Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Heritage is our legacy from the past, what we live with today, and what we pass on to future generations. Our cultural and natural heritage are both irreplaceable sources of life and inspiration. Places as unique and diverse as the wilds of East Africa's Serengeti, the Pyramids of Egypt, the Great Barrier Reef in Australia and the Baroque cathedrals of Latin America make up our world's heritage. What makes the concept of World Heritage exceptional is its universal application. World Heritage sites belong to all the peoples of the world, regardless of the territory on which they are located. The United Nations Educational, Scientific and Cultural Organization (UNESCO) seeks to encourage the identification, protection and preservation of cultural and natural heritage around the world considered to be of outstanding value to humanity. This is _ in an international treaty called the Convention Concerning the Protection of the World Cultural and Natural Heritage, adopted by UNESCO in 1972. UNESCO's World Heritage mission is to: encourage countries to sign the World Heritage Convention and to ensure the protection of their natural and cultural heritage; encourage States Parties to the Convention to nominate sites within their national territory for inclusion on the World Heritage List; encourage States Parties to establish management plans and set up reporting systems on the state of conservation of their World Heritage sites; help States Parties safeguard World Heritage properties by providing technical assistance and professional training; provide emergency assistance for World Heritage sites in immediate danger; support States Parties' public awareness-building activities for World Heritage conservation; encourage participation of the local population in the preservation of their cultural and natural heritage; encourage international cooperation in the conservation of our world's cultural and natural heritage. Question: From the passage, we can know that _ . Options: A: UNESCO signed the World Heritage Convention in 1972 B: World Heritage sites belong to the world and are of great value to humanity C: participation of the local population usually makes the conservation work easy D: UNESCO is an organization aimed at protecting the World Heritage
A: B

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: Ashleigh Fraser and Leah Guskjolen, both 18, wondered why they would not be allowed to wear nail polish or artificial nails during their training to become certified nursing assistants. But when they asked, the only response which they got was that "rules are rules." Not satisfied, the teens decided to explore the issue themselves. For their new study, Ashleigh and Leah, seniors at Willcox High School in Willcox, Arizona., borrowed materials from the hospital where they had been trained as nursing assistants. Ten nurses there agreed to give them little scrapings off the top side of their nails. Half of the participants had natural nails. The other half wore nail polish or fake nails on top of their natural nails. The teens grew bacteria from the scrapings on plates; these are plastic dishes with a gel that feeds bacterial growth. Natural nails produced an average of 4.3 bacterial colonies. In contrast, scrapings from nail polish or artificial nails produced an average of 17.5 colonies! Leah and Ashleigh had their answer to the question. Only natural nails are allowed because polished or artificial nails tend to harbor far more bacteria. The germs could be dangerous to sick patients. Leah notes that they are not the first to look at nails in a medical setting. Still, she says, "It is something that should be taken much more seriously than it is." To emphasize that, she points to the large list of similar studies she and Ashleigh uncovered during their research. When nurses touch patients, they often wear gloves, but many small tasks are performed bare-handed. The teens hope to raise awareness of how dangerous artificial nails can be in the medical setting. "What shocked me," Leah says, "is how unconcerned some of the nurses were. They did not think their nails were dangerous." Ashleigh agrees and observes that to preserve their manicures , nurses with polish or fake nails tended to scrub less vigorously when washing their hands. Their nails might look nice, but this might contribute to the large... Question: What did the two teenagers do for their study? Options: A: They visited many top scientists. B: They consulted the hospital's nurses. C: They collected experimental samples at a school. D: They grew germs from the scrapings on dishes.
A: D

Q: I'm taking a test and have to guess the right answer to the question after the article. Article: All it took was a slice of Xinjiang cake to spark heated debates online over China's policy on ethnic minorities . Since Monday, qiegao (cut cake) has been a trending topic on Sina Weibo, China's main Twitter-like microblogging service. The cake was a reference to Xinjiang's famed nut cake, sometimes known by its old Turkic name baklava, a popular pastry across Central Asia and the Middle East. In Xinjiang, they are sold by Uygur vendors on tricycles who are known to charge dubious prices depending on the time and season. The ethnic flare-up started after the Yueyang police from Hunan province posted a message on their official Weibo account. It reported a dispute in Pingjiang county over an overpriced piece of nut cake between a Xinjiang Uygur vendor and a villager named "Ling". Villager Ling got into a fight with a Uygur due to a misunderstanding. The verbal dispute eventually escalated into a fight and then a mass fight. As a result, two people were injured and Xinjiang nut cakes worth about 160,000 yuan (US$25,000) were destroyed. The total damage was worth 200,000 yuan which included a broken motorcycle and injuries to people. Local police have detained Ling. The 16 Uygur sellers were dully compensated and sent back to Xinjiang. "Yueyang police incident" quickly became one of the most popular topics on Weibo. Yueyang police removed the post shortly after. As of Tuesday night, the topic was still amassing more than 66,000 hits. The incident is just one of many similar cases of ethnic tensions across China, notably in Xinjiang province, where deeply entrenched social and racial frictions between the dominant ethnic Han Chinese and minority Uygur Muslims occasionally spark violence. Many Uygurs living in major Chinese cities are viewed by locals as thieves, crooks and even terrorists. Question: What's the best title of the passage? Options: A: World's most expensive baklava. B: Ethnic tensions across China. C: Pay attention to the Uygurs D: Misunderstanding caused by a fight
A: A
