e- Insects that develop a tolerance for feeding on a plant that had previously been toxic to them, and the resultant changes within that plant species，feeding on a plant that had previously been toxic to them= "antiherbivore chemistry"
a选项- problem指“不同的企业受到环境法规的影响不同”，但是看下半句，作者并没有就解决这个问题给出办法，即如何解决受到环境法规影响不同；作者基于承认这个问题存在的基础上，就如何应对环境法规给出建议，因此suggest possible solutions（to this problem）不正确，文中没有提及
e选项-文中第一句”所有企业收到影响相同“，下一句”实际上企业收到的影响不同“，并给出三点理由（For example, additionally，moreover，）
deregulation of the airlines in 1978 — changes that included 【dramatic growth in the corporate demand for travel services】, as well as extensive restructuring and consolidation within the travel industry
C项不是deregulation导致的effect，而是那个agent应对change所采取的措施（从而成为a survivor of the change）。
