In recent years the climate has been generally cool in
northern Asia. But during periods when the average
daily temperature and humidity in northern Asia were
slightly higher than their normal levels the yields of most
crops grown there increased significantly. In the next
century, the increased average daily temperature and
humidity attained during those periods are expected to
become the norm. Yet scientists predict that the yearly
yields of most of the region’s crops will decrease during
the next century.

Which one of the following, if true, most helps to resolve the apparent paradox in the information above?

(A) Crop yields in southern Asia are expected to remain constant even after the average daily temperature and humidity there increase from
recent levels.
(B) Any increases in temperature and humidity would be accompanied by higher levels of atmospheric carbon dioxide, which is vital to plant respiration.
(C) The climate in northern Asia has generally been too cool and dry in recent years for populations of many crop insect pests to become established.
(D) In many parts of Asia, the increased annual precipitation that would result from warmer and wetter climates would cause most edible plant
species to flourish.
(E) The recent climate of northern Asia prevents many crops from being farmed there during the winter.

I got this one right, but want to see if you guys have any explanations for the correct answer.

agree C. more pests --> less yield

It is C

The crops were high during previous SHORT spells of high temperature and humidity because generally the climate was dry and cool and POPULATIONS OF CROP INSECTS COULDN'T BECOME ESTABLISHED.

However, if the climate changes to continuously warm and humid these populations will establish themselves and thus will harm the crops

C is the only one that tells you why crop yeieds woiuld decrease. A adds no info to the argument and the rest all tell you why the yeilds should actually increase in the future
