The earliest Mayanpottery found at Colha,in Belize,is about3,000 years old. Recently, however, 4,500-year-old
stone agriculturalimplements were unearthed at Colha.These implements resemble Mayan stoneimplements
of a much later period, alsofound at Colha. Moreover, the implements' designs are strikingly different from the
designs of stone implementsproduced by other cultures known to haveinhabited the area in prehistorictimes.
Therefore, there were surely Mayan settlements in Colha 4,500 years ago.
Which of the following, if true, most seriouslyweakens the argument?
(A)Ceramic ware is not known tohave been used by theMayan people to make agriculturalimplements.
(B)Carbon-dating of corn pollen in Colhaindicates that agriculture began therearound 4,500 years ago.
(C)Archaeological evidence indicates thatsome of the oldest stoneimplements found at Colha wereused to
cut away vegetation after controlled burning oftrees to open areas ofswampland for cultivation.
(0) Successor cultures at a given site often adopt the style of agricultural implements used by earlier
inhabitants of thesame site.
(E) Many religious and socialinstitutions of the Mayan peoplewho inhabitedColha 3,000 years ago relied on
a highly developed systemof agriculturalsymbols.
论坛上以前的讨论帖都是从 玛雅的石器风格/其他文明的石器风格 角度来讨论的
但从这件4500年前的石器本身来看，它像，且只像玛雅风格（像其他文明的可能性已被原文驳回），如果最后证明它不是玛雅的，又是哪里的呢？
故：这种风格是玛雅独创的。
更进一步：4500已经是既定事实（应该是地质学考证？），存在以下三种情况：
A——玛雅独创：4500年前玛雅存在
B——此文明模仿玛雅：4500年前玛雅存在
C——玛雅模仿此文明：原文已经说了没有任何一种其他文明的石器风格和这个新发现相似，C不成立，回到A和B——4500年前玛雅存在
无论如何都能得出玛雅人早在4500年前就存在的结论。题目无解。
不知道我的逻辑哪里出了问题，求大牛指正！ |
