120. The earliest Mayan pottery foundat Colha,in Belize,is about3,000 years old. Recently, however,4,500-year-old
stone agricultural implements were unearthed atColha. These implements resemble Mayanstone implements
of a much later period, alsofound at Colha. Moreover, theimplements' designs are strikingly different from the
designs of stone implementsproduced by other cultures knownto haveinhabited the area in prehistorictimes.
Therefore, there were surelyMayan settlements in Colha 4,500 years ago.

Which of the following, if true, most seriouslyweakens the argument?

(A)       Ceramic ware is not known to havebeen used by the Mayanpeople to make agricultural implements.
(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 culturesat agiven site often adopt thestyle 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.
A选项为什么不对啊,OG给的解释是The argument does not suggest that the Mayans usedceramics for implements, so this point does
not weaken the argument; it is irrelevant to it.
但A不是说了 Mayan people没有使用 Ceramic ware。

非NN - - 瞎写一下吧 一起探讨
bg：The earliest Mayan pottery foundat Colha,in Belize,is about3,000 years old. 最早的mayan到3000年
promise:Recently, however,4,500-year-old
stone agricultural implements were unearthed atColha. 最近发现个4500年的
hese implements resemble Mayanstone implements
of a much later period, alsofound at Colha.跟之前的长的一样还在同一个地方
additional promise:Moreover, the implements' designs are strikingly different from the designs of stone implementsproduced by other cultures known to have inhabited the area in prehistorictimes.这个东东跟别的地方的不像 主要是排除其他干扰的
conclusion：Therefore, there were surelyMayan settlements in Colha 4,500 years ago. 于是 最早的时间成了4500年

回顾一下逻辑链 为什么能推出这个结论？
本来最早的是3000年 后来发现个4500年的东西 各种方面都像mayan制造的 所以 我推出了 最早的成了4500年

即：像 → 是mayan制造 → 4500是最早的

那么现在削弱结论 我们就要说4500不是最早的 为什么不是最早的?
那么就不是mayan制造的
(0)  Successor culturesat agiven site often adopt thestyle of agricultural implements used by earlier inhabitants of thesame site.
mayan人喜欢模仿前人的制造 那么4500年的东西可能就是前人的

(A)       Ceramic ware is not known to have been used by the Mayan people to make agricultural implements.
那么再看A  这个东西被mayan人用做农业工具。so what? does it mean that the pottery in 4500 is the earlyest one? no . does it weaken the conclusion? no . 所以是无关
我们只需要削弱这个时间上的衔接 至于这个东西用来干嘛 无所谓

单调唱

难道是“ make agricultural implements”和agricultural implements的区别？

显然不是。电脑坏了，用ipad回复的，不方便细讲，你自己好好体会~

is not known to have been used by the Mayan people to make agricultural implements.

玛雅人过去是否使用ceramic 做农产品器具，我们不知道。。这个跟本文讨论没关系。
