Rabbits are not native to Australia, which lacks predators capable of keeping their numbers in check. The rabbit population, left unchecked, expands to such large numbers that it destroys large areas of pastoral land by stripping it of grass. Scientists have recently isolated a virus which has devastated rabbit populations in Central Asia and is harmless to humans. Australian farmers urge scientists to release this virus so that they can reclaim pastoral land currently lost to rabbits.
The farmers who urge the immediate release of the virus assume all of the following EXCEPT
A)the number of natural predators will not significantly increase in Australia in the near future
B)the virus will not be harmful to livestock that graze on the pastoral land
C)the virus will have the same effect on rabbits in Australia as on rabbits in central Asia
D)the release of the virus is the only means of reducing the rabbit population in Australia
E)if the rabbit population fell in Australia, land that had been damaged by rabbits would return to a state useful for farming
