謝謝樓主的貼..我從中獲益良多
想問一下樓主給的十道題是不是都是找出necessary assumption?而不是sufficient assumption?

hi sdcar2010 , could you giv us a sufficient question and its analysis? I see most examples are necessary ones.

My answer is B.  For it fills in the gap between the premis and the conclusion.

My 28 questions are hard questions. If it only took you one hour to finish, you are one of the best.

有十道題的第五題...
樓主給的答案C是NECESSARY ASSUMPTION嗎..
我看了樓主的答案還是不明白..感覺C不是必要條件
因為就算C不對..好像總結也沒有影響

I learn a lot from sdcar2010's post. I think sufficient assumption is more or less similar to strengthen, but I'm not sure...
