A sudden increase in the production of elephant ivory artifacts on the Mediterranean coast of North Africa occurred in the tenth century.

原文:十世纪这个地方象牙制品突然产量上升，历史学家认为是因为这个地方发现了象牙并且认为北非和东非从这个时期开始就有一些重要的贸易了
题目：问不能支持的是哪个？
解释：
A说两个地从十世纪就发现了一些金币但是更早的时候没有，那证明两个地方有关系，支持，排除。
B说十世纪钱北非的商人都不会提到东非的一些交易，那增加十世纪后有交易的可能性，支持，排除。
C说东非建筑风格的变化反应了北非的一些风格，两者有关系了，支持，排除。
D说十世纪钱的一些北非的记录显示有东非的动物了，那就不是十世纪才有的了，是在这之前了，不支持，符合题意。
E也是通过船只的风格是两个地方建立了关系，支持，排除

有动物就说明有贸易了吗？动物不能immigration吗？

d是因为专家说象牙增长可能原因有两个，一个可能是因为新地区，另一个可能是因为贸易建交。所以在十世纪之前就有证据说建交的话，就不能说明是建交导致象牙增长。

十世纪前怎么怎么样就说明十世纪后一定就是相反的内容？这个逻辑很可以啊。D说十世纪之前的一些北非的记录显示有东非的动物，你管他什么时候开始有的，现在题目问的是十世纪，只要十世纪有，能建立联系，不就行了么？B，十世纪前北非的商人都不会提到东非的一些交易，十世纪前不交易，十世纪后就会交易了？两个时间段压根半马子关系都没有，写这解析的你上次GMAT没考到800分这次就有可能800了？
