答案将responds改为respond。

解析 the latter形式上是单数,但因它指代的是复数名词textiles,故谓语动词应使用复数,例如:We distinguish the excellent mall from the common man by saying that the former is the one who makes great demands on himself,and the latter who makes no demands on himself.如果说杰出的人和平凡的人有什么区别,那么可以这么认为,前者对自己提出很高的要求,而后者则对自己毫无要求。Between captain and major,the latter is the higher rank.在上尉与少校之间,后者是军衔较高。
