※ 引述《maitri (做人呢，最要緊就是開心)》之銘言： : GWD6-40 : It is theoretically possible that bacteria developed on Mars early in its : history and that some were carried to Earth by a meteorite. However, strains : of bacteria from different planets would probably have substantial : differences in protein structure that would persist over time, and no two : bacterial strains on Earth are different enough to have arisen on different : planets. So, even if bacteria did arrive on Earth from Mars, they must have : died out. : The argument is most vulnerable to which of the following criticisms? : A It fails to establish whether bacteria actually developed on Mars. : B It fails to establish how likely it is that Martian bacteria were : transported to Earth. : C It fails to consider whether there were means other than meteorites by : which Martian bacteria could have been carried to Earth. : D It fails to consider whether all bacteria now on Earth could have arisen : from transported Martian bacteria. : E It fails to consider whether there could have been strains of bacteria : that originated on Earth and later died out. : Answer: D : 我想問的是Ｅ。 : 依題目，細菌從火星來－－＞死光了。 : 如果用無因有果解的話，來自地球的細菌（非來自火星，無因）－－＞死光了（有果） : 好像也可以削弱，請問是錯在哪裡？邏輯有一個陷阱就是愛考你「部分」「全部」之間的區別 e選項很明顯就是在說「部分」，「有一些來自地球的細菌絕種了」那其他沒絕種的呢？這些沒絕種的地球本土細菌如果對上題目中的資訊 →跟其他細菌沒顯著差別→所有細菌都是來自同一星球就完全沒有削弱到了。所以請記住「部分」「全部」是邏輯的一個大考點另外一個大考點則是「數量」跟「比例」。 dustin -- No swing, no Jazz. http://blog.pixnet.net/danyuchn73 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 118.166.232.109
