Article: International teams have spent nearly half a year looking for evidence of the missing Malaysian Airlines plane, a search that includes the hunt for the aircraft's so-called black box, which holds flight data that would likely explain what caused MH370 to move away from its course. But many aviation experts wonder why, in our increasingly networked world, divers are searching the Indian Ocean for a metal box when technology already exists that would enable planes to stream black box data to the ground in the event of an emergency. Black boxes have been on planes since the late 1950s, and now every commercial aircraft has two: a flight data recorder and a voice recorder. (Although they are referred to as black boxes, they are typically orange in color, making them easier to spot in waters.) Black box recorders are mainly used to investigate the cause of in-flight accidents. While black boxes are built to survive a crash and long-term submersion in water, it can be a real challenge to find the device if a plane has gone down in the ocean. While each box contains a beacon , the unit only has enough battery power to transmit a signal for 30 days. After the crash of Air France Flight 447 in the Atlantic Ocean in June 2009, it took divers two years to find the black box. Pierre Jeanniot, a Canadian engineer who helped perfect black box technology about 40 years ago, feels that the device, in its current form, is " _ ". He started to question its effectiveness more than a decade ago, after seeing the broken pieces of the black boxes in the 2001 attacks on the World Trade towers in New York. Jeanniot is now on the advisory board of a Toronto-based firm that has built a live-streamed black box system. When a plane experiences an irregular event, the system can send streaming data off the aircraft to one of the satellites and then down to ground-based servers, where the message is interpreted and sent to the airline. It seems necessary that the loss of MH370 and other similar cases wake more people up to the fact that the tools being used at this stage are inadequate for dealing with emergency situations, Jeanniot says. He also estimates that if this technology had been on board the missing Malaysian Airlines flight and live-streaming for the estimated seven hours after the flight first experienced a problem, it would have cost about $3,000. While there is widespread approval of a live-streamed black box system, most airlines see its cost prohibitive. The airline industry is an industry with small profits, and is reluctant to add costs that will further cut the bottom line. However, given how much time, money and effort has been spent on the luckless search for MH370, s black box, the cost of operating a live-streaming version seems like a trifle
Question: Which fact is mentioned to support aviation experts' doubt about the effectiveness of the black box?
Options: (A) MH370's black box holds flight data that might explain what happened to the aircraft. (B) The recorders are actually orange in color though referred to as black boxes. (C) The beacon in the black box has limited battery power to send out a signal for 30 days. (D) It's necessary for people to wake up to the weaknesses of the black box

Article: A popular CCTV host's "improper remarks" that were caught on video at a dinner party have led to an investigation into the incident and a suspension of his programs. The video, released online on Monday, showed host Bi Fujian using vulgar words about Chairman Mao Zedong while singing in the style of Peking Opera, enraging some netizens and causing a stir on the Internet. CCTV said on its micro blog on Wednesday that it will investigate the incident, which it said many have found disturbing. Bi's programs will stop being broadcast until at least Sunday, as his comments in the video have seriously damaged the broadcaster's image, Huaxi Metropolis Daily quoted a CCTV staff member as saying. The CCTV employee said it is uncertain whether the programs can be broadcast again after Sunday, the report added. Bi, 56, is popular for a hosting style that engages the audience. He has hosted the CCTV Spring Festival Gala since 2012, as well as a popular talent show involving Westerners speaking Chinese. The cancellation was the first decision after Nie Chenxi was named CCTV president on Tuesday, the report said, adding that Nie had ordered all staff members to strictly correct work styles. A micro-blogger named Zhou Junchi said that free speech doesn't mean it is OK to defame others, adding that Bi's comments were not proper for a popular host. Cheng Manli, a professor specializing in communication at Peking University, echoed Zhou, saying Bi should pay more attention to his behavior and speech as a public figure. "It does not mean we cannot share our opinions, but using ugly words and sarcasm to comment on Chinese leaders who have passed away is improper," Cheng said. "The actions and words of celebrities are easily broadened in today's Internet era, which is open and can have a huge influence, so it is a must for the public figures to _ the quality of their speech and behavior. Otherwise, their images will be affected, such as the stars who were recently punished for drug use," she said. "Everyone should take responsibility for what he or she says in public and online. It's better, I think, to share different ideas in a normal way," she suggested. But she added that the party in the video seemed private, "so its release is also improper to some extent." The video was recorded by someone sitting on Bi's right, but who it is and why the video was put online is unknown.
Question: According to the passage, CCTV's response when the incident happened was _ .
Options: (A) to change his job (B) to have Bi Fujian fired (C) to look into the matter (D) to make him apologize
Asnwer: C
