Q: (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

Q: (CNN) The 10-minute conversation between US President-elect Donald Trump and Taiwan President Tsai Ing-wen was a major break in the accepted protocol -- something that evidently does not much bother Mr. Trump. It is, of course, too soon to guess whether it was a fluke or a portent of a sea change in American policy. When the Communists won power on the mainland in 1949 their defeated Nationalist foes retreated to the island of Taiwan, either to go down in a last stand or to "recover the mainland." The Communists, for their part, determined to "liberate Taiwan." Both sides considered the standoff to be part of a continued civil war. Both claimed legitimate rule over all of China, with Taiwan merely a province of China. The one thing both agreed on was that Taiwan was inextricably part of China, and was not and could not be an independent country.Donald Trump's phone call with Taiwan was a major break in protocol, writes Peter MoodyMoody: It is too soon to say whether it means a sea change in US policy 
 Questions:Danger of communist subversion served to rationalize the dictatorship, although in practice the repression was directed at least as much against agitation for _ independence. (A) US (B) Donald Trump (C) Taiwan (D) Tsai Ing (E) Trump (F) American (G) Communists (H) Nationalist (I) China (J) Peter Moody (K) Moody
