Which of the following is NOT true of freshmen at Peking and Tsinghua Universiti

Every September, the campuses of Peking and Tsinghua Universities brim with eager new students, the winners of China’s cutthroat education system. These young men and women possess the outlook of cosmopolitan youth worldwide. They are destined for bright futures: In a few decades, they will fill high-powered positions in government and become executives in state banks and multinational companies. But their ever-expanding career possibilities belie the increasingly narrow slice of society they represent. The percentage of students at Peking University from rural origins, for example, has fallen to about 10 percent in the past decade, down from around 30 percent in the 1990s.
   China’s state education system, which offers nine years of compulsory schooling and admits students to colleges strictly through exam scores, is often hailed abroad as a paradigm for educational equity. But this reputation is built on a myth. While China has phenomenally expanded basic education for its people, quadrupling its output of college graduates in the past decade, it has also created a system that discriminates against its less wealthy and well-connected citizens, thwarting social mobility at every step with bureaucratic and financial barriers.
   A huge gap in educational opportunities between students from rural areas and those from cities is one of the main culprits. Some 60 million students in rural schools are "left-behind" children, cared for by their grandparents as their parents seek work in faraway cities.
