Article: Sixty-five million years ago, an asteroid that crashed on Earth led to the disappearance of the largest animals that have ever walked our planet - the dinosaurs. At least, this is what some scientists believe. But that accident happened so long ago. People have come to believe that we are free of threats from asteroids and everything else from space. However, what happened on Feb 15 , 2013 was a reminder that we're just as _ as the dinosaurs once were. Two objects from space - a meteor and an asteroid called 2012 DA14 - visited Earth's atmosphere on the same day. The former fell in Russia, injuring 1,200 people, while the latter passed by Earth at a record-setting close distance. Scientists had been expecting the asteroid since last year, but the meteor was a surprise. NASA's telescope system only detects asteroids at least 50 meters in diameter , which is just about the size of 2012 DA14. But the meteor was much smaller, which made it harder to spot. But what if we do spot an asteroid that is headed right for Earth? There are several possible ways in which dangerous asteroids could be made to change its orbit. Which method is best depends on several factors and most importantly - how much time we have to stop it. If there is enough time before the hit, we can send off a heavy spacecraft to travel alongside the asteroid. The gravity from the spacecraft would gradually change the rock's orbit. Besides that, scientists could one day use sun-powered lasers to either make asteroids disappear or change their course. If there's not enough time, we'll have to go after the asteroid with a spacecraft and change its orbit with a crash. Finally, if things are truly desperate, there will be only one choice left - to use a nuclear bomb. That could turn the asteroid into a meteor shower, which would be even more dangerous. Question: Which of the following statements is TRUE about the meteor that fell to the Earth in Russia? Yes or no, is the answer "It fell to the Earth and caused great damage to the local community."?
**Answer**
Yes

Article: Katie was in big trouble. She was such a sweet kid; a third-grade teacher always dreamed of having a classroom filled with Katies; she was never ever a discipline problem. I just couldn't imagine why she had made her parents so angry. It seemed that Katie had been running up sizable charges in the lunchroom. Her parents explained that Katie brought a great homemade lunch each day, and there was no reason for her to buy school lunch. They assumed a sit-down with Katie would solve the problem, but failed. So they asked me to help them get to the bottom of this situation. So the next day, I asked Katie to my office. "Why are you charging lunches, Katie? What happened to your homemade lunch?" I asked. "I lose it," she responded. I leaned back in my chair and said, "I don't believe you, Katie. " She didn't care. "Is someone stealing your lunch, Katie?" I took a new track. "No. I just lose it," she said. Well, there was nothing else I could do. The problem was still unsolved the next week when I noticed a boy who was new to the school sitting alone at a lunch table. He always looked sad. I thought I would go and sit with him for a while. As I walked towards him, I noticed the lunch bag on the table. The name on the bag said "Katie". Now I understood and I talked to Katie. It seemed that the new boy never brought a lunch, and he wouldn't go to the lunch line for a free lunch. He had told Katie his secret and asked her not to tell anyone that his parents wanted him to get a free lunch at school. Katie asked me not to tell her parents, but I drove to her house that evening after I was sure that she was in bed. I had never seen parents so proud of their child. Katie didn't care that her parents and teacher were disappointed in her. But she cared about a little boy who was hungry and scared. Katie still buys lunch every day at school. And every day, as she heads out of the door, her mom hands her a delicious homemade lunch. Question: What can we learn from the passage? Yes or no, is the answer "Katie's secret of lunch was discovered by the author by accident."?
**Answer**
No
