182.
The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years old. Recently, however,4,500-year-oold stone agricultural implements were unearthed at colha. These implements resemble Mayan
stone implements of a much later period, also found at Colha. Moreover, the implements’ designs are strikingly
different from the designs of stone implements produced by other cultures known to have inhabited the area in
prehistoric times. Therefore, there were surely Mayan settlements in Colha 4,500 years ago.
Which of the following, if true, most seriously weakens the argument/
(A) Ceramic ware is not known to have been used by the Maya to make agricultural implements.
(B) Carbon dating of corn pollen in Colha indicates that agriculture began there around 4,500 years ago.
(C) Archaeological evidence indicates that some of the oldest stone implements found at Colha were used to cut
away vegetation after controlled burning of trees to open areas of swampland for cultivation.
(D) Successor cultures at a given site often adopt the style of agricultural implements used by earlier inhabitants
of the same site.
(E) Many religious and social institutions of the Mayan people who inhabited Colha 3,000 years ago relied on a
highly developed system of agricultural symbols.

答案D,意思是不是说:4500年前在COLHA居住的人并不是MAYAN,这些人adopt the style of agricultural implements of MAYAN,而事实上真正的吗雅人出现的年代应该在4500年以前?

可是4500年前的时候居住的人adopt的是"used by earlier inhabitants"的东东,那应该是"4500年前"这一时间点之前的某段吧?比如5000年前

我刚刚没说清楚~

好象很有道理哦～！＾＿＾thx～

明白了！谢谢！
