The U.S. census is not perfect: thousands of Americans probably go uncounted. (Concession)
However, the basic statistical portrait of the nation painted by the census is accurate. (Main Conclusion)
Certainly some of the poor go uncounted, particularly the homeless; (Evidence)
but some of the rich go uncounted as well, because they are often abroad or traveling between one residence and another. (Evidence)
个人意见, 试试看:
由于argument抱持的结论是 the basic statistical portrait of the nation is accurate.
而两个Evidence又只是针对Uncounted poor and rich American.
所以(B)就算不成立, 即All Americans may not reasonably be classified as either poor or rich.
也不会使得 the basic statistical portrait of the nation is not accurate.
同样的也有(A)(E)
再说说Mindfree的链条式逻辑, (B)与上面的Evidence连不上关系....(all Americans & uncounted Americans)
接着看(C)(D):
(D)讲的是数量上homeless与rich Americans的相等, 但这个错误类比(homeless与rich)显然不对,
变成uncounted poor等同于所有的rich Americans, 不合一般统计的计算; 就算不牵扯统计, 这样数量上的相等也不能说明the basic statistical portrait of the nation is accurate.
(C)讲的是两个uncounted的比例一样, 讲讲统计, 由于母体偏大(所有美国人), 而uncounted的比例只有thousands of Americans probably go uncounted, 因此在uncounted比例一样的前提下, 并不影响其poor与rich的比例, 也就是说the basic statistical portrait of the nation is accurate.
