A deadly virus that has claimed the lives of local villagers has been traced to the spotted fruit bat, in which the virus resides between periodic outbreaks. Biologists speculate that the bat might also be one of the reservoirs for a number of other viruses that have led to village fatalities. The local government has proposed to eliminate the spotted fruit bat by cutting off passageways that allow the bat to emerge from its caves. Once the bat is unable to emerge from the caves, the government will have achieved its objective of reducing the number of village deaths attributable to viruses.

Which of the following, if true, would best indicate that the government's plan will not lead to its objective?

【选项】Another species of bat has been observed feeding on small animals, and has also been reported to have bitten human beings, who report feeling severely weakened after awakening from the attack.
