问题 What cows constitutes high percentage in the total cows butchered each year? [br] What result did the cow that had BSE produce?

选项 A、The America’s cattle industry closed down.
B、180 000 cattle were infected and slaughtered.
C、Nearly 150 people died from this fatal disease.
D、Britain also diagnosed a case of BSE in the same time,

答案 A

解析 根据题干中的BSE可以定位到第二段第三、四句。根据这两句可知来自Sunny Dene农场的母牛是在12月9日被检验的,但是结果到22日才出来。然而,就是这个结果使美国每年二百七十亿产值的牧业,也是世界上最大的牛肉生产商冻结了。因为这只母牛被检验出得了牛绵状脑病,即为人们所知的致命的疯牛病。也就是说,这只母牛被检出得了疯牛病造成了美国牧业的停滞。根据本段最后两句可知英国在1983年发现了第一例疯牛病,这最终使得十八万头牛感染并导致将近150人死亡,十八万头牛感染是英国疯牛病的结果,故可排除B;导致将近150人死亡是英国疯牛病的结果,故可排除C;文章中并未提及英国与此同时也检出了一例疯牛病,故可排除D。
