OG-67

[dibert8]

用概念解題比較容易選到答案,用實際數字可能每個選項都不是答案.
(A) 數字 vs 比例
(B) 另有他因
(C) 本身弱化
(D) 本身弱化
(E) 成立,可能 strengthen 命題 (i.e.為命題找到理由).

答案是E。對E選項有疑問,我覺得E選項也可以WEAKEN
S的平均價錢比較低,所以T的居民跑來S買,才造成了S的銷量大於T
因此,並不能達成結論S是better informed
而解答的意思是說E可以解釋S.T銷售差異但沒有WEAKEN
難道是我想太多?做了額外的推論?
請指教,謝謝！

這題重新思考了一次:為什麼 (A) ~ (D) 可以弱化,而 (E) 不行? (E) 如果是在 (A) ~ (D) 任何一個情形,不就弱化了嗎? 差別在於 (A) ~ (D) 直接弱化結論,而 (E) 沒有,選項裡沒有給的情形,不能自己假設. (E) 對於結論沒有作用.

OG 解釋: Choice B suggests that many newspapers sold in S inform citizens of T, not S. Choices A and C both show how greater newspaper sales can occur without the average citizen having greater familiarity with the news. Finally, choice D suggests that much newspaper reading in S is not a source of information about world events. The price differential noted in E might help to explain the difference in sales, but it does not undermine the conclusion based on that difference. Therefore, E is the best answer.
