TPO18 Reading: Lightning - 英檢

大家好! 想請問一下 下面這一題

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. 【Lightning that strikes the ground is
the most likely to be destructive】, so even though it represents
only 20 percent of all lightning, it has received a lot of
scientific attention.

The author mark "Lighting that strikes the ground is the most likely
to be destructive" in order to explain
(A) this form of lightning has been investigated so much
(B) this form of lightning is not as common as lightning within a cloud
(C) scientists understand of this form of lightning is important
(D) the buildup of positive charge on the ground beneath a storm cloud can
have serious consequence


爬文之後有看到有人問 但我還是有疑問

我的問題是修辭題看的是前句

這題答案會是A 是因為 even though... 被挪到後面的關係嗎?


感謝各位大大!!
