GWD10-15

GWD10-15:

Which of the following most logically completes the argument below?
Although the number of large artificial satellites orbiting the Earth is small compared to
the number of small pieces of debris in orbit, the large satellites interfere more seriously
with telescope observations because of the strong reflections they produce. Because
many of those large satellites have ceased to function, the proposal has recently been
made to eliminate interference from nonfunctioning satellites by exploding them in space.
This proposal, however, is ill conceived, since _______.
A. many nonfunctioning satellites remain in orbit for years
B. for satellites that have ceased to function, repairing them while they are in orbit
would be prohibitively expensive
C. there are no known previous instances of satellites’ having been exploded on
purpose
D. the only way to make telescope observations without any interference from debris
in orbit is to use telescopes launched into extremely high orbits around the Earth
E. a greatly increased number of small particles in Earth’s orbit would result in a
blanket of reflections that would make certain valuable telescope observations
impossible

Answer:E

請問一下,本題DE怎麼選擇,因為我選了很久,選D,錯!

整篇是在講壞掉的人造衛星的處理方式
而不是讓telescope observations 更清晰的方法
所以要找個理由來weaken把人造衛星炸掉是最好的處理方法
再討論...

謝謝!!!^^

一時頭腦卡住!! explode看成explore~~糟糕ㄋㄟ~

AT邏輯,我覺得都很在意最適當選項當中,是否包含了最多原文內容
所提到的因果關係,只要是超出該因果關係之外的談論,都會被剔除.

本題提到了望遠鏡的觀察阻礙是人造衛星的反射,且只提到這一層因果關係.
D選項用了without any,但原本要炸掉已未運作人造衛星的計畫
只是要改善那些衛星造成的reflection(eliminate interference from nonfunctioning satellites),而不是要把所有阻礙都消除(因為有其他阻礙可能是那些小殘骸造成的),所以D選項有些矯枉過正,講到一定要發射一枚哈伯太空望遠鏡才能解決問題. 所以D選項沒提到reflection.
E選項的greatly increased number of small particles,是爆炸後的產物,爆炸後的殘骸產生更大的反射屏幕----->望遠鏡更無法觀察, 提到了文中的因果關係,所以是最adaptable的答案.


題外話,AT考試很讓人欣賞的一點就是藉著考試,第一步篩選未達目的不擇手段的人,選項D是很棒的解決方式,但是可能落入成本激增,打高空.
組織決策要的很多會是最適解決方案,不是最佳解決方案,個人覺得這一題帶有這種意味,能夠在考試中從不擇手段的方向轉為最適化,也算是要進入MBA program的一種訓練吧

哇 上層樓的人兄 好有哲理喔!!!!

小意見,供參考...
D的only口氣太武斷,不是ETS喜歡的答案...
