My first time under time!

For number 4 I chose E over B because B states "Farming practices introduced for the sake of maximizing profits..." but the only thing we know about the farmers are "On our farm, we have great concern for our cows' environmental conditions." Thus, I figured we don't know that they introduced the practices for the sake of maximizing profits or they just did it because they love the cows and wanted them to be comfortable. But, I guess they do state that "thus it would improve profits." so you can infer it's done to maximize profits. I chose E thinking it was a linking one and that A->B->C->D and even though the "key" felt like a stretch I figured it was more aligned then with B. I see how its wrong but damn so tricky!

For my guess assumption I thought: "Assuming tigers will attack people." Since it just states they are aggressive and CAN cause injury to people you're assuming they are going to attack people. If it isn't true and they don't attack people then there isn't an argument. Am I on the right track here?
