What problems does he suggest merry-go-rounds and carousels present in a segregated society?

Times are changing and people often are not able to go with the flow - but on the MGR, there is a certain flow to the movement. There are no black and white seats (horses) to choose from on the MGR. There are plenty of horses for everyone to have a turn. You might even get to sit next to someone new!

Explanation:

There is no front or back to the MGR. It is a continuous circle moving and has no segregation to do with it at all. Maybe the problems would arise out of people not being able to make a choice of where to sit out of fear or out of prior knowledge of everyone not being invited. Now, the playing field is even. A horse for each person. No front. No backseat. Anyone can live free on the MGR.

the answer:

in the first part of the story running is all that matters to squeaky. running gives her confidence and defines who she is. at the beginning of the story she says that other kids call her mercury because she runs very fast. in the text she refers to herself as "miss quicksilver".

the line that provides the best evidence that squeaky has self-confidence is

" and i continue with my breathing exercise, strolling down broadway toward the ice cream man on 145th with not a care in the world cause i am miss quicksilver herself".
