Final answer:
Noami Loughnan learned about gender and class inequalities in the munitions factory.
Step-by-step explanation:
Noami Loughnan learned that men were paid more than women for the same work in the munitions factory. She also observed that lower-class women faced gruelling working conditions and low wages in the factory. As for herself, she may have realized the gender and class inequalities present in the workplace and society.
Another possibility is that she discovered a lack of representation and voice for both men and women from lower-class backgrounds in decision-making processes. This could have led her to realize the importance of advocating for better working conditions, fair wages, and equal opportunities for all workers, regardless of gender or social class.
