PROBLEM: (CNN) Just hours after two ISIS suicide bombers blew themselves up inside Brussels airport on the morning of March 22, 2016, Belgian police discovered their safe house/bomb factory, thanks to the testimony of the taxi driver who picked up the attackers and took them to the airport. In a trash can outside the residence on rue Max Roos in the Brussels district of Schaerbeek, Belgian police found a discarded laptop belonging to one of the suicide bombers -- a Belgian named Najim Laachraoui -- who is believed to have built the bombs used in the Paris and Brussels attacks. Although much of the hard drive had been wiped clean, weeks of painstaking digital forensic analysis by the Regional Brussels Computer Crime Unit yielded a treasure trove of new information on the ISIS network behind the November 13, 2015, Paris and March 22, 2016 Brussels attacks (which included a bombing of the city's subway system), according to Belgian investigative files obtained by CNN.After the March 22, 2016, terror attack in Brussels, police found a discarded laptopThe laptop has revealed a treasure trove of details about the ISIS network behind attacks

PROBLEM: (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

PROBLEM: The voters of the Rust Belt have shaken up the 2016 presidential campaign: Hoping to jolt a political system they see as ineffective and out of touch, they have repeatedly revolted by supporting unlikely, anti-establishment candidates. In both Donald Trump and Bernie Sanders, these voters see a potential for change they haven't felt in generations. They say they are willing to shed party allegiances and reimagine their priorities this year, even voting for a self-described democratic socialist, or for a flame-throwing real estate developer who has never served in government. In doing so, they have become the engine of one of the most extraordinary elections in modern U.S. history.CNN spent a week visiting three Rust Belt citiesVoters are fed up with the status quo and hungry for change 
 Questions:"I know a lot of people think _'s crazy," he says, "but he's different." (A) Rust Belt (B) Donald Trump (C) Bernie Sanders (D) U.S. (E) CNN
