我是在复习破解版的prep，发现prep2 SC113题的题干有些不明白（我对答案没有疑义）

During the last interglacial period, the climate on the Earth was warmer than it is today,为何用it代替？此气候不是彼气候 and the consequent melting of the polar ice caps caused the sea level to raise about 60 feet over and above what its height presently is now.C

 

(A) sea level to raise about 60 feet over and above what its height presently is now

(B) sea level to be raised over its height presently about 60 feet

(C) sea level to rise about 60 feet above its present height

(D) level of the seas to rise over and above its present height about 60 feet

(E) level of the seas to be raised over their height, now about 60 feet

就是觉得During the last interglacial period, the climate on the Earth was warmer than it is today,为何用it代替？此气候不是彼气候
        

it应该用that代替。或者用其他的方式改写。

谢谢指教！
