An agreement was made in June when both sides met for the first time in 21 years by anot

问题补充：

An agreement was made in June when both sides met for the first time in 21 years, by another meeting for further cooperation.

A. following

B. to follow

C. having followed

D. followed

答案：

A. following

B. to follow

C. having followed

(答案→)D. followed

解析：考察分词做状语。本句中的动词follow与主句的主语an agreement之间构成被动的关系，故使用过去分词在句中作状语。句意：在双方以后的第一次会面中双方达成了协议，接下来的是进一步合作的另外一个会面。故D正确。
