请教一个指代的问题

问题描述

In fact, according to developmental psychologist David Elkind, United States society tends to push children so rapidly that they begin to feel stress and pressure at a young age. According to Elkind, not only does this cause the child emotional distress, it also fails to bring the intended cognitive gains.第2句的this指代什么？是push children so rapidly还是feel stress and pressure at a young age？

老师答疑

王老师：

这也是托福TPO阅读练习中的句子。第二句的this当然指代push children so rapidly了。如果指代feel stress and pressure at a young age，根据上下文，似乎不太合乎逻辑。
