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?
A.The virus that causes Lofgren’s disease cannot be transmitted to human
beings by chickens.
B.There is no way to determine whether a chicken is infected with the Lofgren
s disease virus before the chicken shows symptoms of the disease.
C.A failure to observe Lofgren’s disease in commercial chicken populations
is not good evidence that chickens are immune to the virus that causes this
disease.
答案是C。我想請問一下A選項是哪裡不對?
另外想請問B選項的錯誤之處是否是在there is no way 有過度推論之嫌?
懇請大家幫忙解惑，謝謝!
