【单选题】By 2010, half the recoverable material inBritain’s dustbins will be recycled—that, at least, was the target set byChris Patten, Secretary of State for theEnvironment.But he gave no clues as to howBritain should go about achieving it. While recycling enthusiasts debate the relative merits of different collection systems, it will largely be new technology, and the opening up of new markets, that makes Patten’s target attainable: a recycling scheme is successful only if manufacturers use the recovered materials in new products that people want to buy.
The first question is how best to separate clean element—glass containers, plastics, and some paper and metal containers that is relatively clean when discarded—from mixed refuse. This clean element is the main target forBritain’s recyclers. The method of collection is important because manufacturers will not reuse collected material unless it is clean and available in sufficient quantities.A、bewildering assortment of different collection schemes operates in the rest ofEurope, and pilot schemes are now under way in manyBritish cities.
A、realistic target for recycling mixed refuse is somewhere between 15 and 25 percent by weight, according to researchers at theDepartment of Trade and Industry’s Laboratory. Statistics compiled by researchers at the University ofEastAnglia show thatBritain could almost halve the total weight of domestic waste going to landfill by a combination of "collect” schemes(such as doorstep collections for newspapers),"bring” schemes(such as bottle banks)and plants for extracting metals.
This estimate makes two important assumptions. One is that the government will bring in legislation to encourage the creation, of markets for products made from recycled materials, especially glass, paper and plastics. The other is that industry will continue to introduce new technology that will improve both the products and the techniques used to separate recoverable materials from mixed refuse.
What does the word "assortment” (Line 5,ParA．2)probably meanA、differenceB、separation
C、classificationD、mixture

网考网参考答案：D
网考网解析：
根据原文第二段末“在欧洲人们利用不同的收集方法回收利用，而在英国实验计划正在进行”，原文中的“A bewildering assortment of different collection schemes”就是指的不同回收利用方法的混合掺杂，所以D项“mixture”正确。A项“difference”如果放入句中，就与“different”相重复，故排除；B项“separation”表示“分离”，C项“classification”表示“分类”，这两项与句意都不相符合，因此排除。故选D。 document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
