※ 引述《cindy0416 (ptt)》之銘言:
: Which of the following most logically completes the argument?
: United States manufacturers currently produce most of the world's solar-power
: generators--most of which are exported to Europe.  However, European
: manufacturers are emerging and probably will ultimately capture much of the
: European market.  The United States government is funding initiatives
: intended to encourage use of solar power within the United States.  If these
: initiatives succeed in increasing the demand for solar-power generators in
: the United States, United States manufacturers will probably maintain
: significant production levels, since __________.
: (C) just as European manufacturers enjoy certain competitive advantages in
: Europe, so do United States manufacturers in the United States
: (E) the current market for solar-power generators in the United States is
: very limited



: 答案是C。
: 我的問題是,文中並沒有說到歐洲的廠商有獲得任何競爭優勢或政府補助,
: 說不定歐洲的廠商優勢都跟美國一樣,只是歐洲廠商數增加(供給增加),
: 就可: 就可達到capture European market的效果。這樣的話,C 為何對呢?
                                                                             
你有沒有發覺為何講美國之前出題者要扯歐洲,其實這裡走了一個類比的概念,
就是Euro有什麼條件之後產生什麼結果,USA也有相同條件,也會產生相同結果,
這是走兩者本質相同的類比概念,邏輯正確答案其實都有一些既定的概念,習慣熟悉就好
,盡量不要用合理性的方式來判斷題目,盡量分析出正確答案的模式
                                                                             
: 也就是說,如果今天是美國廠商數在歐洲也增加了,那麼美國也會有高市佔。
: 至於 E,因為文中說 "if ... succeed in increasing the demand",不就代表
: 現在的demand不夠大,市場也因此不夠大嗎?所以我這兩個思量很久就選了E。
                                                                             
if在邏輯概念中叫做assumption,代表在下推論前這個條件已經是成立了,所以現在假設
條件是succeed in increasing the demand,E選項講說market is limited,已經跳脫了
假設條件
