I'm taking a test and have to guess the right answer to the question after the article. Article: "Particulate Matter 2.5(PM2.5 for short)"is now ,it seems, officially an enemy of the people.The harmful,tiny pieces of matter,up to 2.5 microns in diameter, are too small to be seen by the naked eye.So they can be easily breathed into the lungs of people and do harm to people's health.With the issue of pollution so heatedly discussed,some people are wondering what possible solutions might be on the way. _ might very well be a renewed effort to kick-start the electric car industry.Some reports suggest that the use of bakery cars should be expanded from the present five cities to 20 more. But so far no country in the world has succeeded in making the dream of emission.free driving a reality.Despite the lofty ideal,the electric car has so far been a disappointment, accounting for only a fraction of l%of global car sales.And the same is true in China.There is an existing target to put five million on the road by 2020 but the Chinese consumer is so far very much unconvinced. BYD Auto Company in the southern city of Shenzhen is just one electric vehicle maker hoping that the time is now ripe for the government to step up its efforts.BYD is making electric cars but as yet not selling in great numbers.Electric cars are not cheap.It would still leave more than$40,000 to be paid before you could drive away in a BYD e6.And buyers have worries other than price. "I think that when you talk to a regular Joe about electric vehicles he is excited, but when you ask Mr. Joe to buy one,he's nervous,"said Isbrand Ho from BYD's Auto Export Trade Division."We call that 'range anxiety'.How far will my vehicle go?" The answer for an e6 is well in excess of 300 kms(190 miles)on one charge.That is the sort of number that might just start looking attractive to less price-sensitive customers but China still doesn't have anything like enough charging stations to make the car a practical choice. Last year, BYD sold only l,700 electric cars in China.Isbrand Ho tells me that at that volume the car is naturally expensive,due... Question: According to Isbrand Ho, will bring down the price of the electric cars. Options: A: improvement of environment B: innovation C: new technology D: more production

I'm taking a test and have to guess the right answer to the question after the article. Article: Our daughter Kerrin, a student at Boston University, had been home for a week-end visit, and I dropped her off at the bus station just in time for her back to college. After Kerrin's bus had gone and I was driving away, I noticed that she had left her purse on the passenger seat. Worried that she would arrive in Boston without money or keys to her room, I called my wife, Bette Jean, on the car phone, explaining why I would be late. As I was following the bus, Bette Jean phoned me back to say she had phoned the bus dispatcher on the other line and he, in return, had phoned the bus driver on yet another phone. The driver asked me to wave out of my window to show where I was. Then he pulled over at a rest stop, and I did the same. Kerrin jumped off the bus, and I handed her the purse and went on my way. Question: Which of the following is not true? Options: A: The bus was too fast for the car to catch up with in no time. B: The writer had tried to phone the dispatcher but failed. C: The writer couldn't get in touch with the driver by the phone. D: Both the writer and the bus driver could use the car phone.

I'm taking a test and have to guess the right answer to the question after the article. Article: When I was ten my dad helped me buy my first ten-speed bicycle from Allen. I put up $60 of my grass cutting and snow shoveling money and my dad put up the other half I would pay him back over the next six months. Although it was not in the latest style, it was my ticket to the adult world. I spent that summer and autumn riding happily. My sister Liz, a prisoner of her five-speed bicycle, never had a chance to keep up. Just before the Christmas deadline to pay my dad back, we were hit with several snowstorms. This allowed me to shovel enough driveways to pay off my debt. I was now officially a bike owner; it was a feeling unlike any other. On that Christmas morning, my dad gave me a used portable record player. I was excited. However, my joy was short-lived after my dad called my sister to the kitchen. "We have one more gift for you." he said as he opened the door that led to the garage. There, on the steps, stood a new ten-speed bicycle. "It's not fair," I complained. "I worked so hard for my bike and it's not even new. Then Liz gets a new bike. She didn't have to do anything for it. " My dad smiled. "She didn't have to do anything for it because it' s not really for her," he said. What did that mean? I didn't want her bike. By spring Liz and I were riding all over town together now that she could keep up. As we grew, Liz and I became true friends. Still I wasn't smart enough to figure out what my dad meant until years later. That new bike was not a gift for Liz -- it was a gift for me. He'd given me the gift of my sister's company, the ability to stay together rather than drift apart in the face of my ability to travel. He gave me my best friend. Question: What do we know about the author's bike? Options: A: It was worth $120. B: Allen bought it for him. C: It was very fashionable. D: He didn't like it actually.
