原题    Increasingly, historians are blaming diseases imported  from the Old World for the staggering disparity between the indigenous population of America in 1492—new estimates of which soar as high as 100 million, or approximately one-sixth of the human race at that time—and  the few million full-blooded Native Americans alive at
  the end of the nineteenth century. There is no doubt that  chronic disease was an important factor in the preciptous decline, and it is highly probable that the greatest
killer was epidemic disease, especially as manifested in virgin-soil epidemics.
        Virgin-soil epidemics are those in which the populations at risk have had no previous contact with the  diseases that strike them and are therefore immunologi cally almost defenseless. That virgin-soil epidemics were  important in American history is strongly indicated by  evidence that a number of dangerous maladies—small pox, measles, malaria, yellow fever, and undoubtedly  several more—were unknown in the pre-Columbian New World. The effects of their sudden introduction  are demonstrated in the early chronicles of America,  which contain reports of horrendous epidemics and steep   population declines, confirmed in many cases by recent   quantitative analyses of Spanish tribute records and other sources. The evidence provided by the documents of British and French colonies is not as definitive   because the conquerors of those areas did not establish  permanent settlements and begin to keep continuous  records until the seventeenth century, by which time theworst epidemics had probably already taken place. Furthermore, the British tended to drive the native  populations away, rather than enslaving them as the   Spaniards did, so that the epidemics of British America    occurred beyond the range of colonists’ direct observation.Even so, the surviving records of North America do  contain references to deadly epidemics among the indige-
   nous population. In 1616-1619 an epidemic, possibly of  bubonic or pneumonic plague, swept coastal New England, killing as many as nine out of ten. During the
   1630’s smallpox, the disease most fatal to the Native  American people, eliminated half the population of the  Huron and Iroquois confederations. In the 1820’s fever
   devastated the people of the Columbia River area,killing eight out of ten of them.
           Unfortunately, the documentation of these and other    epidemics is slight and frequently unreliable, and it is  ecessary to supplement what little we do know with  evidence from recent epidemics among Native Ameri-
(50) cans. For example, in 1952 an outbreak of measles among the Native American inhabitants of Ungava Bay. Quebec, affected 99 percent of the population and killed
   7 percent, even though some had the benefit of modern medicine. Cases such as this demonstrate that evendiseases that are not normally fatal can have devastating
   consequences when they strike an immunologically  defenseless community.
问题：
7. The author mentions the 1952 measles outbreak most probably in order to
  (A) demonstrate the impact of modern medicine on
     epidemic disease
  (B) corroborate the documentary evidence of epidemic
     disease in colonial America
  (C) refute allegations of unreliability made against the
     historical record of colonial America
  (D) advocate new research into the continuing problem  
     of epidemic disease
  (E) challenge assumptions about how the statistical
evidence of epidemics should be interpreted

同问这题解释~！举例之前说的是the documentation of these and other    epidemics is slight and frequently unreliable，为什么后面变成corroborate the document了
