Need History hmk help please?

I have some history questions on the topic of how the roles of women have changed since 1900 (so during the wars).

I have been given a source (its a historians opinion);

Attitudes to women workers remained, in many cases, negative. The ability of women to take on that had been men's work meant that increasing number of males were vulnerable to conscription.

Some women doing skilled work had the full co-operation of male employees. Many other women were restricted to less skilled work and were victims of hostility and even of sabotage.

I have already done what the source suggests, but im struggling on the "knowledge to agree" and "knowledge to disagree". I'm not asking for someone to write it up for me, but I need some ideas, as I have never answered this type of question and my teacher hasn't taught us this topic, and although I have pages of research, im struggling on how to agree and disagree on this type of question.
