Article: My daughter recently asked me what a Travel Agency does. There is one located on our street and it has just been completely rebuilt. I told her that they helped people book their trips and vacations. "Why haven't we ever been in there?" she wanted to know. "Because we do everything ourselves online these days" I explained. "But why do it yourself if other people want to do it for you?" she wondered out loud. The answer is that the travel agency makes a little bit of money on each ticket you book through them. If you book your ticket yourself, online, you save that money. Saving money sounds great except that when you think about it you typically spend three evenings comparing prices to end up saving $30 on a $300 trip. All those $30 discounts add up of course so I guess we should be happy with that. Still, how bad is it really to pay someone $30 and trust them to buy you something decent? Wouldn't you say your free evenings are worth more than $10 a piece? Consider books for a moment. Buying your book at Amazon saves you maybe 30% to 40% on each book. Add to that the convenience of shopping from home and getting the package delivered to your home address. So far so good. Unfortunately that does mean you spend way too much time browsing Amazon. com while you could do something fun instead. Like maybe reading an actual book? Then the package arrives and you aren't home and end up having to pick it up at the local post- office. All in all I wonder how much time I end up investing in the whole process. Time sounds free, but to most of us, it is more valuable than money. The Internet Economy promised to get rid of the middle-men and we loved it. Somehow, I'm starting to get the feeling that we ourselves ended up doing the work of that middle-men we were so eager to get rid of. In any project you can always pick two of these: fast, cheap or good. We seem to have focused a lot on 'cheap' and 'good' but the extra time we need to invest to keep it 'fast' comes out of our own pockets. You can always make more money but you can never make more time.
Question: What's the author's attitude towards the Internet Economy?
Options: (A) The author thinks online shopping saves time and is a convenient way to buy products. (B) The author worries about sending personal information over the internet. (C) The author doesn't think online shopping is satisfactory in every way. (D) The author likes the convenience but is concerned about the e-commerce environment.

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
