削弱题目

Metropolis regulation limiting to 4 days the period during which milk can be sold to consumers after pasteurization is unreasonable. Under optimal conditions,pasteurized milk kept at 40 degrees Fahrenheit remains unspoiled for at lease 14 days.If Metropolis current limitation were changed to 8 days,milk prices would drop,but product quality would be unaffected.

E  In Metropolis,conditions for handling and storing milk after pasteurization are seldom close to optimal.

能否解释一下为什么选E啊

原文说，杀菌之后，在optimal的情况下，牛奶可以在40度的状态下保质14天

E说，在Metropolis，杀菌后，处理和保存牛奶的条件很少能达到optimal，也就是在M，牛奶通常不能保质14天，也就是说，原文说的limitation是reasonable的，也就是削弱了原本的“..... is unreasonable”这个论断。
