Thepassage‘ssuggestionthatthetotalanaerobicenergyreservesofavertebrateareproportionaltothevertebrate'ssizeisbasedonwhichofthefollowingassumption?
A.largervertebratesconservemoreenergythansmallervertebrates
B.largervertebratesuselessoxygenperunitweightthansmallervertebrates
C.theabilityofavertebratetoconsumefoodisafunctionofitssize
D.theamountofmuscletissueinavertebrateisdirectlyrelatedtoitssize
E.thesizeofavertebrateisproportionaltothequantityofenergyitcanutilize
答案：E
解析：文本是关于无氧糖酵解产生能量的过程，且提出动物体积越大，所产生的能量储备也就越多。以恐龙为例，说明其遭遇攻击所能产生的能量之巨大。题干中问“thetotalanaerobicenergyreservesofavertebrateareproportionaltothevertebrate’ssize”这一论点是根据哪一条假定推断出来的，通读选项不难得出E。
