A team of German scientists recently concluded a ten year study on the relationship between red or white meat consumption and the risk of intestinal cancer; the study revealed that those who ate on average more than one serving per week of red meat had 44 percent less risk for developing Adenocarcinoma, the most common form of intestinal cancer.
Though all previous studies on the relationship between red meat and the prevalence of intestinal cancer have been inconclusive, the German scientists attribute the lower rate of intestinal cancer to increased intake of myoglobin.
White meat is rarely rich in myoglobin, and those in the study who ate white meat had the same risk for developing Adenocarcinoma as those who ate no meat at all.
In the statement above, the two portions in boldface play which of the following roles?
A.The first is an opinion that is supported by the argument; the second is one part of the information uncovered in the study.
B.The first presents the quandary the scientists are attempting to solve; the second is the result of that quandary.
C.The first is a fact that goes against the argument that is being presented; the second is one element of a logical argument in support of the scientists claim.
D.The first is a claim in support of the argument; the second is a piece of evidence against the argument.
E.The first is an explanation advocated by the argument; the second is a finding used to challenge that explanation.

The first boldface portion:
“Though all previous studies on the relationship between red meat and the prevalence of intestinal cancer have been inconclusive,”
This sets up the explanation that past attempts to link red meat to intestinal cancer have not been successful or have failed to deliver definite results. It essentially provides the background or an explanation that guides the argument being discussed.
The second boldface portion:
“White meat is rarely rich in myoglobin,”
This fact is presented as a finding that challenges the explanation above. The original claim is that myoglobin intake may explain the cancer risk difference, but since white meat is low in myoglobin and study participants eating white meat had the same cancer risk as those eating no meat at all, the new information undermines or challenges the initial suggested explanation about myoglobin and cancer risk.
Analysis of Options:
• A: Incorrect. The first isn’t just an opinion; it summarizes inconclusive findings of previous research. The second is a result but it doesn’t support the primary argument outright.
• B: Misleading because it treats both bold portions as a problem and its direct result, which doesn’t match the text structure.
• C: Wrong. The first is not a fact against the argument, but context about prior studies being inconclusive.
• D: Incorrect. The second is not evidence directly against an argument but rather it undermines the explanation offered for risk, making the relationship more complicated.
• E: Accurate. The first statement gives the explanation; the second offers a finding that challenges it.
The answer objectively fits because it is the only option where each bolded portion’s role precisely matches how the passage frames them in argument structure and scientific reasoning. It accepts that explanations and challenges are both common components in research reporting, making this pairing the most logically sound.
