Answer:
Before slavery became an issue, it is socially acceptable for American people to see that people from a certain race or ethnicity are inferior over the other.
They use that as a justification for all horrible things that they did to these minorities. For example, They enslaved the Black people, heavily overwork Mexican and Asian people on their labor, massacre the native american people to steal their land, etc.
As industrial revolution came into united states, more American people realized that they would no longer need slavery as their labors. They can use machinery to increase their production instead.
This led to a new wave of progressive movement that advocated for the Abolishment of slavery. It opened up people's eyes that they've been using fellow human being as a tool for production and they aware they need to took drastic measure to give them freedom. This eventually led to the civil war which won by the union and force the southern states to gave up slavery.
But the movement didn't stop there. People believe that US faced other social issues that needed to be addressed. So the progressive movement continue to brought attention to problems such as giving women's right to vote, providing legal citizenship for the ex-slaves, Providing workers with minimum wage, etc.

Answer:
Variable interval
Explanation:
In a variable interval, the researcher will not give the reinforcement on a regular schedule.
The purpose of this type of reinforcement is to condition the subjects to adopt a certain behavior even after the reinforcement is taken away in the future.
<u>Example:</u>
Let's say you want to teach your son to put away his toy after he's done playing it.
In order to encourage him, you give him his favorite candy as soon as he's putting away his toy, but you do not give the candy every time he does it. Sometimes you give it, sometimes you don't.
When this happen, your son will start to develop an understanding that there is always a possibility for candy every time he put away his toy.
This will make him more likely to put the toy away and wouldn't sulk even after he does not receive the candy.
