The commas must be placed both before and after the nonessential element. For example...
My mom, who hates cooking, ordered takeout.
"who hates cooking" is the nonessential element, and you can see that a comma goes before and after it.
The word assume in this context is used to show how how easily the leader of the animals jumped to conclusions and also how docile the animals who were under his control were. In chapter 3, they also assumed that pigs needed apples and milk to sustain themselves. Assuming things can't always be accurate. It's better to collect facts first before deciding things.
One way of improving one’s diction is through reading. I
believe that when you read, you get to learn a variety of words. When reading
books, make sure that you have a dictionary with you to help you understand
words that are not normally use in casual conversations. Aside from that, you
should also practice using those new words in speaking and writing to help you
gain confidence in speaking or writing the words.
