求大神解答~~~
另："even though" MUST be followed by a clause.
"although", however, can be followed by an adjective or adjective phrase: james, although bigger than many of the other players, is one of the fastest men on the team.

可是A中的Even though不是跟了CP这样的名词短语嘛

把插入语（spear points with longitudinal grooves chipped onto their faces）拿掉，再看句子结构才清楚~

仔细看句子，Even though CP have been found all over North America才是完整的，不要被逗号隔开给迷惑了
