When Pony is coming back from the movies, he realizes he is alone. His first mistake is that he didn't stop to wait for Darry, Sodapop, or one of the gang members to go with him to the movies. This results in him walking home alone, which in turn makes him easy bait. He then gets jumped by the Socs, all because he didn't wait for someone else to go with him.
The answer is Of all the party guests, who was the last to arrive. Hope it helps :)
The act 3 shows that the sequence when Brutus started his act of Betrayal
Esperanza, her sister and her friends were excited to receive shoes from their neighbor in the family of little feet because when they wore the shoes, their legs looked attractive, long and womanly. They proudly walked around the neighborhood in their high-heeled shoes and did not listen when a man from the neighborhood told them that those kind of shoes were not suitable for little girls.
