Most novelists and historians writing in the early to mid-twentieth century who considered women in the West, when they considered women at all, fell under Tuiner's spell.
这句话是杨鹏长难句阅读上的，我想问下这句话的语法在GMAT考试中算错的么？如果不算的话那第一个逗号前面的名词为什么可以单独存在？我语法不好啊，请大家耐心解释下，不胜感激~

when they considered women at all, 这句是插入语吧。
Most novelists and historians fell under Tuiner's spell.这个是主谓
