The earliest Mayan pottery foundat 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, 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 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 givensite often adopt the styleof agriculturalimplements 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.


这个题目虽然我做对了 但是由D选项反而弄的迷糊了~那如果按照D的逻辑 后继的文明会用先辈们遗留的那些工具什么的  那为什么会出现题目中所说的和在此地生存的其他culture部落用的工具strikingly不同了？
