In an effective compare and contrast paragraph the purpose of the topic sentence is to

go

explanation:

because it can't be a slow, i would say possibly whoa, but there's nothing too surprising about orange juice, and because it tastes awesome it's a go drink, not food.

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.
