Before 1850, workers in american mines, mills, and factories were poorly paid, but their safety on the job was always protected by strict laws.
a.
true
b.
false

The answer is false because laws enforcing workplace safety did not show up until 1970. 

This is clearly false. Those workers were working where there was a high risk of danger. In the mines, it would get so heavy and dense that it actually made it kind of hard to breathe. Many workers got sick, and I can see why. After so long of working in these very harsh conditions, and after breathing all of the dirty air, it can take a toll on your lungs and such. These workers were at high risk of endangerment, and sometimes it was even fatal.

I'm taking that test i will let you know!
