单选题{{B}}Passage Four{{/B}} Diego Chiapello, legally blind since birth, isn't one of Italy's famous "mama's boys" who live with their parents into adulthood. The 27-year-old lives alone in Milan, works as a network administrator, loves diving and dreams of sailing across the Atlantic with a sight-impaired (有视力障碍的) crew. Obviously, he's not your average disabled person--but especially so in Italy. The country has more barriers to integration than almost anywhere else on the continent. Among European countries, Italy ranks third from the bottom in accessibility for the disabled, ahead of only Greece and Portugal. People who use wheelchairs, especially, find it difficult to navigate the country's cobblestone (鹅卵石) streets, ride buses or visit restaurants, shops and museums. Less than a quarter of Italy's disabled hold jobs compared with 47 percent for Europe. But the biggest obstacle for the country's physically challenged may, in fact, be the fabled Italian family. Because of the social defect that still attaches to disabilities, "they tend to keep disabled people at home and out of public view," explains Giovanni Marri, head of an employment training center in Milan that caters to the handicapped. Thus while 15 percent of the country's families include a disabled person, according to surveys, only 2 percent of Italians report going to school with a disabled person and only 4 percent work with one. Italians are beginning to recognize the problem. Over the past decade, the government has passed laws targeting everything from workplace discrimination to accessibility requirements. A recent study by the European Union found that 85 percent of Italians admit that public transportation and infrastructure (基础设施) are inadequate for the handicapped, and 97 percent say action is needed. But the biggest barrier is psychological. "Italian companies are afraid of hiring disabled people," says Chiapello. The only way to alter that, he says, is for Italy's disabled to do 'what he did--get out of the house and demand change.

单选题Women have been driving yellow cabs in New York since the 1940s, but 99% of drivers are male. Even among drivers of cars booked by phone or online, only 4% are women. That may change with the launch of SheTaxis, an app that lets female passengers insist on female drivers, and vice versa. It will be available in New York City, Westchester and Long Island, and the firm plans to expand to other cities. Stella Mateo, the founder, is betting that quite a few women are nervous and weary of getting into cars driven by men. The service may also appeal to those whose religious beliefs forbid them to travel with unrelated men. Each driver wears a pink pashmina. Men who ask for a ride will be directed to another car service. Similar services thrive in India, South Africa and several Middle Eastern cities. Japan has had women-only railway carriages on and off since 1912. Known as hana densha (flower trains), they offer shelter from the gropers who make rush hour in Tokyo so disagreeable. But SheTaxis faces two speed bumps. One is practical. Demand has been so great that the firm has had to decelerate its launch until it can recruit 500 drivers. The other obstacle is legal. By employing only female drivers, SheTaxis is obviously discriminating against men. Since anti-discrimination law is not always applied with common sense, that may be illegal. And there is no shortage of potential litigants. Yellow cabbies are furious at the growth of online taxi firms such as Uber. "It"s not hard to imagine a guy ... filing suit," says Sylvia Law of New York University Law School. "SheTaxis" defence would probably be that its drivers are all independent contractors." Because the firm caters only to women, it is discriminating against male customers, too. Is that legal? Angela Cornell of Cornell Law School thinks there could be a loophole. New York"s Human Rights Commission could make an exemption on the ground that SheTaxi offers a service that is in the public interest: women feel safer not getting into cars with strange men. Women-only colleges are allowed, so why not women-only cabs? The snag is that some men may also feel safer getting into cabs with female drivers. A study in 2010 found that 80% of crashes in New York City that kill or seriously injure pedestrians involve male drivers. Women drivers are simply better.
