input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: We live in central Phoenix, near the canal . Every day I used to see a homeless old man and his scruffy little dog hanging out down there. I would tell my husband we should give him food for the little dog. It wouldn't have been a problem; we have our own "mini farm" of animals! But he would say "OK!" and then blow the idea off because of our business. Being in Phoenix, Arizona, you can just imagine how hot it gets here, but his winter was really chilly! I had just come from KFC with take-out food for dinner. As I was turning by the canal, the man and his dog were sitting right there all bundled up. Even the doggy had a coat on! Not even thinking about it, I pulled into the parking lot along the canal and piled up a plate of chicken with all the fixings for the man and his little buddy . I gave it to him with a soda and a bottle of water for the little dog. He said, "Thank you, sweetie. You are an angel." And there were tears welling up in his eyes! I told him he was so welcome, and then went home. When my husband dug into the KFC bag he asked, "Were you hungry, or what?" I told him what I did and he said, "Only you!" Then he told me I had done a good thing. A few weeks later, we were walking along the canal and found the man walking to me, with his little dog. He asked whether I would mind adopting the dog. With tears in eyes, he said it had gotten too hard for him to care for the dog. He added that he was planning on heading to Washington State but his dog wouldn't have been up to it, so he hoped to give it to me. "Only you! In this city, you are the only person I can believe in!" Now, every time I watch and pat the dog lying near the fireplace, I will remember the old man's words and wish him good luck. Options: A Because he knew the author was also a dog lover. B Because the author was the person he could trust. C Because the author was the only person he knew. D Because he believed that his dog liked the author. Answer: B Because the author was the person he could trust. Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Have you ever felt annoyed when left talking to yourself after your mobile phone battery runs out in the middle of a call? If yes, then here comes some good news. Scientists are now perfecting a way to recharge electrical equipment while on the move. Researchers from theprefix = st1 /Netherlands,FranceandPortugalannounced last week that they have developed very thin solar panels that can be put on clothes. They can also be added to furniture and rooftops. They change light from the sun into electricity. In about three years, you'll be able to wear a jacket that will recharge your phone as you walk. For camping fans, the development could lead to a tent which charges batteries all day so you can have light or music at night. The basic technology of wearable solar panels is the same as that used for traditional solar panels. Pairs of sheets of semi-conducting silicon are linked together to form the panel. But scientists made them much thinner by using different silicon. At one micrometre, they are of the same thickness as photographic film. "This technology will make it easier for people to use clean energy sources," said a physicist in theNetherlandswho led the team of scientists. But the thin panels are not as efficient as the thicker ones. While some solar panels now operate at an efficiency of about 20 per cent, the new flexible panels are only 7 per cent efficient. But the thinner panel is cheaper. An A4 sized panel put onto the back of a jacket cost less than US$13. It could charge a cellphone during a summer walk in the countryside. As long as you stay within range of the transmitting masts that relay a call to the networks, phones will never again run out of power.
