I'm taking a test and have to guess the right answer to the question after the article. Article: Once upon a time, two men were walking in the forest. One was thin and tall, and very bad too. The other was fat and short, and very honest. The tall man said to the short man, "We are good friends. If any beast comes, I'll help you." The short man said, " Of course, we are good friends. We will help each other." At that time, a bear came to them. The tall man climbed up the tree quickly to hide himself in the branches and forgot his promise to the short man. But the fat man couldn't climb the tree. He said to his friend, "Help me! Help me! I can't climb up. Look! The bear is coming!" The tall man said, "No! No! No! You can't stay with me. The tree is not strong." The bear was coming. The short man lay down under the tree, pretending to be dead and holding his breath. The bear smelled around his body. It doesn't touch the dead. After the bear went away without harming the short man, the tall man came down and asked the short man, "What did the bear whisper in your ear when it was close to you?" The short man answered, "the bear told me not to believe such a selfish friend like you. And it also said that a friend in need is a friend indeed." Question: When the bear came, the tall man _ . Options: A: climbed up the tree B: helped the short man C: lay down under the tree D: lost his life
