Difficult To Understand

Overall, all of the reasonings seemed easy to understand but if I had to pick the most difficult out of the list, I would choose reasoning by criteria. I found this reasoning to be the most difficult to understand, even though I just established that all of them seemed easy to understand, because the link on the professor's website was a little vague. I only understood it after I read examples from the link given. I guess I found it more difficult to understand out of the list because its title seemed the most vague. Everything else seemed straightforward. By establishing legitimate reasoning through criteria, it will help to make logical decisions based on this criteria. It is something that I had to read a couple of times in order to properly understand it but other than this one type of reasoning, everything else seemed straightforward and easy to comprehend.
