input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Grasslands need time to rest when cattle and other animals feed on them. Moving animals from one area of pasture to another can provide the time needed for new growth. This is called rotational grazing . Rotational grazing is good for the land and the animals, and it can save money. This form of grazing can reduce the need for pesticide treatments by reducing the growth of weeds. And it can limit the need for chemical fertilizers by letting animal wastes do the job of natural fertilizer. Rotational grazing can even help prevent wildfires by keeping grasslands in good condition. Letting animals feed continually and intensively in the same grazing areas can require costly replanting. Animals eat the most desirable growth first. When that keeps happening, the roots do not have enough time to recover. As a result, less desirable plants may replace them. Intensively used grasslands are also harmed as the soil is continually crushed under the weight of heavy animals. While rotational grazing can save money over time, it also requires planning. And that starts with a good map to mark fences, water supplies and grazing areas. Changing methods of grazing also requires time. Farmers may want to put up electric fences to enclose grazing areas, called paddocks. The paddocks will need water. Some farmers design a path for animals from different paddocks to drink from a common watering place. Farmers can start rotational grazing by removing animals from a pasture when the grass is eaten to less that five centimeters. The pasture is then kept empty until the grass grows to more than fifteen centimeters high. Sheep and goats may require special preparations. They may need stronger fences than other animals. And while they eat the grass, they may need guard animals to protect them from animals that would like to eat them. Options: A divide the pasture into paddocks B encourage animals to get around C stop animals staying at one place D provide water supplies for animals Answer: A divide the pasture into paddocks Question:???
output answer: The function of putting up electric fences is to _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or dec ide it' s still OK to eat? If you're like most people, you eat it. Maybe you follow the "5-second rule", which claims foods are safe to eat if you pick them up within 5 seconds after dropping them. But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria to make you sick. Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick. One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly. But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile , and carpet. They placed a piece of bread and a piece of bologna on each surface for 5,30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick. So forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. This time, be careful not to drop it! Options: A throw away dirty toast immediately and go away B pick up the toast as quickly as possible and eat it C eat the toast within 5 seconds and feel pleased D get another piece of clean toast quickly and eat it Answer: B pick up the toast as quickly as possible and eat it Question:
----
Answer: After dropping a piece of toast , a person who follows the "5-second rule"will

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Recent developments in astronomy have made it possible to detect planets in our own Milky Way and in other galaxies. This is a major achievement because,in terms,planets are very small and do not give out light. Finding planets is proving hard enough, but finding life on them will prove _ more difficult. The first question to answer is whether a planet can actually support life. In our own solar system,for example,Venus is far too hot and Mars is far too cold to support life. Only the Earth provides ideal conditions,and even here it has taken more than four billion years for plant and animal life to evolve . Whether a planet can support life depends on the size and brightness of its star, that is its "sun". Imagine a star up to twenty times larger, brighter and hotter than our own sun. A planet would have to be a very long way from it to be capable of supporting life. On the contrary, if the star were small,the life--supporting planet would have to have a close orbit round it and also provide the perfect conditions for life forms to develop. But how would we fund such a planet? At present, there is no telescope in existence that is capable of detecting the presence of life. _ . It is impossible to look for life on another planet using earth--based telescopes. Our own warm atmosphere and the heat generated by the telescope would make it impossible to detect objects as small as planets. Even a telescope in orbit round the earth like the very successful Hubble telescope,would not be suitable because of the dust particles in our solar system. A telescope would have to be as far away as the planet Jupiter to look for life in outer space because the dust becomes thinner the further we travel towards the outer edges of our own solar system. Once we detected a planet,we would have to find a way of blocking out the light from its star, so that we would be able to "see" the planet properly and analyze its atmosphere. In the first instance, we would be looking for plant life,rather than "little green men" .... Options: A the Hubble telescope is suitable for any space exploration B we humans will be visited by little green men C finding life on another planet will be shocking news D no achievement has been made in astronomy Answer: C finding life on another planet will be shocking news Question:
