Now the Australia jumping spider as you can image got its name for its ability to leap. But it can swim too. What’s most interesting though is its ability to use try and error tactics when solving problems.

Now the jumping spider attacks and eats other spiders. It’ll sit at the edge of another spider's web and attract the spider by tapping out different signals to mimic the struggles of a trapped insect and later keep changing the signals till successfully lured its prey out. Well, to see if the jumping spider could apply the same problem solving technique try and error to unfamiliar situations, scientists conducted an experiment. They field a trap full of water and then put some sand in the middle, like an island. In between the island and the edge of the trap, they put a rock. When they put the spider on the island, some tried jumping to the rock, and some tried swimming. All the spiders that successfully reached the rock either by jumping or by swimming use the same method to make it from the rock to the edge of the tree. If the spider failed to reach the rock, it was placed back on the island, but the next time they try to leave, spiders did opposite of whatever didn’t work the first time, leaping if it had swum, or swimming if it had leaped. So we see the spiders using the same try and error in crossing the water as they used in hunting.

这道题我也为楼主的意见正确。“Now the jumping spider attacks and eats other spiders. It’ll sit at the edge of another spider's web and attract the spider by tapping out different signals to mimic the struggles of a trapped insect and later keep changing the signals till successfully lured its prey out.”

说的是  jumping spider 也吃其他蜘蛛。但它靠伪装成撞到了其他蜘蛛的蛛网上的昆虫来诱骗其他蜘蛛上钩。

选B的人可能是理解成了伪装成其他蜘蛛来骗那些其他撞上蛛网的昆虫，其实前面的“Now the jumping spider attacks and eats other spiders.”已经说明了下面要讲jumping spider 如何吃其他spider，所以楼主的思路应该正确。  

至于网上流传的托福答案么，除了早些年先的几次考试（已经被ETS在官方真题集上公布），基本都是靠大家集体琢磨的，部分题目答案的确存在争议。
