为修复龋齿而制备出的牙洞，固然是古代人了不起的成就，但是这并不表示当时的人们对这种疾病的理解有多么深刻：看到龋齿的形态和被虫蚁啃噬之后的木材很类似，他们推断，在口腔里有一种叫做“牙虫”的虫子，像白蚁啃噬木头那样侵蚀我们的牙齿。很可能是因为白蚁的危害遍及全球，这个理论出现在所有的古代文明里，包括两河流域、古印度、古埃及以及古代中国。 通过本段文字不能够得出的信息是( )。

The Bush administration is considering an audit of the national school lunch program to make sure that all the children receiving free and reduced-price lunches come from families that are truly low-income. The Department of Agriculture says about 28 million children get their lunch each day through the program, which cost 68 billion in 2002. A USDA study last year estimated that one in five children participating might be ineligible because the family’s income is too high. USDA estimates that 10 billion of the funding bought lunches for ineligible children. A family of four with an annual income of up to 23,530 qualify for free meals. Families that make 33,485 qualify for reduced-price lunches costing up to 40 cents. Administration officials and lawmakers say they’re trying to keep recipients honest while not scaring away needy families. What happens with the program won’t just affect how many children receive free chicken nuggets, chocolate milk and canned fruit salad. States and school districts use the program figures to estimate poverty levels at schools, so the results also could affect the amount of government aid at all levels that makes its way down to struggling schools. Schools rely on parents to report their income but generally don’t require proof. "When you start tightening up the scrutiny on these applications, families become fearful and they don’t ap ply," says Gaye Lynn MacDonald of the school food service association. Eligible children took ______ billion of the funding in 2002.
