This is for quant section: I have been facing an issue. In a test of duration 1 hour I seem to attempt only 5 to 6 questions in the first 20 to 30 minutes and race up to a total of 20-25 questions in the remaining time. This has been happening for a long time. The accuracy does not take a hit but it seems like a bad thing not to address this issue. If anyone has anything to share, please do.

RC:


In August 1348 the bubonic plague, or Black Death, suddenly appeared

in England. Its germs were carried by the fleas on black rats that came

into the country on ships from abroad. The first outbreak of the plague

was of intense ferocity, for the people had no immunity and persons

living close to the margin of subsistence fell victims to the disease.

Returning in 1361, the plague caused high mortality among children

born since 1348; there were other visitations in 1368 and 1375. High

farming in the thirteenth century had been based on the scarcity of

land, a large population, and a great demand for food—conditions that

had forced the peasants to remain on their holdings and to accept the

burdens of serfdom. But when the demand for food was less, the profits

of agriculture shrank. High farming, which had already been slipping

before 1348, came to an end.

The startling fact about those figures is the amazing drop in

population between 1348 and 1377. It may be the number of people in

overcrowded England already was beginning to decline before the

coming of the Black Death. There were floods and famines in the years

between 1315 and 1317. Certainly the plague caused a high mortality.

In some monasteries the monks all but disappeared (it is thought that

half the clergy in England fell victims to the pestilence). The Black Death

had its most striking effect on the rural economy. The balance between

the number of labourers and the amount of land under cultivation and

the relations between lord and peasant were quickly altered. There were

deserted villages and many unoccupied peasant holdings. After the first

visitation widows and widowers remarried quickly and produced as

many children as before; but because of the high mortality among

young people this population increase was not maintained later in the

century.

The work of the manor could not be performed by the villeins who

had survived the plague; the lord had to employ casual labor at wages

that doubled within a decade. Moreover, a villein, once tied to his

holding by economic necessity, could easily run away to another manor

where employment would be offered to him with no questions asked.

Landowners complained bitterly of the labour shortage and of the

wages they had to pay. In 1351 they obtained the Statute of Laborers,

which fixed wages at the rates before the plague, declared that all

landless men must accept work when it was offered to them, and

prohibited peasants from moving from one manor to another. For a time

the statute had some effect, but in the long run it was useless, for

wages continued to rise and employers had to pay them. There was also

a scarcity of tenants. Few manors were without vacant holdings; hence

the yield was less and income from the land declined. Agricultural

products no longer fetched high prices. Yet the cost of luxuries and of

manufactured goods was rising.

Thereafter the plague subsided in the rural areas but remained endemic

in London and other towns, where it could become active at any time 

and could spread along lines of communication into the country. It

remained in England for more than 300 years.


Ques.:- 

Which of the following claims would, if true, most substantially weaken the

author‘s claim that the plague brought an end to the practice of high

farming?

A. The practice of high farming was reinforced after the floods and

famines in the 1310s reduced the amount of arable land.

B. Immediately following the plague, the profits of agriculture would see

a rebound due to the stabilization in wages and food prices.

C. The numbers of peasants working on English farms decreased

throughout much of the years of plague.

D. The Statute of Laborers began to be strictly enforced when it became

apparent that wages were still rising.

E. Over the next few years following the plague, the incomes of

agriculturists kept falling lower and lower.
