[求助]LSAT-6-2-16

几个词组不太明白： all the more striking; make do; by large. 该题答案是E

16. The ancient Romans understood the principles of water power very well and in some outlying parts of their empire they made extensive and excellent use of water as an energy sources. This makes it all the more striking that the Romans made do without water power in dominated by large cities.

Which one of the following, if true , contributes most to an explanation of the difference described above in the Romans use of water power?

(A) The ancient Romans were adept at constructing and maintaining aqueducts that could carry quantities of water sufficient to supply large cities over considerable distances

(B) In the areas in which water power was not used water flow in rivers and streams was substantial throughout the year but nevertheless exhibited some seasonal variation

(C) Water power was relatively vulnerable to sabotage but any damage could be quickly and inexpensively repaired

(D) In most areas to which the use of water power was not extended other more traditional sources of energy continued to be used

(E) In heavily populated areas the introduction of water power would have been certain to cause social unrest by depriving large numbers of people of their livelihood

意思可能如下：

all the more striking: 愈加显著。

make d 凑合着做

by large: 大多数 （猜的）

在我的资料上,最后一句话是:This makes it all the more striking that the Romans made do without water power in regions dominated by large cities.

这篇RC怎么理解呀?

是说古罗马人早就掌握了water power的作用,他们早就能在偏远地区广泛并且出色运用水力资源作为energy source,(暗指那里水力资源比较丰富.),更为让人讶异常的是在那些缺乏水资源的大城市管辖的区域,人们也能利用水力资源来当energy sources

还是说偏远地区用水过多,反而让大城市那边没水用了尼

我觉得第一种理解比较对,可是如果这样的话,为什么选E不选A呢

原来是酱子啊!谢谢lawyer的指点,恍然大悟!!

原来还是没读懂……
