Question: Article: President Barack Obama rode a bicycle at the White House Science Fair on April 22. But it wasn't an ordinary bike. As he pedaled, the President stayed in place, while the energy from his pedaling powered a water filtration system. He was testing an invention created by a team of 14 students from Northeast High School, in Oakland Park, Florida. Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project."We were hoping President Obama would ride the bike, but we didn't actually expect him to," Payton told TFK. " It really meant a lot." Kiona agreed. "It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation," she said. The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable , bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. " They can take it to places after natural disasters so that water can be clean for the people there," said Payton. Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to _ students interested in STEM (Science, Technology, Engineering, Maths)."Well, if you're a young person and you produce the best experiment or design, you ought to be recognized for that achievement," Obama said when he first announced the fair. President Obama praised the projects during a speech to attendees after the fair. "The science fair projects of today could become the products and businesses of tomorrow," he said....

Question: Article: Twenty years ago, I drove a taxi for a living. One night I went to pick up a passenger at 2:30 a.m. When I arrived to collect, I found the building was dark exvept for a single light in a ground floor window. I walked to the door and knocked, "Just a minute," answered a weak, elderly voice. After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase. I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car. She kept thanking me for my kindness. "It's nothing," I told her. "I just try to treat my passengers the way I would want my mother treated. " "Oh, you're such a good man." She said. When we got into the taxi, she gave me an address, and then asked, " Could you drive through downtown?" "It's not the shortest way," I answered quickly. " Oh, I'm in no hurry." She said, "I'm on my way to a hospice . I don't have any family left. The doctor says I don't have very long." I quietly reached over and shut off the meter For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had once been a ballroom where she had gone dancing as a girl. Sometimes she'd ask me to slow down in front of a particular building and would sit staring into the darkness, saying nothing. At down, she suddenly said, "I'm tired. Let's go now." We drove in silence to the address she had given me. "How much do I owe you?" She asked. "Nothing." I said. "You have to make a living," she answered. "Oh, there are other passengers," I answered. Almost without thinking, I bent and gave her a hug. She held onto me tightly. Our hug ended with her remark, "You gave an old woman a little moment joy." Question: The taxi driver did not charge the old woman because he _ Yes or no, is the answer "wanted to do her a favor"?
Answer:
No
