Millions of people have entered its doors to see paintings by the world's fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery's 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem. In past times, the owners of paintings did not protect them from damaging changes in humidity and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over. Light is another enemy of paintings. Ultraviolet rays in light cause paintings to fade . Long ago, paintings often hung in dark churches and palaces. A coat of varnish was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age. To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new _ , many of the world's greatest paintings are being well protected for future generations to enjoy. Question: The text mainly tells us about  _  . Answer:
A:

input:  Now, answer this question: Read the following article and answer the question. Article: Like many languages spoken by people, Ayapaneco is dying. Only two people in the world still speak it, and they won't talk to each other. Spoken in Mexico for centuries, Ayapaneco is one of 68 surviving languages in the mainly Spanish-speaking nation. The two speakers are Manuel Segovia and Isidro Velazquez. Though they live only 500 meters from each other in the village, the two men seldom talk to each other. Daniel, an American expert, who is working to make a dictionary of Ayapaneco, says the two men "don't have a lot in common," and that Segovia can be "active" while Velasquez tends to mind his own business and stay at home. While Segovia still speaks to his wife and son in Ayapaneco, neither of them can manage more than a few words. Velasquez hardly speaks his native tongue any more. Daniel is working to preserve the language in dictionary form before its last surviving speakers pass away. According to Daniel, Ayapaneco and the other languages began dying out with the introduction of public Spanish education in the mid-20thcentury. For decades, local children weren't allowed to speak anything else. Many people to cities, starting in the 1970s, also helped the dying out of native languages. Ayapaneco is the name given to the language; Segovia and Velazquez call it "Nuumte Oote", which means "true voice". Neither man, however, speaks the same language. The dictionary will contain two versions  of the language when it comes out later this year. Those behind the dictionary aren't the only ones trying to save Ayapaneco. The National Language Institute plans to hold classes so that Segovia and Velasquez can pass on what they know to children. It is thought that there are about 6,000 languages spoken on earth and that about half will disappear over the next 100 years. Let's hope the "true voice" isn't one of them. Question: Segovia and Velasquez seldom talk to each other in Ayapaneco because they  _  . Answer:
A:
output: don't share the same interests

input:  Now, answer this question: Read the following article and answer the question. Article: I bent down in the shade under a sixty-foot-tall cactus , waiting for them to appear. The time was eight thirty in the morning. For seven mornings I had come to the same distant spot in the Sonoran Desert, in southern Arizona. I was here to watch the roadrunner, a small fast-running bird. I spotted two birds under a bush with red flowers. The roadrunners rushed out from under it. The birds moved rapidly on long skinny legs. Their feathers were brown and black. Their tails were seven inches long. Roadrunners use the tail for balance when running. That day, the roadrunners performed a courtship dance. They ran in wild circles. Suddenly, one stopped and stood still, its round eyes full of light. The second bird took hold of a small stick off the ground and presented it to the first, a gift serving as a symbol of their partnership. I returned to the spot each day, leaving bits of boiled chicken hoping they would return. Roadrunners eat snakes, lizards, mice, beetles, and spiders. Food is in short supply in the desert, so my offerings were welcome. The pair grew used to me. Soon after the pair finished building their nest six white eggs appeared in the nest bowl. In about three weeks, six roadrunner chicks, skin as black as coal, cried for food. Their parents brought food such as fence lizards and stink bugs. They fed their young until they were a month and a half old. Early one morning, a coyote came around, nose to the ground, for fresh bird meat. The roadrunners fearlessly drove the coyote away, but it was soon back. After three attacks the coyote went away for good, tail between its legs. I stopped watching the nest when the little roadrunners, at two months of age, were ready to live on their own. It was hard to break away from "my roadrunner family." Whenever I see a roadrunner now, rushing over the ground, I say hello to it as an old friend. Question: The author went to the Sonoran Desert to    _    . Answer:
