5. Why did many women buy the first sewing machines?
to show they had the latest technology
to do more work at home
to learn to build their own factories
to improve mass production

To show that they had the latest technology.

Explanation:

If we were to answer ' To do more work at home ' I don't think these women want to do more work at home since they have kids. Basically... If you say women, they're married and when you're married, there is a slight chance of having a baby.

To learn to build their own factories also doesn't make sense. Because there is MANY not one so that wouldn't complete my thinking either.

To improve a mass production... That wouldn't get voted by me. AT ALL! Because the mass production, kinda goes off the scale.

But to show the latest technology.. YES! The sewing machines COULD have been the latest technology then. We don't know.

i think this is true
