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。
