Read the following article and select the best answer. Article: I have some work in Glasgow today. I was on a really tight schedule, which meant I would have no time for myself all day. I was having one of those days, the train was completely packed out and the conversation going on around me seemed to be particularly meaningless. On top of all that, I had a bit a headache. Walking quickly across the hall, I fished some change from my pocket. There was usually someone at the exit selling The Big Issue(a magazine that helps homeless folk earn a living). As the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue. You had to be homeless to sell the Big Issue. She really looked like she'd been sleeping rough. Her clothes were ragged and she was also rocking from side to side. At first I thought maybe she was trying to keep warm against the biting wind, But she wasn't ,she was moving in time to a tune. I couldn't hear her, but I could see her lips moving. As I got closer, I saw a white cane hanging from her elbow and noticed that she had sunken( ) eyes. She was blind, dirty and living on the streets. I came closer and through the noise of the traffic I heard her sing the immortal line, "--and I think to myself, what a wonderful world!" I bought her last magazine for twice what I'd originally intended. She thanked me, then she picked up her stuff and went tapping off along the pavement--still singing! So, I have my happy memory for the day. And I think it will stay with me a long ,long time. Feel free to borrow it if you like.

Article: In Los Angeles, drivers spend sixty-one hours every year stuck in traffic.These drivers know all too well how bad the traffic can be."There're too many cars, and you can't move around a lot." Professor Cyrus Shahabi also knows about traffic jams.He lives more than 65 kilometers from his office at the University of Southern California, in Los Angeles.He is always late even with the help of a navigation system. He decided to develop a program called ClearPath for that.He says his program uses historical data to predict traffic conditions even before the driver leaves the house. "What's unique is that we use a lot of data that's currently become available including traffic data, weather data, and we analyze that so that we can predict what's going to happen in front of you when you leave home." Professor Shahabi says his system does more than just respond to current traffic conditions.With ClearPath, he says, a driver can decide what time he wants to leave, and ClearPath will give the fastest route.It looks at the entire road network, including surface streets as well as highways, before the driver hits the road.Professor Shahabi hopes to have ClearPath available nationwide and overseas once they can collect traffic data from other cities. "I always thought thatLos Angeles had the worst traffic, but now I know that Shanghai, Beijing, Seoul, Tokyo, believe it or not, Singapore, Hong Kong certainly are examples that can immediately use this." Professor Shahabi hopes to share this new technology with companies that already have navigation systems, such as Google and Apple. Question: What is unique about ClearPath? - It can use a lot of information all over the world. - It can ensure that you will never be late for work. - It helps drivers see clearly what happens on the road. - It helps drivers know the road conditions ahead of time.
It helps drivers know the road conditions ahead of time.

*Question*
Read the following article and select the best answer. Article: Shark on the bait !" shouted Andre Harman, pointing to a spot a few yards behind the outboard motors. His voice gave no indication of panic, but the crew suddenly became tense and fixed their eyes on the water. Slowly, smoothly, Andre drew in the bait.The shark followed. No one asked what kind of shark it was. Everything about it, from its color to its shape, tells that it was a great white shark. Andre lifted the bait aboard. Placing himself between the two motors, he dropped his right hand into the water just as the great head reached the first motor. "My goodness Andre!" I said. His hand seized the big nose, moving it away from the tube of the motor, guiding the shark's head up as it rose out of the water. Andre's hand held the nose, touching it gently. No one spoke. No one breathed. The moment seemed endless. In fact, it lasted less than five seconds before Andre pulled his hand back. Still nobody spoke. Then Andre smiled and said: "The first time was an accident. I was just trying to move the shark away from the motor. Sharks are attracted to motors by their electrical signals and have a habit of biting them to see if they are eatable. " Andre has worked with great white sharks for years. "My hand landed on its nose, and it sort of paused, so I kept it there, and when I did let go, the shark bit and bit as if it was searching for whatever it was that had attracted it." Nearly every encounter we had had with the great whites had been totally illogical. The more we learned, the more we realized how little was really known about them in the past years. Back then, it was generally accepted that great whites ate people by choice. Now we know that almost every attack on a human is an accident in which the shark mistakes a human for its normal food. Back then, we thought that once a great white smelt blood, it would lead to death. Now we know that nearly three-quarters of bite victims survive, perhaps because the shark recognizes that is has made a mistake and doesn't return for a second bite. Question: Most bite victims survive in shark attacks because _ . - they are taught how to fight off sharks - sharks discover they are no threats - they manage to swim to safety - sharks stop attacking them
**Answer**
sharks stop attacking them
