比如：
SC01519中，
原句是：Global warming is said to be responsible for extreme weather changes, which, like the heavv rains that caused more than $2 billion in damages and led to flooding throughout the state of California, and the heat wave in the northeastern and midwestem United States, which was also the cause of a great amount of damage and destruction.
正确答案是：such as the heavy rains that led to flooding throughout the state of California, causing more than $2 billion in damages
这里的causing跳过了preposition phrase，直接修饰flooding我可以理解
但是另有一句：SC01594中
原句是：Butterflies come in more than 17,000 species, displaying a wing pattern unique to each one.
正确答案是：each of which displays a unique wing pattern
我想请问为什么原句中的不对呢？同样是verbing+ing，这里的displaying也应该可以修饰species，但是书上的解释是displaying修饰butterflies，所以我不太明白，还望赐教，多谢各位了！
