问题     Cutting toxic levels of city air pollution to safer levels is simple, but not easy—it requires resolve. Yet, despite the key culprit (罪犯) in the UK being well known—diesel (柴油机的) vehicles—the government has been asleep at the wheel for years.
    Levels of nitrogen dioxide (二氧化氮) have been illegally high across much of the UK since 2010. In 2015 86% of major urban areas broke annual limits. Cutting this pollution means choking off diesel emissions and there is a wide range of effective measures available.
    Creating zones in city centres where polluting cars are either banned or charged is important, while making cities safe for cycling and walking cuts traffic too.
    Cleaner buses and taxis have an important role to play and change to the perverse taxes that encourage people to buy diesel over cleaner cars is needed. There is also some support for a revival of a scrappage scheme which saw dirty old bangers taken off the road.
    The environment and transport departments were well aware of all this and proposed many of these measures internally, only for the Treasury to reject most of them, arguing they "would be politically very difficult, especially given the impacts on motorists".
    Motorists happen to be particularly badly exposed to air pollution, but the real political difficulty for the government is two humiliating legal defeats in two years where judges ruled its air pollution plans were so bad they were illegal.
    Ministers have now been forced to come up with a third plan, but clean air zones and car tax changes take time to clean up the air. Yet the UK government is also in the slow lane when it comes to emergency measures.
    When foul air descended on Paris in December, officials there swung into action. Public transport was made free and the number of cars allowed on roads was restricted, alternately barring those with odd and even licence plates. In the UK, during the same December smog, the government sent a few tweets.
    At the root of the problem are diesel cars, which successive governments across Europe have utterly failed to ensure meet legal emissions limits when driving in real-world conditions on the road. The gaming of regulatory tests by carmakers was blown open by the Volkswagen scandal. The scandal of governments prioritising supposed driver freedom over the lungs and health of their citizens is only now playing out.
The aim of those in favor of a scrappage scheme is________.
选项 A、to reduce diesel emissions
B、to encourage the use of old cars
C、to retire low-end old vehicles
D、to cut down on traffic accidents
答案A
解析 推理判断题。第二段最后一句提到，减少这种污染意味着要遏制柴油机的排放，这可采取多项有效措施。这是一个承上启下的句子，概括了第三段和第四段的主要内容。第四段最后一句指出，还有一些人支持恢复实施旧车报废计划，该计划曾见证了污染严重的老旧车辆被淘汰。由此可知，旧车报废计划也是措施之一，这些人支持旧车报废计划的目的是为了淘汰污染严重的老旧车辆，从而遏制柴油车的排放，故答案为A)。B)“为了鼓励使用旧车”和C)“为了淘汰低端旧车”与第四段最后一句的表述不符，故均排除；D)“为了减少交通事故”，原文并未提及交通事故，故排除。
