US Blacks Hard-hit by Cancer

Death rates for cancer are falling for all Americans,but black Americans are still more likely to die of
cancer than whites,the American Cancer Society said Monday.
In a special report on cancer and blacks, the organization said blacks are usually diagnosed with cancer
later than whites,and they are more likely to die of the disease.
This could be because of unequal access to medical care,because blacks are more likely to have other
diseases like diabetes as well,and perhaps because of differences in the biology of the cancer itself,the report added.
"In general,African Americans have］ess likelihood of surviving five years after diagnosis than whites for
all cancer sites and all stages of diagnosis,"the report said.
"In describing cancer statistics for African Americans,this report recognizes that socioeconomic dispari-
ties and unequal access to medical care may underlie many of the differences associated with race."
The Cancer Society said blacks should be encouraged to get check-ups earlier,when cancer is more
treatable,and it said more research was needed to see if biological differences play a role.
选项 Public policy and education efforts may help to do away with________.
A:death rates       
B:various cancers
C:unfair social differences       
D:biological differences
答案C
解析由文章第一段的内容可知，美国黑人的死亡率高于美国的白人。该段只是将美国黑人与美国白人的癌症死亡率进行了比较。故选B。
前三项原因在文章第三段中都被提到了，而早期诊断是有助于降低癌症死亡率的。
利用题干中“检测”作为线索，由文章第六段的内容可以得知，癌症越早发现越有利于治疗。
文章第七段提到，公共政策和教育有助于消除不平等的社会差异。
利用题干中的时间作线索，由文章的倒数第三段的内容可知，从1992年以来，美国黑人的癌症死亡率下降了。
