Q29:
Lofgren’s disease has been observed frequently in commercially raised cattle but very rarely in chickens. Both cattle and chickens raised for meat are often fed the type of feed that transmits the virus that causes the disease. Animals infected with the virus take more than a year to develop symptoms of Lofgren’s disease, however, and chickens commercially raised for meat, unlike cattle, are generally brought to market during their first year of life.
Which of the following is most strongly supported by the information provided?
The feed that chickens and cattle are fed is probably not the only source of the virus that causes Lofgren’s disease.
想不明白B,C有什么区别,谢谢拉

看逻辑链:牛和鸡都吃带病毒的东西---这个病1年后发病,而鸡1年不道就杀了---牛得病;鸡不得。

问:能得出什么。 逻辑链很清楚,因为鸡1年不到就杀了,所以说鸡不得病(这本身是有缺陷得,因为鸡没到发病期就被杀了)
