### HideShow timer Statistics

A newly discovered disease is thought to be caused by a certain bacterium. However, recently released data notes that the bacterium thrives in the presence of a certain virus, implying that it is actually the virus that causes the new disease.
Which of the following pieces of evidence would most support the data’s implication?
(A) In the absence of the virus, the disease has been observed to follow infection by the bacterium.
(B) The virus has been shown to aid the growth of bacterium, a process which often leads to the onset of the disease.
(C) The virus alone has been observed in many cases of the disease.
(D) In cases where the disease does not develop, infection by the bacterium is usually preceded by infection by the virus.
(E) Onset of the disease usually follows infection by both the virus and the bacterium.

i will say c. the stem is basically providing data that shows that the virus is the root cause of the disease.

C pretty much says exactly that; if the virus alone has been observed with the disease, with no bacterium acting as middleman, then we have our supporting argument.

Agreed. The implication is that the virus is the cause of the disease not the bacterium. C clearly helps to support this.

(A) In the absence of the virus, the disease has been observed to follow infection by the bacterium. - This contradicts the conclusion, basically saying that the virus is not causing the disease - Eliminated
(B) The virus has been shown to aid the growth of bacterium, a process which often leads to the onset of the disease. - This is similar to saying virus is the catalyst for the disease, not necessarily the cause of it - Eliminated
(C) The virus alone has been observed in many cases of the disease. - The bacterium cannot be the root cause of the disease in this case - Keep
(D) In cases where the disease does not develop, infection by the bacterium is usually preceded by infection by the virus. - Irrelevant since this is about cases in which the disease has not developed - Eliminated
(E) Onset of the disease usually follows infection by both the virus and the bacterium. - The root cause cannot be determined - Eliminated
