单选题 The government of Pontran claims that Tor City, one of the six major cities in that country, is alone among Pontran's cities in having sustained strong job growth this year. Clearly, however, any job growth there must be purely imaginary; in fact, in Tor City and only there, more people are unemployed this year than were last year.
The argument countering the government's claim depends on the assumption that

A、 unemployed workers in Pontran did not, in significant numbers, move to Tot City when the government claimed Tor City had strong job growth.
B、 the unemployment rate in Tor City is higher year than in any previous year.
C、 actions taken by the government of Pontran significantly affect the unemployment rate in Tor City.
D、 the unemployment rate in Tor City, though increased, is still the lowest of any city in Pontran.
E、 (E) there is no significant seasonal variation in the unemployment rate for Pontran as a whole.

【正确答案】 A

【答案解析】[解析] 本题为假设题型，也是GRE逻辑推理题的重考题。本题推理为：Tor城失业人数多于去年，所以就业增长势头纯粹系虚构。因此，当我们读到(A)，感觉(A)对，就没有往下看的必要。因为(A)排除了失业人数的增加是来自于Tor城之外的可能性，排除了他因，从而可以作为一个很好的假设。
