问题                         Reduce Waste-Food
    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 pro-gram. 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 bags and given to the city to use as compost. 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. 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.
What is the main reason for people paying attention to food waste?
选项 A、To lower the cost of food waste.
B、To save more food for the world.
C、To keep the dining room clean.
D、To reduce the effort of cooking.
答案A
解析 事实细节题。由题干中的food waste定位到第一段。第一段第二句说：饭店、学校、医院和其他机构正在通过新颖的方式来减少高额的垃圾处理带来的费用。而且在文章后面的部分也不止一次地提到了金钱。所以最主要的原因是[A]“减少食品浪费所带来的费用”。
