56. Although custom prosthetic bone replacements produced through a new computer-aided design process will
cost more than twice as much as ordinary replacements, custom replacements should still be cost-effective.
Not only will surgery and recovery time be reduced, but custom replacements should last longer, thereby
reducing the need for further hospital stays.
Which of the following must be studied in order to evaluate the argument presented above?
(A) The amount of time a patient spends in surgery versus the amount of time spent recovering from surgery
(B) The amount by which the cost of producing custom replacements has declined with the introduction of the
new technique for producing them
(C)The degree to which the use of custom replacements is likely to reduce the need for repeat surgery when
compared with the use of ordinary replacements
(D) The degree to which custom replacements produced with the new technique are more carefully
manufactured than are ordinary replacements
(E) The amount by which custom replacements produced with the new technique will drop in cost as the
production procedures become standardized and applicable on a larger scale

答案C
這題為何C比B好 哪位大大幫我說明一下

抱歉一下問這麼多題

這是評估衡量題
也就是選一個，可以做為 the indicator that evaluate the argument above.....
原文說，儘管透過電腦輔助設計的義肢比原始義肢 貴 很多，這樣的定作式的義肢 還是相對節省程本

b是說，新科技的介入讓成本降低，若是如此，那題目的argument就有問題了，就不會有貴很多的情況了

C是說，使用電腦設計的義肢，要重複做手術的機率是到什麼程度，要是重複手術的可能性低，就是支持推論，要是可能性高，就是削弱推論，所以選C

多謝 agk大大指點迷津

想請問A為什麼錯呢?

[crazykai]

手術的時間跟術後所需復原的時間比...似乎看不出個所以然哩..@@

我覺得A要對話，應該拿custom replacements 跟 ordinary replacements 的手術時間 或 復原所需時間做比較才合理
