问题     Dowes Ginting, the most wanted man on Sumatra Island, lay dying. He had abandoned the hospital where he had seen his relatives succumb one after another, and he had fled deep into the mountains, trying to outrun the black magic that he feared had marked him next. For four nights, witnesses recalled, a witch doctor hovered over him in a small clapboard home, resisting the evil spell.
    Ginting, a tough 32-year-old, had watched disease burn through his family over the previous two weeks, killing six and sickening two others, including himself. International health experts grew increasingly concerned when laboratory tests confirmed they were sickened by bird flu, the largest cluster of the disease ever recorded. But Dowes feared medical treatment more than he did the flu. And so he ran, potentially exposing villagers across the province to the highly lethal virus.
    In the end, the outbreak in May did not predict the start of a worldwide epidemic. But the enormous difficulties that Indonesian and international disease specialists confronted in investigating the outbreak and protecting against its spread raised fundamental questions about whether bird flu could be contained when it converted into a form more easily spread among people.
    "If this were a strain with sustainable transmission from human to human, I can’t imagine how many people would have died, how many lives would have been lost," said Surya Dharma, chief of communicable disease control in North Sumatra province.
    Officials from the World Health Organization, drawing on sophisticated computer modeling of a theoretical bird flu outbreak in Southeast Asia, have suggested that an epidemic could be twisted through a rapid containment effort in the affected area, including the right mix of drugs, quarantines (隔离,封锁) and other social controls. To succeed, the antiviral drug Tamiflu would have to be distributed to 90 percent of the targeted population, roughly defined as those within at least a three-mile radius of each case. The drug would have to be administered within 21 days from the "timely detection" of the initial case of an epidemic strain. Residents would have to stay home, limit contact with others and take the medicine as prescribed.
    In the case of the North Sumatra cluster, almost none of this happened, according to extensive interviews with health officers, family members and villagers in several areas of the province. The underlying problem was that most family members and many villagers were convinced that black magic not flu, was to blame.
    "How can you ever get people to cooperate if they don’t even believe you?" Dharma said.
    On the fourth night, unfortunately, Dowes took an abrupt turn for the worse. The medicine man repeated his treatment several times in the night. And before his uncle lugged him to his Suzuki SUV parked out front and set off for the district hospital, Dowes had died.
What was to blame for the spread of the disease according to the author?

选项 A、Local people’s ignorance of bird flu.
B、The delayed distribution of the drug.
C、The ineffectiveness of the given drug.
D、Health officers’ pedagogical instructions.

答案A

解析 可根据文章首尾两段判断,当地居民的不合作态度缘于他们对禽流感疾病缺乏足够的认识,他们不相信医学,所以才宁愿选择其他不合适的方法进行治疗,故A项为正确答案。
