Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Construction workers in Southern California have made a wild discovery. They were digging at a building site in San Timoteo Canyon when they unearthed hundreds of ancient animal fossils. Researchers say the bones hold important clues about the history of the region. Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well. "This is a huge find," says Rick Greenwood, a scientist studying the site. "I don't think most people had any idea that those types of animals were wandering around here more than a million years ago." San Timoteo Canyon is located about 85 miles from Los Angeles. The area of the canyon where the fossils were found was once part of a green river valley. Today, the region is dry and plant life is rare. Most of the fossils are well preserved. Experts say a muddy lake bed may have trapped thirty animals that wandered over for a drink. The mud helped to protect the animal fossils. The remains are a million years older than those discovered at the famous La Brea Tar Pits in Los Angeles. Scientists studying the bones will be able to learn more about how the animals adapted to changes in the environment. "We have a confused view of what this time period was like, " says another scientist. "A discovery like this could really be an important contribution." About 35 different animal species are represented in the fossil collection. Scientists began removing bones from the site last fall. The project was completed this summer. Starting next year, the fossils will be on display at the Western Science Center in the nearby city of Hemet, California. Options: A fossils were discovered in the canyon for the first time. B the canyon in ancient times was quite different. C more research work will be carried on in the canyon. D the river water helped to protect the animal fossils. Answer: C more research work will be carried on in the canyon. Question:
A: From what Rick says, we know _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The Man behind Blue Jeans Levi Strauss was born in 1829 in Bavaria,Germany. He was the fifth of six children. His father sold dry goods from door to door. (Dry goods include many different things; fabric , thread,scissors,combs,buttons,yarn,etc.) In 1845, his father died. All six children decided to go to the United States. Two of Strauss' bothers started a dry goods company in New York City. Strauss' sister Fanny and her husband started a similar business in San Francisco. Strauss decided to go to the southeastern part of the United States. For eight years, he walked along the country roads selling dry goods from door to door - just like his father in Bavaria. In 1853, Strauss decided to move to San Francisco.(At that time, thousands of people traveled to California to look for gold.)On the way to California, Strauss sold almost all of his dry goods. He had only one thing left-- some _ . In California, Strauss tried to sell the canvas to the gold miners . He said they could make tents from the canvas. But they weren't interested in canvas for tents. Strauss didn't know what to do with the canvas. Then, he had an idea. Strauss could see that the miners needed new pants. There were holes in their pants because the fabric wasn't strong. He decided to make the canvas into pants. They called them " _ ". Later, Strauss stopped using canvas and used a different fabric. It was a heavy cotton fabric-- the same kind people wear today. Levi Strauss died in 1902. He never married and left his money to his nephews. He left the world much more -- the jeans that so many people wear. Options: A Tent. B Pants. C A very strong fabric. D A thing which is used to make all kinds of trousers. Answer: C A very strong fabric. Question:
Answer: What is canvas?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Is any economist so dull as to criticise Christmas? At first glance,the holiday season in western economies seems a treat for those concerned with such vagaries as GDP growth.After all,everyone is spending;in America,retailers make 25% of their yearly sales and 60% of their profits between Thanksgiving and Christmas.Even so,economiwsts find something to worry about in the nature of the purchases being made. Much of the holiday spending is on gifts for others.At the simplest level,giving gifts involves the giver thinking of something that the recipient would like-he tries to guess her preferences,as economists say-and then buying the gift and delivering it.Yet this guessing of preferences is not easy;indeed,it is often done badly.Every year,ties go unworn and books unread.And even if a gift is enjoyed,it may not be what the recipient would have bought if they had spent the money themselves. Interested in this mismatch between wants and gifts,in 1993 Joel Waldfogel,then an economist at Yale University,sought to estimate the difference in dollar terms.In a research,he asked students two questions at the end of a holiday season:first,estimate the total amount paid (by the givers) for all the holiday gifts you received;second,apart from the sentimental value of the items,if you did not have them,how much would you be willing to pay to get them? His results were gloomy:on average,a gift was valued by the recipient well below the price paid by the giver. In addition,recipients may not know their own preferences very well.Some of the best gifts,after all,are unexpected items that you would never have thought of buying,but which turn out to be especially well picked.And preference can change.So by giving a jazz CD,for example,the giver may be encouraging the recipient to enjoy something that was ignored before.This,a desire to build skills,is possibly the hope held by many parents who ignore their children's desires for video games and buy them books instead. Finally,there are items that a recipient would like to... Options: A Price is nothing but the factor when you give gifts. B Chocolates will be blamed when people receive them as gifts. C The receivers often overestimate the values of gifts. D Wants do not always correspond to needs in gift-giving. Answer: D Wants do not always correspond to needs in gift-giving. Question:
