参考答案

正确答案：B
解析：同样在第十一段，President Bush used the report as a basis for Reading First, a program to improve reading scores that became the centerpiece of his No Child Left Behind law，该法律的核心问题是Reading First program，而后者的基础是report by the National Reading Panel，根据第三题可以知道，报告的内容是片面的，所以No Child Left Behind Law的核心问题是不够全面，所以选B。
