Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while those of loss rise.
those of loss rise
it rises for loss
those of losses rise
the rate of loss rises
there are rises for the rate of loss
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
A选项：those指代不明确，要是指代the rate 也应该用单数that;
B选项：说不通的句子；
C选项：同A选项的错误；同时of losses也应该是单数，同addition平行；
E选项：多么尴尬的表达啊，啰哩啰嗦的，必错
while前的比较对象是 (the rate) of (addition to arable lands) will (drop)， = the rate of sth+动词while后面也应该是这种结构.B项：it rises for loss = it（the rate）+动词+介词+sth
不平行
