input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Scientists recently discovered that pictures on cave walls at Creswell Crags are the oldest known in Great Britain. But they didn't find out in the usual way. Archaeologists often date cave art with a process called radiocarbon dating. The technique can measure the age of carbon found in charcoal drawings or painted pictures. Carbon is an element found in many things, including charcoal and even people. But in this case, there was no paint or charcoal to test. People carved the pictures of animals and figures into the rock using stone tools. The scientists had an "aha!" moment when they noticed small rocks stuck to the top of the drawings. The small rocks must have formed after the drawings were made. "It is rare to be able to scientifically date rock art," said Alistair Pike, an archaeological scientist at Britain's University of Bristol. "We were very fortunate that some of the engravings were covered by stalagmites . When a test proved that the stalagmites formed 12,800 years ago, the scientists knew the art underneath them had to be at least that old. And some of the animals shown, like the European bison, are now extinct--another tip-off that the art is quite old. The artists came to Creswell Crags, This place is one of the farthest points north reached by our ancient ancestors during the Ice Age. At that time, much of the North Sea was dry, so people could move about more easily. Some tools and bones found there are 13,000 to 15,000 years old. They show that the travelers hunted horses, reindeer, and arctic hare. Their artwork is similar to art in France and Germany. It tells scientists that the Creswell Crags artists must have had a close connection to peoples several thousand kilometers away-another important clue to understanding how humans spread out across the world. Options: A The art was carved into stone with stone tools. B The animals carved in the stone are beautiful. C The cave is one of the farthest points in the world. D Some pictures were covered by stalagmites more than 10,000 years old. Answer: D Some pictures were covered by stalagmites more than 10,000 years old. Question:

output: Why do scientists say the art is quite old?

They are likely to make a deadly mistake, causing them to hurt themselves or someone else. Some may think that cellphone are helpful when you need directions or are in an emergency situation. Although I agree, I believe the safest way to use your phone is to pull over to the side of the road first. Some may think that hands-free phones are less dangerous, but studies have shown that the danger remains the same with these. Using a cellphone while driving should be outlawed. One small mistake could change your whole life. Please don't let that happen -- stay off your cellphone while driving.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling together. "Any old papers, lady?" asked one of them. I was busy. I wanted to say "no" until I looked down at their feet. They were wearing thin little sandals, wet with heavy snow. "Come in and I'll make you a cup of hot cocoa." They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread with jam to fight against the cold outside. Then I went back to the kitchen and started again on my household budget. The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, "Lady, are you rich?" I looked at my shabby slipcovers. The girl put her cup back in its saucer carefully and said, "Your cups match your saucers." Her voice was hungry with a need that no amount of food could supply. They left after that, holding their bundles of papers against the wind. They hadn't said "Thank you." They didn't need to. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched. I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job--these matched, too. I moved the chairs back from the fire and cleaned the living room. The muddy prints of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am. Options: A how much money you have had B how you feel about your life C how you have helped others D what job your husband is doing Answer: B how you feel about your life Question:
