    Experts in the food industry are thinking a lot about trash these days. Restaurants, colleges, hospitals and other institutions are compensating for the rising costs of waste in novel ways. Some are tracking their trash with software systems, making food in smaller amount or trying to cut down on trash-hauling costs. Roughly 30 percent of food in the United States goes to waste, costing some $48 billion annually, according to a Stockholm International Water Institute study. A 2004 University of Arizona study estimated that 40 to 50 percent of food in the United States is wasted. Freshman students at Virginia Tech were surprised this year when they entered two of the campus’s biggest dining hails to find there were no cafeteria trays. Getting rid of trays has cut food waste by 38 percent at the cafeterias, said Denny Cochrane, manager of Virginia Tech’s sustainability program. Before the program began, students often grabbed whatever looked good at the canteen, only to find at the table that their eyes were bigger than their stomachs, he said
    That same phenomenon often happens at Oregon’s Portland International Airport. Busy travelers often discard half-eaten meals into trash cans, adding dozens of tons of waste that the airport must pay the city to haul away. Now the airport is carrying out a program to install food-only trash carts. The food waste is collected in biodegradable (可生物 降解的) bags and given to the city to use as compost (肥料). Besides being environmentally friendly, the changes may save the airport money. It costs about $82 to have one ton of trash hauled from the airport to the city landfill (垃圾掩埋场). But food waste costs about $ 48 a ton to haul.
    Cutting back on the waste can require spending money on software and training. LeanPath, based in Portland, Ore. , sells a software system to track food being thrown out. Steve Peterson, head chef at the MGM Grand hotel in Las Vegas, said he was surprised when he installed the LeanPath system and saw the value of food that was going out the back door. To cut costs, Peterson decided to reduce serving sizes. He said customers weren’t bothered by the switch, which has helped him lower food waste by between 15 to 20 percent over 18 months.
In which way can software help reduce the food waste?
选项 A、It can store varieties of measures from which people can choose.
B、It can help people to be always informed of the food waste.
C、It can calculate the total amount of the food offered.
D、It can connect the food needed with the data of customers.
答案B
解析 事实细节题。由题干中的software定位到第四段。本段说当运用软件时，人们可以知道食品垃圾的信息和数据，从而可以做出决定。所以[B]“保持对食品废物情况的了解”为正确答案。文章没有提到软件中是否存储有解决方案，故排除[A]；没有说是软件帮助计算总共提供的食物数量，所以排除[C]；文章没有提到软件中有顾客的信息，所以排除[D]。
