Article: The UN weather agency warned on Tuesday there was a good chance of an "El Nino" climate phenomenon in the Pacific Ocean this year, bringing droughts  and heavy rainfall to the rest of the world. The World Meteorological   Organization (WMO) said its modeling suggested a "fairly large potential for an El Nino, most likely by the end of the second quarter of 2016". The El Nino phenomenon occurs every two to seven years, when the trade winds that circulate surface water in the tropical   Pacific start to weaken. WMO pointed out Tuesday that since last December, trade winds had weakened and there had been a significant warming of the waters below the surface in the central Pacific. "While  there is no guarantee this situation will  lead to an El Nino event, the longer the trade winds remain  weakened, and subsurface temperatures stay significantly warmer than average, the higher chances are," it said. Two thirds of climate models predicted that the phenomenon would begin sometime between June and August, with one-fifth suggesting it could start as early as May, and the remaining predicting no El Nino this year, it said. It is often followed by a return swing of La Nina, which is characterized by unusually cool ocean surface temperatures in the central and eastern tropical Pacific. "El Nino has an important warming effect on global average temperatures," Jarraud cautioned, stressing that combined with warming from greenhouse gases such events had "the potential to cause a sharp rise in global average temperature". Question: According to the text, what might be the percentage of no "El Nino" this year? Options: A: 13%. B: 20%. C: 67%. D: 87%.

Doctor Carson is an internationally recognized doctor at Johns Hopkins Hospital in Baltimore, Maryland. He has been the director of Pediatric Neurosurgery at the hospital for twenty-five years. At the age of thirty-three, he became one of the youngest doctors in the United States to hold that position. And he was the first African-American to have that position at Johns Hopkins Hospital. Ben Carson is known for his work as a brain surgeon for children. For example, in nineteen eighty-seven, he led a team of seventy doctors and nurses in an operation to separate two babies joined at the head. Earlier attempts by other on other babies had failed. Doctor Carson successfully performed the operation. Both babies were able to survive independently. Doctor Carson has written four books. His first book, "Gifted Hands," tells the story of his life. Benjamin Carson was born in nineteen fifty-one in Detroit, Michigan. As a boy, Ben was not a good student. In fact, he was the worst in his class. When his mother learned of his failing grades she asked her sons to read two library books every week. She limited the amount of time they watched television. And she told them to respect every person. Ben Carson soon became the top student in his class. He went on to study at Yale University, one of the best universities in the country, and later to medical school at the University of Michigan. Doctor Carson has received many awards and honors.
