Answer:
Since most of the men in the city had to join the armed forces during the war, women had to take on their work outside the home.
Step-by-step explanation:
During the war, most men had to quit their jobs and join the armed forces to fight for the defense of the country. However, the country's economy could not stand still, as military expenditures were very high and the families of these men needed to be supported. For this reason, women had to take on jobs outside the home in branches that were marjoritly masculine. This was the main reason for the increase in the female workforce.
