Ques:Article: The sun is a huge, hot, bright star. It is important because without it there would be no life on Earth. The sun gives us light and heat. All living things need light and heat from the sun to live. Plants need light and heat to grow. They use the light from the sun to make food. We cannot make our own food, but plants can. All the food we eat comes from plants in a food chain which starts with the sun. For example, Animals need sunlight, too. Just like us, their food comes from a food chain which begins with the sun and the plants. sun- leaf- caterpillar -bird sun- seaweed -small fish- whale Sunlight means we can see during the day. If there was no sun, it would be dark all the time. Even when the sky is cloudy, the sunlight is very strong and it shines through the clouds. Question: All the food we eat comes from _ . And it starts with the _ . Yes or no, is the answer "plants; star"?

Ans:No

Ques:Article: Convection vs. Conventional Ovens If you are in the market for a new oven and you've already begun shopping for one, you've probably noticed that there are a few different types. Two of the most popular oven types are conventional and convection. The difference in these two types of ovens is the way in which the heat in the oven is spread during the cooking process. Convection ovens A convection oven uses a fan which is usually located on the back side of the oven. The purpose of the fan is to force the heated air inside of the oven and circulate it around the item being cooked. The heater air is constantly pushed over and around the food, and therefore a convection oven cooks food much faster than a conventional oven. Not only does a convection oven cook food more quickly than a conventional oven, but it can also thoroughly cook food at lower temperatures. The average amount of time saved when cooking with a convection oven is about 20 percent of the food's normal cooking time. The temperature a convection oven uses to cook food is also about 20 percent lower than a recipe's suggested cooking temperature. Convection ovens are speedier and more efficient than conventional ovens, and therefore may be more expensive. However, professional chefs from around the world swear by them and rely on them for delicious tasting food. Also, since the air circulation in a convection oven is the same throughout, food will cook at the same rate no matter where it is placed in the oven....on the top or bottom rack or near the front or back. Conventional Oven Traditionally, most personal residences in the United States come equipped with a modern conventional oven. These are the most common types of household ovens, and are used every day to cook all sorts of meals, desserts, breads, and many other types of food. Conventional ovens are similar to convection ovens in that they both cook food using heat. They both have the ability to use either gas or electricity, depending on the hook-up in a home. Some may use either... Question: Which of the following is True of both convection ovens and conventional ovens? Yes or no, is the answer "It uses either gas or electricity to provide heat."?

Ans:No

Ques:Article: When you think of environmental problems you probably think of pollution, but the poaching of wild animals is one, too. Poaching has worried environmentalists for years and, despite laws, this terrible crime has yet to be stopped. Poaching is a serious problem, especially in Africa and Asia. This crime is done for commercial profit , meaning hunters kill animals illegally and sell their most worthy parts. Although poachers usually hunt tigers, elephants and rhinos, they kill sharks and whales, too. This illegal hunting has led to decreasing populations of many species. Many nations have banned poaching, but enforcement is difficult. The small number of police officers trained to deal with this creates an unfair advantage for poachers. Poachers usually kill animals for only one product: tigers are killed for their striped fur, elephants their ivory tusks and rhinos their large horn. The bodies of the animals are left to rot. Sharks' fins are cut off and their bodies thrown back into the ocean. Without fins they can't swim and will die. The illegally obtained fins are used to make shark fin soup. The laws that "protect" animals are no more than pieces of paper. The current poaching bans need better enforcement, and I have a plan. The number of enforcers needs to be increased so that there are enough to watch the herds and make sure poachers can't shoot the animals. The reserve parks in Africa should become a huge zoo so that the animals can move but within a fenced area. Another idea is to build a concrete enclosure instead of fences. Watchtowers could be constructed so enforcers can monitor a wide variety of poacher targets. This may not completely end the problem, but it would slow it down. Poaching is a serious problem and a criminal act. The effects of poaching will be felt for centuries to come, and if there are any still alive, the only place to see animals might be in a zoo. Question: The purpose of this passage is to _ . Yes or no, is the answer "provide some suggestions on banning poaching"?

Ans:No

Ques:Article: An Australian inventor has designed and built an environmentally friendly ferry that uses solar and wind power to transport people around Sydney Harbor. Robert Dane and his Solar Sailor were given the top prize at the Australian Design Awards recently. The Solar Sailor has been in use for six months. It uses four sources of energy for its power -- solar, wind, battery power with stored solar energy and a fuel generator in store all controlled by computers. The ferry can travel up to 7.5 knots on just wind and solar power. It's solar wings and fiberglass solar panels which not only take in sunlight and store it in batteries, but also act as sails. "We angle our solar panels to the sun in two planes , which increases the amount of energy we get from the sun by 40 percent," Dane says. "And also we can use that same structure to do another job, which is also the sail, and so these wing sails actually push the ferry forward just like a soft sail does." Computers check the sun and wind and angle the solar wings to take in the most sunlight. If there isn't much wind or it is a cloudy day, energy stored in the batteries runs the electric motor for up to five hours. "If the batteries are too low, then the computer turns the generator on so the boat is always able to meet a commercial schedule, or get from point A to point B no matter what," Dan explains. Dane got his idea for the Solar Sailor from a book on insects. He was amazed how insects use their wings to collect solar energy to warm themselves. "When I read that, I realized there was a good example in nature for what we were going to do, which was to use a solar wing to collect solar energy and also to sail," he says. Question: What is the purpose of writing this article? Yes or no, is the answer "To introduce a new invention."?

Ans:
No
