LZ说的是这篇悦读么？？？

GWD5-Q35 to Q37: Even more thanmountainside slides of mud or snow, naturally occurring forest fires promotethe survival of aspen trees.  Aspens’need for fire may seem illogical (5) sinceaspens are particularly vulnerable to fires; whereas the bark of most trees consistsof dead cells, the aspen’s bark is a living, functioning tissue that—along withthe rest of the tree—succumbs quickly (10)to fire.
The explanation isthat each aspen, while appearing to exist separately as a single tree, is infact only the stem or shoot of a far larger organism.  A group of thousands of aspens can actually constitutea single organism, called a clone, that shares an interconnected root systemand a unique set of genes.  Thus, whenone aspen—a single stem—dies, the entire clone is affected.  While alive, a stem sends hormones into theroot system to suppress formation of further stems.  But when the stem dies, its hormone signalalso ceases.  If a clone (25) loses many stems simultaneously,the resulting hormonal imbalance triggers a huge increase in new, rapidlygrowing shoots that can outnumber the ones destroyed.  An aspen grove needs to (30) experience fire or some other disturbance regularly, or itwill fail to regenerate and spread. Instead, coniferous trees will invade the aspen grove’s borders and increasinglyblock out sunlight needed by the aspens.

----------------------------------------------------------------------

GWD5-Q35:
The primary purposeof the passage is to explain the
             
A.   qualities that make a particular organismunique
B.   evolutionary change undergone by aparticular organism
C.   reasons that a phenomenon benefits aparticular organism
D.   way in which two particular organismscompete for a resource
E.    means by which a particular organism hasbeen able to survive in a barren region
---------------------------------------------------------------------GWD5-Q36:
It can be inferredfrom the passage that when aspen groves experience a “disturbance” (line 30),such a disturbance
             
A.   leads to a hormonal imbalance within anaspen clone
B.   provides soil conditions that are favorablefor new shoots
C.   thins out aspen groves that have becomeoverly dense
D.   suppresses the formation of too many newaspen stems
E.    protects aspen groves by primarilydestroying coniferous trees rather than aspens
---------------------------------------------------------------------
GWD5-Q37:
The author of thepassage refers to “the bark of most trees” (line 6) most likely in order toemphasize the

A.   vulnerability of aspens to damage from firewhen compared to other trees
B.   rapidity with which trees other than aspenssuccumb to destruction by fire
C.   relatively great degree of difficulty withwhich aspens catch on fire when compared to other trees
D.   difference in appearance between the bark ofaspens and that of other trees
E.    benefits of fire to the survival of varioustypes of trees
