Re: [CR. ] 請教一題
※ 引述《ortho ()》之銘言：
: Q:
: Worldwide retail sales of home entertainment systems, which include a
: television and an audio system, increased twenty-five percent this year
: over last year. At the same time worldwide retail sales of new automobiles
: declined by about the same percent. These statistics show that consumers
: can no longer afford to purchase both types of products during the same year.
: Which of the following, if true, would cast most serious doubt on the
: conclusion drawn above?
題目:(因)comsumers can't afford two types of products(H&A)→(果) H↑,A↓
問weaken所以要否定原因(果是事實所以無法否定)
: A. Fewer advertisements for new cars appeared on television during the most
: recent year than during the previous year
.→如果是愈來愈少的新車廣告成為他因來否定的話，此選項無說明為何新車廣告會造成新車消費下降
: B. Consumers are spending more money on home entertainment systems than
: on new cars.
→支持argument
: C. People who own home entertainment systems do not drive their automobiles
: as often as other people
→如果有Home entertainment systems的人本來就不常開車，那麼H和A就比較無關了
: D. Prices of home entertainment systems and new cars were higher during
: the most recent year than during the previous year.
→此為無關選項
: E. The reliability of automobiles this year improved significantly over last
year.
→因為人們對汽車的依賴度漸少，所以正好說明(他因)汽車消費比例下降的原因
(E選項比A選項直接weaken)
: 答案是: E (請開燈)
: 請問要怎麼思考?
