8 and 1/2 yeah this is the answer
By clearly showing his appreciation, Rick's boss is activating a reaction in Rick's mind. Much like little children when a person is given praise for something they've done correctly then they immediately want to do more things that are right and this causes a chain of reactions; the person will do good or well in the future because they like the praise they are being given and they want more of it. Because his boss is giving praise or appreciation for his work Rick will want to work more and even better because he'll want to get that same praise again at some point, thus Rick becomes a harder worker.
Hope this helped you a little!
Answer:
D: Compare and contrast.
Explanation:
If the task given is asking you to list similarities and differences among American settlers and Native Americans, what you are being asked to do is to compare those groups and evaluate the things they had in common and the things in which they were different. In order to do a good job, you have to read a lot about both groups and compare their actions and believes. By doing that, you will be able to contrast them and notice how they could be similar in some aspects.
