It was once accepted as fact that the cutting occurred gradually, as the glacier melted. But one geologist theorized that the channels were cut in a short time by an enormousflood. The channels do show physical evidence of having been formed quickly, but the flood theory was originally rejected because scientists knew of no natural process that could melt so much ice so quickly. Paradoxically, today the scientific community accepts the flood theory even though scientists still do not know of a process that can melt so much ice so quickly.

Which one of the following is supported by the information in the passage?

(A)Only running water can cause deepchannels in volcanic rock. - WRONG. Bit extreme claim to make. 

(B) The river did not existbefore the channels were cut. - WRONG. Again like A a
