I believe the answer is: Primary
For example, let's say take a look at normal employees at a company.
For most of them, the main reason they spend their time to do the job correctly is to obtain money/salary even though they have to spend their time being scolded by unlikable boss.
In the scenario above, we can say that money is the primary reinforcer for the target behavior
Structure body and conclusion
<span>Industrial revolution affected the north a great deal and was all pretty much positive except for the problems that came when immigrants started coming in but the immigrants made the population in the north skyrocket. The economy was doing well, the transportation system was going good. The only problems were the labor unions that formed when the workers decided they wanted more pay and better working conditions and the wealthy wanted to increase profits in their businesses. In the South there were many struggles when it came to segregation and discrimination against african americans. The economy was being rebuilt after it wasnearly destroyed during the civil war and the railways were also. The population was low and it didnt seem like a great place to be during this period. In the midwest there were also labor unions like in the north but they like the north also had many positive things come out of the revolution like there transportation system and their rapid population growth because of immigrants. In the West their transportaion was great with the transcontinental railroad and there economy base was agriculture but they had problems when immigrats from China came in and offered to work for less wages, this threatened everyone elses jobs. If i had to choose a region to live in during this time it would either be the North or Midwest because their economy was booming, the cities were expanding, the population was growing like crazy and it seems like the best places to have been in during that time.</span>
