Women working outside the home during the roaring twenties could expect: to make more money than men in the same position to work longer hours than their male counterparts to be forced to stay at home if they became pregnant to make less money than their male counterparts

Hello, So  I am assuming this is a multiple choice question..
Your answer would be 

Make less money than there male counter parts, , women were most expected to make less money then men...

Reason being... is that they were looked down upon and many men thought it was shameful that a women made a higher income or got a higher wage than a man.
 Reason why the rest of the choices are wrong...

When some women got pregnant , they could not stay home (some of them depending on the boss) because they needed the money to support there families.
Women never made made more money then men back in the day,it was shameful to the man and the man felt like a failure , so women would get paid less.
Also, not all of the women back in the day (soaring 20's) got hired for a job because of gender discrimination, not to mention that they had kids and families they had to look after, so it was impossible for a lady in the time to work for  longer hours.
