Read the excerpt from Jungle Book: Mowgli's Brothers. There were yells of "Silence, thou man's cub!" "Let him speak. He has kept our law!"; and at last the seniors of the Pack thundered: "Let the Dead Wolf speak!" When a leader of the Pack has missed his kill, he is called the Dead Wolf as long as he lives, which is not long, as a rule.

Akela raised his old head wearily: –

"Free People, and ye too, jackals of Shere Khan, for twelve seasons I have led ye to and from the kill, and in all that time not one has been trapped or maimed. Now I have missed my kill. Ye know how that plot was made. Ye know how ye brought me up to an untried buck to make my weakness known. It was cleverly done. Your right is to kill me here on the Council Rock now. Therefore I ask, who comes to make an end of the Lone Wolf? For it is my right, by the Law of the Jungle, that ye come one by one."

This excerpt best supports which theme?

Youth is more important than wisdom.
Leadership is hard and lonely work.
Silence has greater power than words.
Nature is a place of peace and calm.
