[Q]: Article: Mary Jean Price Walls graduated second in her class in 1950.She had high hopes when she applied to a local college,Southwest Missouri State College.But after sending off her application,she spent months waiting for a reply.It never came. Worse than simply being denied admission ,the school didn't reply to her at all.It wasn't a matter of her school records,but of her skin color:Wallsis African American,and in those days,that fact alone closed a lot of doors. "I was sad and I was hurt,"Walls toldABCNews."I did not expect the skin color would affect my application.I thought I could go to university like other students." Four years later,the government declared that all schools should not discriminate against African Americans-- but it was too late for Walls.She'd moved on with her life, becoming a wife and a mother,and working as an elevator operator.She retired last year,at the age of 77. She stayed quiet about the unfairness she'd faced in Missouri State.Her son,Terry,went through school records and found that she'd been the first black student to ever apply to the college.Today,four percent of the Southwest Missouri State College body is African American--including Terry. Although it's too late for Missouri State to change the past,the school is awarding Walls with an honorary degree from the school.While she knows it's too late for herto change the course of her own life with the degree,it's a chance for her to show her family that Missouri State has changed in the last 60 years,and there's not a single door closed to them anymore.

[Q]: Article: As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow in the dark. The efforts have produced two rabbits out of a litter of eight that went from being a normal, soft white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of the cooperation between scientists from universities in Turkey and Hawaii. The rabbits glow to show that a genetic operation technique can work efficiently. "The green is not important at all--it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor, Stefan Moisyadi. To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Then those embryos were put into the mother. Similar experiments have resulted in glowing cockroaches and cats. Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. "The final goal is to develop animals that are able to produce beneficial molecules in their milk that can be cheaply extracted , especially in countries that cannot afford big factories that make drugs, which usually cost US$1bn to build. Then they will be able to produce their own protein-based medication in animals," Moisyadi said. The rabbits are expected to live as long as non-glowing rabbits, but Moisyadi said he understands people can object to this kind of experimentation involving live animals. "To the people against, I say: think, what are the benefits and what is the harm?" Moisyadi said. "And if the benefits outweigh the harm, let's go with the benefits." Moisyadi started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.
Question: What do we know about the glowing rabbits?
Options: (A) Their fur became green after the experiment. (B) They were chosen from a special species of rabbits. (C) The color1 that they glow isn't of interest to scientists. (D) They live shorter lives than ordinary rabbits.
[A]: C

[Q]: Article: A 15-year-old American has become the youngest person to climb the highest mountains on each of the seven continents, completing the feat by summiting Antarctica's Mount Vinson over the weekend. Jordan Romero, who last year at age 13 became the youngest person to climb the world's tallest peak Mt Everest, was descending to base camp on Sunday after reaching the summit of Vinson Massif with a team that included his father and stepmother, according to his team's website. "We're at the roof of Antarctica," a member of Team Jordan said in a webcast from near the 4897-metre peak on a frigid but "legendary day". Romero beat the record previously held by Britain's George Atkinson, who in May completed the seven ascents at the age of 16. The junior mountaineer from Big Bear Lake, California has been hooked on climbing from an early age. When he was just 10, he became the youngest person to climb Mt Kilimanjaro, Africa's highest peak at 5895 meters. Before his 11th birthday, he had another world record under his belt, summiting Europe's Mt Elbrus, in Russia's Caucasus mountains, in July 2007. Five months later, it was the 6962-metre Mt Aconcagua in Argentina, followed by Alaska's Mt McKinley at 6194 meters. In September 2009 at age 13, he climbed Indonesia's Carstensz Pyramid, at 6194 meters the tallest island peak in the world, breaking another record. Eight months later in May 2010, he climbed Everest, and ever since he and his team had been preparing for his Antarctic expedition. "Looking forward to tomorrow, and we'll make you guys proud and promise we'll come back home safe and sound," Romero said in a webcast on Saturday, hours before he began the final ascent to Mt Vinson's summit. The team had intended to reach the top on Christmas Day, but ideal weather and good progress allowed them to summit a day ahead of schedule.
