Question

look at the poster. the westinghouse electric and manufacturing company produced this poster during world war ii in order to educate the public about different jobs available to women. illustrate that women were strong enough to join the military. promote the idea that working was a woman’s patriotic duty. show support for women while their husbands were at war.

Explanation:

The "We Can Do It!" poster by Westinghouse during WWII aimed to encourage women to work in factories and industries to support the war effort, framing it as a patriotic duty. The first option is incorrect as it's not about educating on job types. The second is wrong as it's about factory/work, not military. The fourth is not the main purpose; the focus was on getting women to work for the war, so the third option fits.

Answer:

promote the idea that working was a woman’s patriotic duty.
