account spread out over the course of year, but in some cases you will receive the rewards in the form of a check. Rewards cards are free money? Only if you do not have to pay an annual fee and you pay your credit card off every month. If you do not pay your card off every month, your reward could easily be overshadowed by monthly interest payments, especially if your interest rate is high. Not too many companies pay rewards and give you a low rate at the same time. In theory, even if you carry balances for as little as 2-3 months before paying your card off you could find your rewards for the entire year outweighed by finance charges. So you need to consider the following when selecting your card. First, is there an annual cap on purchases? Many rewards cards will limit to you the amount of cash back funds or rewards points you can accumulate in one year. Most people never come close to the figure, but if you are a business traveler you can quickly approach and pass these limitations within the year. Second, do points eventually drop off? The majority of rewards cards only allow you to accumulate points for three years before they begin to drop off. If your next car purchase is five years away and you have a program that drops off points, you could find the first two years of card usage to be a waste as those points would vanish. If you still want that particular rewards card, only use it in years 3, 4, and 5 so that when it comes time to purchase your new car you will not have lost any points. You could consider getting and using another rewards card for a different rewards system to cover years 1 and 2. All in all, rewards card can be a useful option for the savvy consumer. Remember, points do fall off and carrying balances from month to month will wipe out the value of the card in short order. By showing plenty of discipline you can make rewards cards work well for you.
