Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Input: Consider Input: Context: From a human point of view, natural resources can be classified as either renewable or nonrenewable. Renewable resources are natural resources that are remade by natural processes as quickly as people use them. Examples of renewable resources include sunlight and wind. They are in no danger of being used up. Metals and some other minerals are considered renewable as well because they are not destroyed when they are used. Instead, they can be recycled and used over and over again. Living things are also renewable resources. They can reproduce to replace themselves. However, living things can be over-used or misused to the point of extinction. For example, over-fishing has caused some of the best fishing spots in the ocean to be nearly depleted, threatening entire fish species with extinction. To be truly renewable, living things must be used wisely. They must be used in a way that meets the needs of the present generation but also preserves them for future generations. Using resources in this way is called sustainable use. Nonrenewable resources are natural resources that cant be remade or else take too long to remake to keep up with human use. Examples of nonrenewable resources are coal, oil, and natural gas, all of which are fossil fuels. Fossil fuels form from the remains of plants and animals over hundreds of millions of years. We are using them up far faster than they can be replaced. At current rates of use, oil and natural gas will be used up in just a few decades, and coal will be used up in a couple of centuries. Uranium is another nonrenewable resource. It is used to produce nuclear power. Uranium is a naturally occurring chemical element that cant be remade. It will run out sooner or later if nuclear energy continues to be used. Soil is a very important natural resource. Plants need soil to grow, and plants are the basis of terrestrial ecosystems. Theoretically, soil can be remade. However, it takes millions of years for soil to form, so from a human point of view, it is a nonrenewable resource. Soil can be misused and eroded (see Figure 25.9). It must be used wisely to preserve it for the future. This means taking steps to avoid soil erosion and contamination of soil by toxins such as oil spills. Some of the resources we depend on the most are energy resources. Whether its powering our lights and computers, heating our homes, or providing energy for cars and other vehicles, its hard to imagine what our lives would be like without a constant supply of energy. Fossil fuels and nuclear energy are nonrenewable energy resources. People worldwide depend far more on these energy sources than any others. Figure 25.10 shows the worldwide consumption of energy sources by type in 2010. Nonrenewable energy sources accounted for 83 percent of the total energy used. Fossil fuels and the uranium needed for nuclear power will soon be used up if we continue to consume them at these rates. Using fossil fuels and nuclear energy creates other problems as well. The burning of fossil fuels releases carbon dioxide into the atmosphere. This is one of the major greenhouse gases causing global climate change. Nuclear power creates another set of problems, including the disposal of radioactive waste. Switching to renewable energy sources solves many of the problems associated with nonrenewable energy. While it may be expensive to develop renewable energy sources, they are clearly the way of the future. Figure 25.11 represents three different renewable energy sources: solar, wind, and biomass energy. The three types are described below.

Solar cells can turn sunlight into electricity. The energy in sunlight is virtually limitless and free and creates no pollution to use. Wind energy is energy provided by the blowing wind. Wind turbines, like those in Figure 25.11, can turn wind energy into electricity. The wind blows because of differences in heating of Earths atmosphere by the sun. There will never be a shortage of wind. Biomass energy is energy provided by burning
Question: If natural gas continues to be used at current rates, it will be used up in a few

Output: decades.

Input: Consider Input: Context: Marino finished the game with 29 out of 50 pass completions for 318 yards, 1 touchdown, and 2 interceptions. Clayton was the top receiver of the game, with 6 receptions for 92 yards. Walker returned 4 kickoffs for 93 yards and gained 15 yards on 2 punt returns. Nathan was the Dolphins leading rusher with 18 yards, while also catching 10 passes for 83 yards. Craig had 58 rushing yards, 77 receiving yards, and 3 touchdowns. He was the first player ever to score 3 touchdowns in a Super Bowl, and his 2 touchdown catches also tied a Super Bowl record. Tyler led San Francisco in rushing with 65 yards, and also caught 4 passes for 70 yards. Clark caught 6 passes for 77 yards. Board recorded 2 sacks. McLemore recorded 51 punt return yards, the second most in Super Bowl history. Sports Illustrated called 49ers defensive tackle Gary Johnson (American football) the Super Bowls "unofficial defensive MVP" after he recorded one sack, flushed Marino out of the passing pocket numerous times, and had four unassisted tackles.
Question: Who had a higher average of yards per caught pass, Clayton or Clark?

Output: clayton

Input: Consider Input: Context: Qi Baishi (1863~1957) is one of the best-known contemporary Chinese artists. His life shows he achieved success by combining talent with hard work. He was born in a peasant family. At 11 he was sent to learn carpentry . Through his work he got to know some local scholars. One of them, Hu Shenyuan, offered to teach his painting and poetry. During this period he earned his living by painting portraits and selling his works. Gradually he developed a reputation as an artist as well as a carpenter. In those years he devoted himself to poetry, calligraphy , and seal-carving. Although he admitted he was a versatile artist, his own criteria of his successes placed poetry first, seal-carving second, calligraphy third, and painting last. From 1902 to 1916, Qi toured the country five times, and he left his footmarks in many cities, such as Beijing and Hongkong. The trips broadened his vision and changed his style. In 1917 he settled down in Beijing, where he met many artists and scholars, and made friends with Chen Shizeng. Chen advised him not to _ early masters and to form his own style. Through long years of practice, Qi Baishi evolved a distinctive personal style. The subjects of his painting were wide and various, and the flowers, birds, fish, prawns , and insects he painted are most admired by his public. To improve his technique of painting prawns, he raised some at home and frequently observed their movements. He wrote in his diary about how he had changed his method of painting prawns: "At first my prawns owned a reasonable similarity, then they became even more realistic, and finally light and dark color1s became properly contrasted. These are the three changes." Qi Baishi was able to portray the same object in either the xieyior thegongbistyle. When he painted a dragonfly in a detailed manner, he even drew the veins in its wings. When he adopted a , free style, he used only a few dry, expressive strokes to form it. What is fascinating about his work is that in some pictures both methods are used.
Question: In his early life, what was Qi Baishi famous for?
Output: poetry
