During the 1800s what changed with the factory workforce that resulted in many women going to work as teachers?

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

During the 1800s what changed with the factory workforce that resulted in many women going to work as teachers was that many men started to form Union labors to express themselves and made their voices heard about the many injustices lived in the factories. Workers labored under unhealthy conditions, in areas with poor ventilation, They worked long hours a day and received a low salary with no medical package.

Married women stayed in the house taking care of the children but unmarried women started to study and receive an education. This meant having more job opportunities outside the home than married women. That is why some educated women became schoolteachers at schools while men still trying to get better working conditions at the factories.

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
