58. Neither a rising standard of living nor balanced trade, by itself, establishes a country’s

ability to compete in the international marketplace. Both are required simultaneously since

standards of living can rise because of growing trade deficits and trade can be balanced by

means of a decline in a country’s standard of living.

If the facts stated in the passage above are true, a proper test of a country’s ability to be

competitive is its ability to

(A) balance its trade while its standard of living rises

(B) balance its trade while its standard of living falls

(C) increase trade deficits while its standard of living rises

(D) decrease trade deficits while its standard of living falls

(E) keep its standard of living constant while trade deficits rise.

这题的答案为A,请问C为何错，OG上的解释看不太懂。

29. The number of people diagnosed as having a certain intestinal disease has dropped

significantly in a rural county this year, as compared to last year. Health officials attribute this

decrease entirely to improved sanitary conditions at water-treatment plants, which made for

cleaner water this year and thus reduced the incidence of the disease.

Which of the following, if true, would most seriously weaken the health officials’ explanation for

the lower incidence of the disease?

A. Many new water-treatment plants have been built in the last five years in the rural county.

B. Bottled spring water has not been consumed in significantly different quantities by people

diagnosed as having the intestinal disease, as compared to people who did not contract

the disease.

C. Because of a new diagnostic technique, many people who until this year would have been

diagnosed as having the intestinal disease are now correctly diagnosed as suffering from

intestinal ulcers.

D. Because of medical advances this year, far fewer people who contract the intestinal

disease will develop severe cases of the disease.

E. The water in the rural county was brought up to the sanitary standards of the water in

neighboring counties ten years ago.

这题的答案为C,请问为何选它？

58.贸易赤字增加是生活水平提高的原因，C中说的是当生活水平提高的时候还增加贸易赤字，那只能使贸易失去平衡，从第一句话可以知道没有竞争力，所以不能选C。

29.他因削弱。查出得那种肠道疾病减少的原因是之前误诊造成的，现在查出来之前断定为那种肠道疾病的其实是肠溃疡。

建议去看看OG讨论汇总贴，在置顶文章里，里面有lawyer_1和携隐等大牛的精辟解释。
