求助36套中的一句话

seeker2013UID: 3179096

Fundamentally, however, the conditions under which women work have changed little since before the Industrial Revolution: the segregation of occupations by gender, lower pay for women as a group, jobs that require relatively low levels of skill and offer women little opportunity for advancement all persist, while women's household labor remains demanding.

整个句子的主干是什么？ the conditions all persist? under which 到 Revolution 是不是 是condition的定语从句？
