The earliest Mayan pottery found at Colha, in Belize, is about 3,000 years old. Recently, however, 4,500-year-old 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?

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.





题干是什么意思?请帮忙看一下,5555我看得眼花

在COLHA发现的最早的MAYAN陶器是大概3000年前的,最近又在COLHA出土了4500年前的石制农具.这些工具和同样在COLHA发现的在时间上晚很多的MAYAN石制工具类似.并且这些农具的设计是和在这个地方的任何史前文化的石制工具的设计是完全不同的.所以MAYAN肯定是在4500年前在COLHA定居下来的
