Article: With more and more wineries offering organic varieties to lower their eco-footprint , it's no surprise that they're looking at the environmental impacts of their packaging as well. The making of conventional glass bottles and the corks uses large quantities of natural resources and causes a lot of pollution. Beyond manufacturing, the transport of wine in glass bottles across the country and around the world also has its environmental effect. Trucking all the heavy glass bottles causes a much larger carbon footprint than the transportation of much lighter boxed wine. Almost half the weight of an ordinary case of wine comes from the bottles; about 95 percent of the weight of a case of boxed wine is the wine itself. "A standard wine bottle holds 750 milliliters of wine and causes about 5.2 pounds of carbon dioxide when it travels from a farm in California to a store in New York," reports Colman, a researcher. "A 3-liter box causes about half the carbon dioxide per 750 milliliters." According to the Wine Group, the third largest wine company in the world and a big advocate for switching away from glass bottles, there are other advantages to boxed wine (which typically includes a plastic bag within a cardboard box). The vacuum packaging of boxed wine allows it to stay fresh for up to six weeks in the fridge once the seal is broken and the first glass has been poured. Still, despite the benefits, boxed wine may still be a tough pill to swallow for many wine experts. "Even those traditionalists who are coming around to the idea that maybe screw caps are fine for some wines, would not like the idea of a cellar full of cardboard boxes," says wine writer Lee Asbell. "It is difficult to imagine how wine service at fine-dining establishments would handle such a change." For now, boxed wine is still the field of cheaper brands. But that could all change as more and more wine makers and drinkers take responsibility for saving the Earth.

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: Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer-Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the several hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left fourteen One Penny Orange-Reds and twelve Two Penny Blues. Because of the Two Penny Blue's rareness and age, collectors have paid as much as $16 800 for it.
