user: Article: Each Indian tribe had a different language. Many Indians never learned any languages except their own. Do you know how Indians from different tribes talked to each other? They had two ways to talk without sound. One way was by sign language; another way by signals. Sign language is a way of talking by using signs. Indians used sign language when they met strangers. In this way, they could find out whether the stranger was a friend or an enemy. In Indian sign language, signs were made with the hands. One sign meant "man". Another meant "horse". To tell the time of day when something happened, an Indian pointed to the sky. He showed where the sun had been at the time. Indians usually used signals when they wanted to send messages to someone far away. To make signals, an Indian might use a pony. He might use a blanket. Or he might use smoke, a mirror or fire arrows. To signal that he had seen many animals, an Indian rode his pony in a large circle. Sometimes the Indian gave a signal like this and then went away to hide. This meant that there was danger. The blanket signal was visible from far away. An Indian held the corners of a blanket in his hands. Then he began to swing the blanket from side to side in front of him. An Indian could send many different signals with his blanket. He could also send many signals with a mirror. He usually used the mirror to warn someone of danger. Of course, mirrors could be used only when the sun was shining. At night, Indians used fire arrows for signaling. Now you can see that Indians didn't need to learn each other's language. They could talk to one another by using signals or sign language. Question: The story tells about  _  . Yes or no, is the answer "how Indians communicate between different tribes"?
No

Question: Article: Cleverness is a gift while kindness is a choice. Gifts are easy---they're given after all. Choice can be hard. I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2300 percent per year. I'd never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me, I had just turned 30 years old , and I'd been married for a year, I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't , and I wasn't sure what to expect, MacKenzie told me I should go for it. As a young boy, I'd been a garage inventor, I'd always wanted to be an inventor, and she wanted me to follow my passion. I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, "That sounds like a really good idea, but it would be an even better idea for someone who didn't already have a good job." That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but ultimately, I decided I had to give it a shot. I didn't think I'd regret trying and failing. _  After much consideration, I took the less safe path to follow my passion, and I'm proud of that choice, For all of us, in the end, we are our choice. Question: We can know from the passage that   _  . Yes or no, is the answer "the author might not regret if he failed the idea"?
