GRE写作argument全部官方范文分析(12)

　　Even assuming the correlation between high iron levels and heart disease is existed, the conclusion that such correlation serve as a function of the correlation between red meat and heart disease, is logically flawed. The writer makes an assumption that the red meat, which contains iron as claimed, is equal to any diet contained iron, like the one that respondents have. Perhaps this is not the case. Common sense informs us that, in terms of the function and the effect, iron involved in different compounds or just the element is quite diverged. Is the iron in red meat exists as the form such as compound very different from just the element of iron? If so, a survey to research this particular form of iron in the red meat and its correlation with heart disease is necessary.

　　Besides iron, other elements or compounds in the red meat could also have a impact on the respondents. It is critical to clear that how many compounds and elements exist in the red meat, and most importantly, how they function. Even a fine quantity of these, could impact on the respondents. It is possible that one or several non-iron compounds or elements in the red meat caused the heart disease. Also, it is entirely possible that, the way they cook and the container of the red meat, lead to heart disease. That is to say, maybe there are some heart-disease-related elements on the inside surface of the container, and it is cooked so thoroughly for a long time that these elements have taken off from the container and immerged to the red meat. In that case, the increased risk of heart disease may ascribe to these, other than iron.
