Most lightning takes place within a cloud when the charge separation within the cloud collapses.However,as the storm cloud develops,the ground beneath the cloud becomes positively charged and lightning can take place in the form of an electrical discharge between the negative charge of the cloud and the positively charged ground.so even though it represents only 20 percent of all lightning,it has received a lot of scientific attention.
题目问作者为什么提到【Lightning that strikes the ground is the most likely to be destructive】,
我选的选项是：explain why scientific of this form of lightning is very important
正确答案是：explain why this form of lightning has been investigated so much
我想请问一下这俩有啥区别么?为什么不是我那个答案?

首先你的Lightning that strikes the ground is the most likely to be destructive没在这段中,应该在上一段吧.
至于答案,我想是因为最后一句even though it represents only 20 percent of all lightning,it has received a lot of scientific attention..它是想强调因为闪电如此,尽管这种类型的闪电只有百分之二十,但它仍然吸引了大量的注意,所以有大量的研究.而不是你选的重要.
