•types of laws that the government might pass, including steps factory owners should take to improve conditions or steps that the government could do to protect workers and insure better living conditions

The correct answer for this one is this:
"The types of laws that the government might pass, including steps factory owners should take to improve conditions or steps that the government could do to protect workers and insure better living conditions is under the "United States labor law" where it is their responsibility to take care of the employee's rights regarding compensation, salary, pension, income tax, health and safety, etc.

The owners of factories would get local militias to literally kill them or force them back to work
