When the temperature of a gas is increased, it is either accompanied by an increase in pressure if the gas is enclosed in a container, or an increase in volume if the gas is able to expand.
(A) When the temperature of a gas is increased, it is either accompanied by an increase in pressure if the gas is enclosed in a container, or
(B) When the temperature of a gas is increased, it is accompanied either by an increase in pressure if it is enclosed in a container or
(C) When the temperature of a gas is increased, the increase is either accompanied by an increase in pressure if the gas is enclosed in a container or by
(D) Any increase in the temperature of a gas is either accompanied by an increase in pressure if it is enclosed in a container, or by
(E) Any increase in the temperature of a gas is accompanied either by an increase in pressure if the gas is enclosed in a container or by
原文意思：当气体温度升高的时候，温度伴随着压力的升高如果气体密闭在某个容器里或者伴随着体积增大如果气体能膨胀的话。
题目分析：原文有一个并列，就是温度伴随着A或者B，但是A either后面跟accompanied by 但是or后
面跟increase并不对应，干掉。B的either后面跟by而or后面直接是名词an increase，不行，干掉。C的either后面先跟动词再加by而or后面直接加by，不合适，干掉。D和C错误类似，干掉。E的either后面跟by并且or后面也跟by，比较对应，选E。
