122. Chinese, the most ancient of living writing systems, consists of tens of thousands of ideographic charac­ters, each character miniature(极小) calligraphic(书法艺术) composition inside its own square frame.

(A)  each character a miniature calligraphic compo­sition inside its(同位结构)

(B)  all the characters a miniature calligraphic ;       composition inside their

(C)  all the characters a miniature calligraphic composition inside its

(D)  every character a miniature calligraphic compo­sition inside their

(E)   each character a miniature calligraphic compo­sition inside their

Choice A is best: the appositive terms character and com­position, both singular, agree in number; both also agree with the singular possessive pronoun its. In all the other choices, this three-way agreement in number is violated.

答案没有问题，我自己也同意选择A
