When is cleaning walls a crime? When you’re doing it to create art, obviously. A number of street artists around the world have started expressing themselves through a practice known as reverse graffiti (涂鸦). They find dirty surfaces and paint them with images or messages using cleaning brushes or pressure hoses (高压水管). Either way, it’s the same principle: the image is made by cleaning away the dirt. Each artist has their own individual style but all artists share a common aim: to draw attention to the pollution in our cities. The UK’s Paul Curtis, better known as Moose, operates around Leeds and London and has been commissioned by a number of companies to make reverse graffiti advertisements.

        Brazilian artist, Alexandre Orion, turned one of Sao Paulo’s transport tunnels into an amazing wall painting in 2006 by getting rid of the dirt. Made up of a series of white skulls (颅骨), the painting reminds drivers of the effect their pollution is having on the planet. “Every motorist sits in the comfort of their car, but they don’t give any consideration to the price their comfort has for the environment and consequently for themselves,” says Orion.

        The anti-pollution message of the reverse graffiti artists confuses city authorities since the main argument against graffiti is that it spoils the appearance of both types of property: public and private. This was what Leeds City Council said about Moose’s work: “Leeds residents want to live in clean and attractive neighborhoods. We view this kind of advertising as environmental damage and will take strong action against it.” Moose was ordered to “clean up his act”. How was he supposed to do this: by making all property he had cleaned dirty again?

        As for the Brazilian artist’s work, the authorities were annoyed but could find nothing to charge him with. They had no other option but to clean the tunnel—but only the parts Alexandre had already cleaned. The artist merely continued his campaign on the other side. The city officials then decided to take drastic action. They not only cleaned the whole tunnel but every tunnel in Sao Paulo.

解析：B。根据题干中的Brazilian artist Alexandre Orion可定位至第二段首句。该句说到，2006年，巴西艺术家亚历山大·奥里恩通过清理污垢，在圣保罗的一条交通隧道里打造出了一幅令人惊叹的壁画。B项内容与原文表述一致，tunnels为原词复现，his graffiti art是定位句中wall painting的同义替换，故正确答案为B。

错项排除：A项利用原文词painting和white skulls作干扰，但原文说的是奥里恩在隧道里的画作是由一系列白色的颅骨图案组成，并没有说他是否擅长画白色头骨，故A项错误。C项用原文出现的pollution和car作干扰，但原文说的是奥里恩的画作旨在警示司机汽车对环境所造成的的污染，并没有建议要禁用所有污染环境的汽车，banning和all在文中没有依据，故C项排除。原文中没有提到奥里恩是否喜欢制作有创意的艺术品，was fond of在文中没有依据，D项属于无中生有，故排除。
