Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.

Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.

People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.

Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.

It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.

Hungry for the brightest students, many of the country's stronger universities are actively discounting tuition （学费）．And it's the high achievers, rather than the needy students, who are getting a good chunk of the money．The practice is remarkably widespread, reaching almost all but the 30 or so Ivy and other top colleges that forbid good grades-based financial aid．Schools are also becoming more aggressive in raising their discounts．At the DePauw University Website, enter an SAT or ACT score, grade point average and class rank, and a computer program immediately tells you what kind of "award"．Only "the real unlucky" pay full price any more．

About 76% of first-year students got some form of discount this year at 331 private schools．Average award per student: $7,000．At small schools with tuition under about $20,000, the average discount is even higher, with some schools returning over half their tuition．                                                          

Carnegie Mellon even tells students it will "negotiate（讨价还价）" and perhaps match financial-aid packages if kids are offered bigger awards at other schools．Much as banks and insurers offer special rates to their best customers, schools are giving the biggest breaks to their top students．Public four-year colleges, too, are offering discounts．

The flip side of big discounts is that less money is available to improve academic programs and keep school infrastructure （基础设施） up to date．Universities that have sharply increased their tuition discount rates have seen graduation rates fall, and that's true even among highly selective schools．They get the students in the door, but don't have the services to keep them．

From the first paragraph, we can judge that _______．

       A．all the universities don’t offer tuition discounts．

       B．Ivy and other top colleges offer financial aid to the high achievers

       C．the needy students get more money from the universities

       C．Public colleges never offer discounts to the students．
