Read the following article and select the best answer. Article: Soaring divorce rates around the globe are _ the environment ,American researchers suggested in a study released Monday . Michigan State University researcher Jianguo "Jack "Liu and his assistant Eunice Yu said the increasing number of divorces leads to more households with fewer people and greater consumption of water and energy .They said housing units require space ,construction materials and fuel to heat and cool ,regardless of the number of inhabitants . For example ,in the United States in 2005, divorced households consumed an extra 73 billion kilowatt hours of electricity and 627 billion gallons of water ,An additional 38 million extra rooms required heating and lighting that same year due to divorced households . "A married household actually uses resources more efficiently than a divorced household ", Liu said ,He said that in cohabitating households ,people will watch the same television ,share the air conditioning and heat and use the same refrigerator ,all things that use energy at a regularly stable rate regardless of the number of uses . Liu said he was not condemning divorce ," Some people really need to get divorces "He said cohabitation ---- whether by a family ,friends or even in a commune ------ was simply a more environmentally friendly option ,Additionally ,the researchers noted that trends other than divorce are also changing family living structures ,such as the end of multiple generations of a family sharing a home and people remaining single longer . "People's first reaction to this research is surprise ,and then it seems simple ":Liu said in a release " But a lot of things become simple after research is done .Our challenges were to connect the dots and quantify their relationships People have been talking about how to protect the environment and combat climate change ,but divorce is an overlooked factor that needs to be considered . " He said the increasing energy demands caused by divorce should be considered by governments when they are creating environmental policies . Question: It can be inferred from the passage that _ - divorced households will stimulate the sales of products - married households are more willing to protect the environment - divorced households contribute more to the society's development - divorce is not taken into account when people are protecting the environment

divorce is not taken into account when people are protecting the environment

Article: The snow cap of Mount Kilimanjaro, famous in literature and beloved by tourists, initially formed some 11,000 years ago, but will be gone in two decades, according to researchers who say the ice fields on Africa's highest mountain shrank by 80 percent in the past century. Lonnie G. Thompson,one professor from Ohio State University, said measurements using modern navigation satellites show that the oldest ice layers on the famous mountain were deposited during an extremely wet period starting about 11,700 years ago.The mountain appears in literature, most notably Ernest Hemingway's "The Snows of Kilimanjaro" and some ancient beliefs in Africa hold the mountain to be a sacred place. But a temperature rise in recent years is destroying the 150-foot-high blocks of ice that gave Kilimanjaro its unique white cap."The ice will be gone by about 2030," said Thompson. The disappearing ice already has reduced the amount of water in some Tanzanian rivers and the government fears that when Kilimanjaro is bald of snow the tourists will stop coming. "Kilimanjaro is the number one foreign currency earner for the government of Tanzania," said Thompson. "It has its own international airport and some 20,000 tourists every year. The question is how many will come if there are no ice fields on the mountain." Africa was not alone in the global drought. Thompson said other records show that civilizations during this period collapsed in India, the Middle East and South America. Researchers put markers on the ice field blocks in 1962 and Thompson said measurements using satellites show the summit of the ice has been lowered by about 56 feet in 40 years. The _ of the ice also has moved back more than six feet in the past two years, much smaller than before. "That's more than two meter's worth of ice lost from a wall 164 feet (50 meters) high," said Thompson. "That's an enormous amount of ice."

Read the following article and select the best answer. Article: When we give our kids holiday gifts, many of us can't wait to hear their appreciative cries of"thank you!"once the wrapping gets ripped off. But here's a tip: You'd be wise not to expect much gratitude from them for what they receive. Gratitude can make us happier, healthier, and even fitter. But do the kids show their gratitude for the stuff we buy them? All the research I've done has convinced me that it won't happen. One mom told me that when she asked her 16-year-old son to thank her for buying him a cellphone, he said, "But that's what moms should do." From a teenager's angle, it's a parent's responsibility to take care of the family. According to Dunham, Yale's assistant professor of psychology, "When teenagers code it that way, a gift is no longer something given freely and voluntarily"--it's just mom and dad living up to their obligation. Parents do have the right to demand good manners and children should thank sincerely whoever gives them something. But kids can't know how blessed they are unless they have a basis for comparison. And they don't learn that by a parent complaining that they're ungrateful. We need to give our children the gift of a wider world view. Show by example that gratitude isn't aboutstuff--which ultimately can't make any of us happy anyway.It's about realizing how lucky you are and paying your good fortune forward. You can collect all the charitable appeals and sit down together with the kids to go through them. You set the budget for giving and the kids decide how it's distributed. Once the conversation about gratitude gets started, it's much easier to continue all year. Also you can set up a family routine at bedtime where kids describe three things that have made them grateful. When kids go off to college, you can text them a picture each week of something that inspires your appreciation. Teaching children to focus on the positive and appreciate the good in their lives is perhaps the greatest gift we can give them. And we can all learn together that the things that really...
