逻辑OG17新题 第549题
During the earliest period of industrialization in Britain, steam engines were more expensive to build and operate than either windmills or water mills, the other practicable sources of power for factories. Yet despite their significant cost disadvantage, steam-powered factories were built in large numbers well before technical improvements brought their cost down. Furthermore, they were built even in regions where geographical conditions permitted the construction of wind- and water-powered factories close to major markets.

Which of the following, if true, most helps to explain the proliferation of steam-powered factories during the earliest period of industrialization in Britain?
A. In many areas of Britain, there were fewer steam-powered factories than wind- or water-powered factories in the earliest period of industrialization.
B. Unlike wind- or water-powered factories, steam-powered factories were fueled with coal, which sometimes had to be transported significant distances from the mine to the site of the factory.
C. It was both difficult and expensive to convert a factory from wind power or water power to steam power.
D. In the early period of industrialization, many goods sold in towns and cities could not be mass-produced in factories.
E. In Britain, the number of sites where a wind- or water-powered factory could be built was insufficient to provide for all of the demand for factory-produced goods at the time.


正确答案E
我的疑问是:答案E的意思是
“(因为)能修建风车和水磨的地方数量不够,这些工厂生产的产品数量不足以满足市场需求(所以工厂宁愿付出更高的成本也要用蒸汽机作为动力来源)”
这不是和题干里的信息“即便在地理条件允许修建风车和水磨的地方也有蒸汽驱动的工厂存在”相矛盾吗?

是不是我理解的意思有问题呢?请NN们请教!

OG解释如下,供参考:
Situation
Although steam engines were more expensive than windmills and water mills in early industrial Britain, many steam-powered factories were built even in regions where the construction of wind- and water-powered factories was geographically feasible.
Reasoning
Why might steam-powered factories have proliferated despite their cost disadvantage? Early industrialists would have needed some positive reason to choose steam over less expensive power sources for their factories. For example, steam engines might have operated faster or more effectively than windmills or water mills. Or steam engines might have received government subsidies. Or conditions restricting the number or locations of windmills and water mills might have forced industrialists to use steam power instead.
A   This suggests that the steam-powered factories did not initially proliferate as widely as they might have, but it does not explain why they proliferated to the extent that they did.
B   The inconvenience of transporting coal for steam-powered factories would have made those factories less likely to proliferate, not more likely.
C   The difficulty of converting factories to steam power would have made steam-powered factories less likely to proliferate, not more likely.
D   The technological inability to mass-produce popular products in factories would have made factories in general less likely to proliferate, including steam-powered factories.
E   Correct. The inadequate number of sites for wind- and water-powered factories might have encouraged early industrialists to build steam-powered factories instead, since the high demand for factory-produced goods could have made these factories profitable despite their cost disadvantage.

看了五个选项只有E是对的,不矛盾啊,是说能建的最多数量的风力水电还是不能满足需求,所以需要Steam engine,我这样想的

谢谢,我再琢磨琢磨

我的理解是这样的,问题要求你解释为什么蒸汽机会扩建。原文有一个gap,就是明明蒸汽机的cost很高,却被大量扩建,还是在没有科技进步降低cost的情况下。yet前面的信息高速我们如果cost很高,那么一般是不会建蒸汽机发电的,要建也是建water或者wind厂。但是现在蒸汽机不仅被建了,还被建在一般建water跟wind发电厂的旁边。那么就可能是有除去cost的其他原因导致不得不建,而且有可能在wind跟water解决不了的情况下。

我一開始的思路也跟樓主一樣,但我覺得可以分兩個層次來選出(E)

1. Argument:. Yet despite their significant cost disadvantage, steam-powered factories were built in large numbers well before technical improvements brought their cost down.
論點是針對 蒸汽廠(role)  儘管成本較高 仍被 "大量"(整體) 建造(Topic)

(A)選項是說In many areas of Britain(部分) 且將蒸氣廠數量和水/風發電廠做比較 但並不足以說明成本高卻仍被建造的事實

再看2. Premise II可以理解為(1)蒸氣場在被允許建造(可能是指政府規範/建造條件)水/風的地方
但並沒有說是否能有足夠的產出,因為像水力發電是有自然資源的限制的
其次(2)限定修飾語 close to major markets 並不足以說明整體都是如此

而(E)選項提及的他因"demand for factory-produced goods"足以解釋 即使水/風力發電廠即使在可以建的地方都建了 但仍不足以提供電力所需 (具體原因可能是自然資源限制,也有可能是生產效率)
