Working conditions in factories were often horrendous. What, then, drew people into cities to work in these industrial factories?

Money.

Explanation: So many people were immigrating to the Americas with little to nothing and lots were turned away if they didn't look healthy and their entire families would follow. But soo many people were granted access and had no money or jobs, then they would work at factories where they were expendable because they could always get their salary deducted or be replaced with a new immigrant looking for a way to feed their family

the catholic church withhold people's access to the bible during the middle ages.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.
