The Environment Protection Agency (EPA) is rigorously working on eradicating the Hemlock Woolly Adelgid (HWA) fungi that has damaged hemlock trees on the east coast of the country. In addition to other steps to eradicate the fungi, the EPA has conducted awareness sessions for hemlock growers on the extent of damage that HWA can cause and given the growers detailed instructions on how to identify and destroy the fungi.
Which of the following, if true, would provide the most support for the prediction that the EPA’s action will have its intended effect?
A. Some fungal infestations on pine trees closely resemble the HWA fungi.
B. Reports have shown that the HWA also affects another plant species known as the bleeding hearts, a species that is commercially cultivated by hemlock growers in the same area as hemlocks.
C. The eradication of HWA is likely to cause a serious imbalance in the ecosystem of the east coast area.
D. Hemlock trees have also been considerably damaged by the fungus E. Coli, which is native to the east coast area and attacks trees through their roots.
E. Some sub-species of hemlock trees can resist fungal infestations without human intervention.
