First question////
Actually, Candy is angry at Curley's wife after her death. Her death has ruined his dream...... because of her actions, Lennie did what he did...... and Candy knows the dream is dead, there will be no farm.
Entire floor if your looking for the exact answer.
He lied to him because he knew that the Cyclops would call his brothers, when blinded, so he said his name was "nobody" so as to have the Cyclops yell out: "Nobody has blinded me". This in turn caused his brothers to not react at all, because they thought that gods had blinded his brother, therefore he is yelling that Nobody blinded him. Let's say then that the third sentence is the only one that can fit the story.
