input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Annealing is a way of making metal softer by heating it and then letting it cool very slowly. If metal is heated and then cooled very quickly , for example by dipping it in water , it will be very hard but also very brittle ---that is , It will break easily. Metal that has been annealed is soft but does not break as easily . It is possible to make metal as hard or as soft as is wished, by annealing it. The metal is heated, and allowed to cool slowly , for a certain length of time. The longer the heated metal takes to cool slowly , the softer it becomes . Annealing can also be used on other materials, such as glass. Options: A It can be heated and then cooled quickly B It can be cooled and then heated slowly C It can be heated and then cooled slowly D It can be cooled and then heated quickly Answer: C It can be heated and then cooled slowly Question:

output: As suggested by the text , how can glass be made less brittle ? _

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Researchers in over 80 nations are taking part in a project to conduct a decade-long census of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion. In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish and other marine creatures. Elsewhere in the world's oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life. "There are about 2,000 scientists worldwide involved," said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. "Everywhere they've gone they've found new things," he says. "The ocean basically is unexplored from the point of view of marine living things." Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration routes and to discover places where sea life gathers. According to Ron O'Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. "90% of all the information we have is from the top hundred meters of the ocean," O'Dor states. And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things. Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census --which some say is only a small part of all the creatures living in the sea. Options: A About 2,000 scientists from America are involved in the project. B The census of sea life will last for ten years. C 230,000 new marine animals have been found. D The sea floor is at a depth of 400 meters. Answer: B The census of sea life will last for ten years. Question:

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: Each year, about 10,000 to 100,000 animal species die off. They join the countless species that have gone extinct over the course of Earth's history - and extinction means forever. At least it used to. Scientists are now closing in on the ability to bring back extinct species. No, this doesn't mean the plot of Jurassic Park is going to become a reality. Researchers need DNA to bring back a species. DNA is the chemical that carries the structure for a living thing. Dinosaurs have been gone too long for any of their DNA to remain in fossils. But there's a very real chance that we will be able to bring back more recently extinct species. This could even include Ice Age animals like the woolly mammoth. In 2003, a team of Spanish and French scientists re-created the Pyrenean ibex, which had gone extinct three years earlier. The new animal didn't survive long, but scientific advances should improve the success rate. In January, Australian scientists announced that they were on their way to bringing back the gastric brooding frog. That we can bring species back doesn't mean that we should. There may be benefits to reviving a species. But there's no way to know how it will turn out. For example, would a passenger pigeon fit into its old habitat? Or might it crowd out existing species? Environmentalists worry that our ability to bring species back might cut down support for the hard work of traditional conservation. Why worry about preserving a wildlife habitat or fighting poachers if we know we can just make up for our mistakes? But those extinctions are our mistakes to correct, which may give us an obligation to do so. As businessman and environmentalist Stewart Brand recently said, "Humans have made a huge hole in nature. We have the ability now to repair some of that damage." We would do well to remember the lesson of Jurassic Park: Proceed with caution. Options: A That scientists cannot make up for the mistakes that they made in the past. B That traditional conservation might be of no use by bringing species back. C That scientists could lack the ability to bring back extinct species to life. D That species that will be brought back to life will not survive long. Answer: B That traditional conservation might be of no use by bringing species back. Question:

A: What makes environmentalists worried according to the passage?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Researchers may tell us that spending money on experiences produces more happiness than spending money on things. Going to a bar with friends is always pleasurable in slightly different ways. However, on the other hand, a table may also give us lots of positive experiences sometimes. I just moved from New York City to suburban Pennsylvania, It's been quite a change of pace, with some positives and negatives, One of the best parts is that I'm spending more time outside. I quite enjoy staying outside, especially eating outside. I had a goal to eat outside as often as possible this summer, so one of my first purchases for the new house was a table and a set of chairs for the yard. Is my yard table a thing or an experience? It's clearly a thing and yet it enables the experience of eating outside. I love eating outside, and so my yard table is one of my favorite purchases, ever. Therefore I find the dividing line between things and experiences is more nuanced than at first glance. However, to be happy, the most important thing is what kind of purchases you have made. Sometimes we may all have purchases that seem like a waste of money like probably half the clothes in our closets, but how does this happen?' There are many reasons for why this happens. The biggest is that we spend a lot of our time working to earn money to buy things. The problem is that we buy a lot of stuff that we don't actually need. There's nothing worse than looking in your closet and realizing how many hours you spent laboring to buy things you never wear. But how about a table that lets you enjoy being outside in the summer? That's worth every minute and penny and from it you will also get more happiness. Options: A How you can spend your summer outside. B How you can make moving enjoyable. C What the best purchase is. D Why people spend a lot of money on things. Answer: C What the best purchase is. Question:???
