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 for Britain'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 of Europe, and pilot schemes are now under way in many British cities.
A realistic target for recycling mixed refuse is somewhere between 15 and 25 percent by weight, according to researchers at the Department of Trade and Industry's Laboratory. Statistics compiled by researchers at the University of East Anglia show that Britain could almost halve(减半)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 an 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.
Which of the following can serve as a proper title for the passage?
A.An Impossible Target

听力原文: The world has become a noisier place, say experts at the Library of Natural Sounds in Ithaca, New York. The library has the world's largest collection of natural sound recordings---including the sound of birds, frogs, and mammals. The recordings are used for scientific study, field guides, and even some movie background sounds. Finding quiet areas for recording is becoming difficult, says Greg Budney, head of the library. Even in sparsely populated areas, animal sounds can be submerged by moving trucks, highway traffic, or aircraft. Obtaining a clean recording of an animal may take days or even years, and a habitat recording of all the species in an area is virtually impossible. Animals are having trouble heating each other in loud noises as well. A report from the British Ecological Society claims that, because of noise from nearby British roadways, some birds are having trouble attracting mates and staking out their territories.
