文章：
In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have signifi cant barnacle populations, even though they seldom burrow.
题目：
Which of the following, if true, most helps to explain the surprising fi nding?
选项:
A、Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest
B、The strength of the tidal currents in a given location varies widely over the course of a day.
C、A very large barnacle population can signifi cantly decrease the ability of a horseshoe crab to fi nd food
D、Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year.
答案:
E

我选了B，我的思路是题目最后说的是tidal current和 barnacle的事情，我就直接排除了CDE，。。老师还有救吗

提问：
想请老师解释一下A为什么错，感觉A能聊得下去，A不是海浪自己把B从螃蟹上弄走的（我的思路：之前能抵挡海浪，现在海浪小了却没有Barnacles了——矛盾了，所以和海浪没关系）
