标题: prep 2- 62主谓一致是否有问题

67. (28020-!-item-!-188;#058&003766)

A pair of architects in Britain, who say that giant arches, bridges, and walls made of artificial bone could be easier to design and build than conventional structures, and already designed a number of structures, including a bridge, for showing how their idea would work.

(A) build than conventional structures, and already designed a number of structures, including a bridge, for showing

(B) build than conventional structures, and they have already designed a number of structures, which includes a bridge, to show

(D) also to build than conventional structures, already designed a number of structures, including a bridge, which shows

(E) to build than with conventional structures, have already designed a number of structures, including a bridge, which shows

答案是c，我想问的是： A pair of 。。。谓语为什么这里用了have already...，不时应该用has才对吗？

我理解这个句子的结构是： A pair of architects in Britain, who...., have already designed....

难道我的理解有问题吗？请指教。非常感谢！

a pair是复数来的，2个建筑师，前面who say that有提示

那是不是以后看到 A pair of sth，就都用复数的谓语动词那？

我昨天上网找了半天没看到确定的答案。那个NN给个确定的说法。谢谢了！！

这里使用的是逻辑指代，同意carolinelmf所说的，句子中who say that 已经给了提示，表示所指的是两个architests。因为a pair并非名词，而是一个数量词。如果是a cup of sth的话，则用单数。
