Example Input: (CNN) "Yessssss!" was my reaction to hearing the news that the U.S. Food and Drug Administration intends to regulate e-cigarettes, hookahs, vape pens, e-pipes and other electronic nicotine delivery products. As a family physician, I often have patients ask me about e-cigarettes. Some have seen advertisements and are wondering what they are; some have simply heard that e-cigarettes are safer than traditional cigarettes and want to know if this is true. E-cigarettes are included in the category of ENDS -- Electronic Nicotine Delivery Systems -- products that use a liquid containing nicotine and varying amounts of flavor, glycerin, propylene glycol and other ingredients. This liquid is heated into an aerosol that users then smoke. It is often referred to as "vaping."Jennifer Caudle says FDA regulation of electronic nicotine delivery systems is overdueMore research needed on long-term effects, especially as youth use skyrockets, she says 
 Questions:There is no doubt that the use of these products has surged in recent years and business has grown; it is possible that _ oversight might affect this growth. (A) CNN (B) Yessssss! (C) U.S. Food and Drug Administration (D) Electronic Nicotine Delivery Systems (E) Jennifer Caudle (F) FDA

Example Input: (CNN) A judge in Massachusetts on Friday sentenced a teenager to serve at least 40 years in prison for killing, raping and robbing his high school math teacher. Philip Chism,17, stood in handcuffs, his face expressionless, as sentences by Superior Court Judge David Lowy were read aloud, following emotional victim impact statements from family and friends of the slain teacher, Colleen Ritzer. "He is pure evil, and evil can never be rehabilitated," said Peggie Ritzer, Colleen's mother, furious because Chism would eventually be eligible for parole. "We will never get a second chance and neither should he." Chism did get a life sentence on the murder charge but could have gotten parole after 25 years because of recent court rulings that limit sentences for juvenile murder defendants."He is pure evil, and evil can never be rehabilitated," victim's mother saysPhilip Chism, 17, will have to serve at least 40 years in prisonHe was convicted of killing, raping and robbing his high school math teacher in 2013
