题目分析：
本题主要考查了“比较”和一些词汇的用法。
选项分析：
A选项：比较对象的不对等。句首的in contrast to要求对比两者必须保证在逻辑上可比。能和“环境学员的方法”相对比的只能是“管理员们的方法”，不能是管理员本身。
B选项：本选项错误同选项(A)。
C选项：本选项错误同选项(A)。另外，本选项没有谓语动词。
D选项：分析本选项主干可知，其讲的是“administration's proposal是一个call”（此处，was是系动词，a call是名词，做表语）。但在逻辑上，应该是administration's proposal发出call for（需要）这个动作，即，管理员们的方法需要强制的限制，而不能说，管理员们的方法是一个call。
E选项：Correct. 本选项在语法和逻辑上均是正确的。
D. 主干变成了：(与environmentalists' proposals不同的是,) administration's proposal was a call. 错误
