Actor William Shatner, who is no stranger to futuristic tech, recently purchased two e-bikes for him and his wife. I've been shopping for an e-bike now for a few weeks, and I've had my eye on the folding electric bike. I've had folding bikes in the past and love the convenience of being able to throw my bike into my car. The e -bike market is ready to go mainstream in the U.S. The price for e-bikes has come down greatly in recent months. At one time, most e-bikes with good components and proper weight were in the $3,000range. Now you can find reasonable quality e-bikes in the $1,000range. With gas prices at all-time highs, e-bikes are an attractive, low-cost option to gas efficient vehicles. E-bike owners are finding that they are great for commuting to work, as traditional bikes can be a problem with office dress and sweat. People who use e-bikes range from commuters to casual cyclers who like a little help with hills and wind,to those who decided to save money on buying a motor bike.These are not for the serious road cycler or professional mountain biker. If you're considering all e--bike, it pays to do some research first.Cheaper e-bikes are going to be heavier and have less battery--power.Higher priced bikes will be made from lighter materials and have better batteries. Another consideration is local motor vehicle laws.For example,according to US federal law,as long as your electric bike is under 750 watts and does not go over 20 MPH then it is a bicycle and not a motor vehicle.Most consumer e--bikes in the $1,000 range don't fit the motorized vehicle description. Question: The writer introduces William Shatner as an example in order to _ . Options: A: show that he is wild about the future technology B: tell us that he is an agent for the e--bike market C: tell us that actors care only convenience no the price D: show that e-bikes are really becoming popular now

Jesse's uncle jumped into the sea and dragged the boy to the store. The boy was not breathing. His aunt gave him mouth-to-mouth resuscitation while his uncle rang the emergency services. Pretty soon, a helicopter arrived and flew the boy to hospital. It was a much quicker journey than the journey by road. Jesse's uncle, Vance Folsenzier, ran back into the sea and found the shark that had attacked his nephew. He picked the shark up and threw it onto the beach. A coastguard shot the fish four times and although this didn't kill it, the shark's jaws relaxed so that they could open them, and reach down onto its stomach, and pull out the boy's arm. At the Baptist hospital in Pensacola, Dr Lan Rogers spent eleven hours reattaching Jesse's arm. "It was a complicated operation," he said, "but we were lucky. If the arm hadn't been recovered in time, we wouldn't have been able to do the operation at all. What I means is that if they hadn't found the shark, well then we wouldn't have had a chance." According to local park ranger Jack Tomosvic, shark attacks are not that common. "Jesse was just unlucky" he says, "Evening is the shark's feeding time. And Jesse was in the area without lifeguards. This would never have happened if he had been in the area where swimming is allowed." When reporters asked Jesse's uncle how he had had the courage to fight a shark , he replied, "I was mad and you do some strange things when you're mad." Question: What was the boy doing when the accident happened? Options: A: Feeding a hungry shark B: Jumping into a rough sea C: Dragging a boy to the shore D: Swimming in a dangerous area
