Which situation is an example of an external conflict?

a. a teenager tries to get her high school to rehire a favorite teacher.
b. a young boy tries to decide if he wants to play football or the piano.
c. a man feels lonely when his company sends him to a new office.
d. a woman struggles to regain her self- confidence after a divorce.

I think A because it is a external conflict (which is not in the characters mind)

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.

i think the correct answer would be adjustments in life roles.  this causes for one to adjust or change totally his/her career or lifestyle since the present is not beneficial to the life role he is at. for instance, you became a mother you would of course stop going to malls and enjoying life outside. you would be staying at home taking care of your child.
