GWD5-Q36 求助！！！

jane.seeker

If a clone (25) loses many stems simultaneously, the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots that can outnumber the ones destroyed.  An aspen grove needs to (30) experience fire or some other disturbance regularly, or it will fail to regenerate and spread.  Instead, coniferous trees will invade the aspen grove’s borders and increasingly block out sunlight needed by the aspens.


GWD5-Q36:
It can be inferred from the passage that when aspen groves experience a “disturbance” (line 30), such a disturbance

A. leads to a hormonal imbalance within an aspen clone
B. provides soil conditions that are favorable for new shoots
C. thins out aspen groves that have become overly dense
D. suppresses the formation of too many new aspen stems
E. protects aspen groves by primarily destroying coniferous trees rather than aspens

答案是A，我选了E。从（30）开始定位思来想去都是E呀，求大神指点！！

怎么会是E呢？

前边已经说了，当同时……，就会大量生长。 aspen groves experience a “disturbance.就是同时呼应前边loses many stems。
文中也说了如果它不experience fire or some other disturbance。它就会停止生长，并且instead . coniferous trees will invade the aspen grove’s borders

E中并不是火烧坏了coniferous trees 保护了aspen.    而是火烧刺激了aspen的生长，使得它不被coniferous trees 遮盖。
