Along the major rivers that traverse the deserts of northeast Africa, the Middle East, and northwest India, the combination of a reliable supply of water and good growing conditions both encouraged farming traditions that, in places, endure in at least 6,000 years.
(A) good growing conditions both encouraged farming traditions that, in places, endure in
(B) good growing conditions encouraged farming traditions that have, in places, endured for
(C) of good growing conditions have encouraged farming traditions that, in places, endured for
(D) of good growing conditions both encouraged farming traditions that have, in places, endured
(E) of good growing conditions encouraged farming traditions that have, in places, been enduring for
我想要请问 E 除了 combination of X and Y 错误之外，为什么用have been enduring
是错的呢？ 因为为他说endure in at least 6,000 years 持续了6000年 到现在并没有
不确定有没有停止，所以我不知道该从哪里判断用现在完成式会比现在完成进行式好
谢谢
