PROBLEM: Article: Narayanan Krishnan was a bright, young, award-winning chef with a five-star hotel group in Switzerland. But a quick family visit home before heading for Europe changed everything. He saw a very old man under a bridge eating his own human waste for food while visiting a friend in the south Indian city of Madurai in 502. Shocked by this, Krishnan gave up his job within the week and returned home for good, convinced of his new cause. "That inspiration is a driving force still inside me as a flame--to serve all the mentally ill and the people who cannot take care of themselves," Krishnan said. He founded the organization Akshaya Trust in 503. In Hindu mythology , Goddess Annapoorani's "Akshaya bowl" fed the hungry endlessly, never using up its resources. Now 14, he has served more than 1.2 million meals--breakfast, lunch and dinner to India's homeless and the poor. Krishnan's day begins at 4 a.m. He and his team cover nearly 110 miles, routinely working in temperatures topping 100 degrees Fahrenheit. The hot meals he delivers are simple, tasty vegetarian food he personally prepares, packs and often hand-feeds to nearly 400 people each day. Krishnan carries the barber's tools and is trained in eight haircut styles that, along with a fresh shave, provide extra dignity to those he serves. He says many of the homeless seldom know their names or birthplaces, and none has the ability to beg, ask for help or offer thanks. They may be unfriendly or ill-willed because of their conditions, but Krishnan says this only makes him offer help more willingly.
Answer: knew the condition of the mentally ill

SOLUTION: During his visit home, Krishnan _ .

PROBLEM: Article: Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer. Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma , a type of skin cancer. More than 1,200 Australians die every year from the disease. Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment. "We believe it works by getting into the tumor cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It's not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision ,"he said. "It's useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred." About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal. Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging. Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg. "I've had a lot of friends who just said 'I thought it was just, you know, I'll get a mole cut out and that's it', whereas I don't think people realize how much danger they're putting themselves into and how easy it is to stop something like this happening to you just from doing little things,"said Marock. Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned , are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.
Answer: it can be effective in treating skin cancer

SOLUTION: The information about Rose Bengal is wrong EXCEPT that _ .

PROBLEM: Article: Guinness World Records, the global authority on record-breaking achievements, presented China Central TV (CCTV) the world record for Most Watched National Network TV Broadcast for its annual Spring Festival Gala show. The program, which is produced especially to celebratethe Chinese New Year, had a unique reach of 498,659,000 viewers on CCTV-1, 3 and 4 in 2012 , making it the most watched national variety entertainment show in the world.

The figure refers to viewers on any one of the three channels, therefore excluding duplications . This represents almost 40% of the China TV population aged 4 years or above. Commenting on CCTV's incredible record achievement which is based on reach of audience, Alistair Richards said, "It is fitting that we celebratethis amazing achievement at MIPTV. National networks have the power to move nations and CCTV's Spring Festival Gala is the ultimate example. It reaches nearly half a billion people on the biggest holiday of their year." CCTV Vice President Luo Ming, who accepted the Guinness World Records certificate on behalf of CCTV, said, "Chinese New Year is a special time for families in China and our Spring Festival Gala has been the traditional TV entertainment highlight for three decades.
