请教一道短阅读题

Anaerobic glycolysis is a process in which energy is
produced, without oxygen, through the breakdown of
muscle glycogen into lactic acid and adenosine tri-
Line phosphate (ATP), the energy provider. The amount
5 of energy that can be produced anaerobically is a
function of the amount of glycogen present—in all
vertebrates about 0.5 percent of their muscles‘ wet
weight. Thus the anaerobic energy reserves of a verte-
brate are proportional to the size of the animal. If, for
10 example, some predators had attacked a 100-ton
dinosaur, normally torpid, the dinosaur would have
been able to generate almost instantaneously, via
anaerobic glycolysis, the energy of 3,000 humans at
maximum oxidative metabolic energy production.

The passage‘s suggestion that the total anaerobic
energy reserves of a vertebrate are proportional to the
vertebrate‘s size is based on which of the following
assumption?
(A) larger vertebrates conserve more energy
than smaller vertebrates
(B) larger vertebrates use less oxygen per unit
weight than smaller vertebrates
(C) the ability of a vertebrate to consume food
is a function of its size
(D) the amount of muscle tissue in a vertebrate
is directly related to its size
(E) the size of a vertebrate is proportional to
the quantity of energy it can utilize




答案选D我选的是A，原文不是说到“Thus the anaerobic energy reserves of a verte-
brate are proportional to the size of the animal. ”，那跟D选项的muscle tissue有什么关系呢，还请大大解释下，多谢！！！！！

A选项中的energy没有具体的限定，而题目中与体型成正比的是anaerobic energy，文章中也没有说明这种特定的energy于总体上没有限定的energy成正比例关系。

in all vertebrates about 0.5 percent of their muscles‘ wet weight. Thus the anaerobic energy reserves of a vertebrate are proportional to the size of the animal.
vertebrates 中5%为muscles‘ wet weight。
vertebrate are proportional to the size 。

同意楼上。LZ定位的句子差不多，但离完美还差一步。
注意到句首有个thus，就说明原因应该是前面，本文即前一句。所以真正要定位的以下这句：
The amount of energy that can be produced anaerobically is a function of the amount of glycogen present—in all vertebrates about 0.5 percent of their muscles‘ wet weight.
同义改写即A。
