15 Chinese, the most ancient of living writing systems, consists of tens of thousands of ideographic characters, each character a miniature calligraphic composition inside its own square frame.
The answer is A, and the question is about "agreement", while I'm not clear with the structure of the sentence. 我觉得划线中的“each character “ 中的character 应该是个动词吧,那样的话不是应该用characters以达到主谓一致吗?非常confuse啊,期待nn给解答一下我的傻问题,脸红退下~~
