12.Look at the four squares [[span class='strong-insert']][[/span]] that indicate where the following sentence could be added to the passage. Where would the sentence best fit?
These sudden floods provide important water supplies but can also be highly destructive.
C，三个过渡点，分别是代词these，名词water supplies和名词flood，flood与原文第四段最后一句的large flows of water是同义词，所以B或者C可能对，但these能够确定C对，因为these flood之前必须有说到flood的，刚好前面的large flows of water满足要求。
