: GWD6-Q14:
: Political Advertisement:
: Mayor Delmont’s critics complain about the jobs that were lost in the city
: under Delmont’s leadership. Yet the fact is that not only were more jobs
: created than were eliminated, but the average pay for these new jobs has been
: higher than the average pay for jobs citywide every year since Delmont took
: office. So there can be no question that throughout Delmont’s tenure the
: average paycheck in this city has been getting steadily bigger.
: Which of the following, if true, most strengthens the argument in the
: advertisement?
argument: average pay (new jobs) > average pay (citywide every year)
--> average paycheck in this city has been getting steadily bigger.
argument 是在比較新工作以及一般平均工資水準的差距
而得到平均工資持續上升 所以重點在於這樣的因果關係是否可以成立
: A. The average pay for jobs created in the city during the past three
: years was higher than the average pay for jobs created in the city earlier in
: Mayor Delmont’s tenure.
這是 CR 常會犯的錯誤毛病 就是在已經確定的事實做更細部的推論
譬如我說 A 班平均比 B 班平均身高還要高
則 A 班的身高分布就相對不重要
而此題已經確定新工作比一般平均工資還高
所以新工作的工資如何分布就相對不重要
我合理猜想 妳可能會推論到由於新工資持續上升
所以將來薪水有可能穩定上升 有加強作用
但要看清楚結論 說的是 "has been getting steadily bigger"
討論的是過去發生的推論結果
: B. Average pay in the city was at a ten-year low when Mayor Delmont took
: office.
: C. Some of the jobs created in the city during Mayor Delmont’s tenure
: have in the meantime been eliminated again.
: D. The average pay for jobs eliminated in the city during Mayor Delmont’s
: tenure has been roughly equal every year to the average pay for jobs citywide.
當妳在和一般平均做比較時 並不會把流失的平均工作薪資算入
但如果流失的平均工作薪資 都比新工作的平均薪資來的大
那就會 weaken 妳的結論 因為流失的平均薪資比新加入的平均薪資大
那總和平均就會縮小 這推論就會出現問題
: E. The average pay for jobs in the city is currently higher than it is for
: jobs in the suburbs surrounding the city.
: 請問一下 這題 就是要支持結論:在D的任期平均薪資提高
: 我對A & 正解D答案比較有點疑問
: A說就說再過去3年平均薪資高過於再D執政的薪資
: 請問這題哪裡錯? 比過去高不就直接支持結論了
: 正解D 當初看了 就當作補充背景條件刪除了
: 請問該怎麼想
: 謝
變體題給妳做參考，答案 (C) (Support --> Weaken):
Political Advertisement:
Mayor Delmont’s critics complain about the jobs that were lost in the city
under Delmont’s leadership. Yet the fact is that not only were more jobs created than were
eliminated, but each year since Delmont took office the average pay for the new jobs created
has been higher than that year’s average pay for jobs citywide. So it stands to reason that
throughout Delmont’s tenure the average paycheck in this city has been getting steadily
bigger.
Which of the following, if true, most seriously weakens the argument in the
advertisement?
(A) The unemployment rate in the city is higher today than it was when Mayor
Delmont took office.
(B) The average pay for jobs in the city was at a ten-year low when Mayor
Delmont took office.
(C) Each year during Mayor Delmont’s tenure, the average pay for jobs that
were eliminated has been higher than the average pay for jobs citywide.
(D) Most of the jobs eliminated during Mayor Delmont’s tenure were in
declining industries.
(E) The average pay for jobs in the city is currently lower than it is for
jobs in the suburbs surrounding the city.
