OG-6-35突然又绕不过来了！

In the two decades between 1910 and 1930, over

ten percent to the Black population of the United States

left the South, where the preponderance of the Black

population had been located, and migrated to northern

(5) states, with the largest number moving, it is claimed,

between 1916 and 1918. It has been frequently assumed,

but not proved, that the majority of the migrants in

what has come to be called the Great Migration came

from rural areas and were motivated by two concurrent

(10) factors: the collapse of the cotton industry following

the boll weevil infestation, which began in 1898, and

increased demand in the North for labor following

the cessation of European immigration caused by the

outbreak of the First World War in 1914. This assump-

(15) tion has led to the conclusion that the migrants’ subse-

quent lack of economic mobility in the North is tied to

rural background, a background that implies unfamil-

iarity with urban living and a lack of industrial skills.

But the question of who actually left the South has

(20) never been rigorously investigated. Although numerous

investigations document an exodus from rural southern

areas to southern cities prior to the Great Migration.

no one has considered whether the same migrants then

moved on to northern cities. In 1910 over 600,000

(25) Black workers, or ten percent of the Black work force,

reported themselves to be engaged in “manufacturing

and mechanical pursuits,” the federal census category

roughly encompassing the entire industrial sector. The

Great Migration could easily have been made up entirely

(30) of this group and their families. It is perhaps surprising

to argue that an employed population could be enticed

to move, but an explanation lies in the labor conditions

then prevalent in the South.

About thirty-five percent of the urban Black popu-

(35) lation in the South was engaged in skilled trades. Some

were from the old artisan class of slavery-blacksmiths.

masons, carpenters-which had had a monopoly of

certain trades, but they were gradually being pushed

out by competition, mechanization, and obsolescence,

(40) The remaining sixty-five percent, more recently urban-

ized, worked in newly developed industries---tobacco.

lumber, coal and iron manufacture, and railroads.

Wages in the South, however, were low, and Black

workers were aware, through labor recruiters and the

(45)Black press, that they could earn more even as unskilled

workers in the North than they could as artisans in the

South. After the boll weevil infestation, urban Black

workers faced competition from the continuing influx

of both Black and White rural workers, who were driven

(50) to undercut the wages formerly paid for industrial jobs.

Thus, a move north would be seen as advantageous

to a group that was already urbanized and steadily

employed, and the easy conclusion tying their subse-

quent economic problems in the North to their rural

background comes into question.

35. It can be inferred from the passage that the “easy conclusion” mentioned in line 53 is based on which of the following assumptions?

(A) People who migrate from rural areas to large cities usually do so for economic reasons.

(B) Most people who leave rural areas to take jobs in cities return to rural areas as soon as it is financially possible for them to do so.

(C) People with rural backgrounds are less likely to succeed economically in cities than are those with urban backgrounds.

(D) Most people who were once skilled workers are not willing to work as unskilled workers.

(E) People who migrate from their birthplaces to other regions of country seldom undertake a second migration.

这是第二遍看了，我知道答案是C，就是把前面的假设改写了。但是看到这儿忽然觉得哪儿好像没绕过来，文章开头说大多数认为“GREAT MIGRATION”都是RURAL， 因为他们后来的经济问题，但是作者说移民都是URBAN，然后论证了半天，最后说人家的结论：“把后来的经济问题和农村背景联系起来”是有问题的。但是给我的感觉好像作者并没反对后来这些移民有经济问题，可根据作者的观点这些经济问题又不是由城市移民造成的。不行了绕不清了！NN快帮忙，多谢了！！！

文章细节定位。

easy conclusion --- This assumption has led to the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills.

反过来想，如果rural background person are familiar with urban living and succeeded in cities, 那还能lack of economic mobility in the North 吗

snowflower

right! 醋醋妹妹thank you!

所以说作者驳斥的是lack of economic mobility in the North is tied to rural background，而作者论证的是economic problem不是由于rural background引起的，是这个意思吗？

Arguement: rural background -> black migrant from South suffer from economic problem
Flaw: black migrant from South are urban background
所以weaken了Arguement，说明了economic problem不是rural background引起

顶。

我的理解是，由于rural background 不成立，所以migrant根本不lack the economic mobility。

但其实对做题没影响

This assumption has led to the conclusion that the migrants’subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills.

the easy conclusion tying their subsequent economic problems in the North to their rural background comes into question（产生质疑）

（OG12-138) It has been frequently assumed, but not proved, that the majority of the migrants in what has come to be called the Great Migration came from rural areas and were motivated by two concurrent factors: the collapse of the cotton industry following the boll weevil infestation, which began in 1898, and increased demand in the North for labor following the cessation of European immigration caused by the outbreak of the First World War in 1914.This assumption has led to the conclusion that the migrants’ subsequent lack of economic mobility in the North is tied to rural background, a background that implies unfamiliarity with urban living and a lack of industrial skills.
此处的this assumption就是指的是“it is been frequently assumed ..."，既然这样，为什么A，B等涉及到economic motives的选项不对呢？
