What does the simile tells us about the man fear ('like an island of safety in a sea of perils) at that moment
i am really stick on this question

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.

this is the sentence that best shows that fast food restaurants are designed for using unskilled labor.
