This won’t be very specific because I am just now learning about the Renaissance, but I’ll try.
The Renaissance art was different from the art that preceded it because the art was more advanced, creative & more improved.
I hope it gave you a boost.
This would be C. 1830- Baltimore and Ohio Railroad :)
Factories? Im not very sure because this is kinda vague. but hopefully you can get it!
Convict lease system, which was popular in the South essentially leased convicts to large agricultural operations. This system led to many forms of abuse of workers who had lost their rights as a result of being convicted of a felony, whether guilty or not. This was particularly true for African Americans in the late-nineteenth century. One of the most notorious of these operations was Parchman Farm in Mississippi, which literally utilized thousands of black convicts for various unpaid tasks.
