Ms. Chambers is among the forecasters who predict that the rate of addition to arable lands will drop while those of loss rise.
(A) those of loss rise
(B) it rises for loss
(C) those of losses rise
(D) the rate of loss rises
(E) there are rises for the rate of loss
No problem with the correct choice D. But just a sense of confusion, can experts shed some lights on the problems that the "rises" is in simple present? ( but not future tense just like "will drop")
is it has something to do with the meaning or the usage of "while" ? Thank you
