Question

https://gmatclub.com/forum/download/file.php?id=84444 Patterns in Strengthen the Conclusion Above is an excerpt from the chapter Strengthen the Conclusion in our book EducationAisle Critical Reasoning Nirvana : Having covered the various patterns in our previous posts, let us see how skilled you are at applying these patterns, to the question below: ------------------------------------------------------------------------------------------------------------------------------------------------------------- There is a great deal of geographical variation in the frequency of diabetes—almost 10% of the adult population in China suffers from diabetes compared with just 2.6% in countries such as Ukraine To support a conclusion that much of the variation is due to the high-sugar diets of the Chinese, it would be most important to establish which of the following? (A) People in China seek preventive medical examination, leading to incidence of diabetes being detected at an earlier stage. (B) The variation is unrelated to factors (other than the amount of sugar in the diet) that influence the incidence of diabetes. (C) While incidents of type-1 diabetes are higher in China, the incidence of type-2 diabetes are lower than in most countries. (D) For certain types of diabetes, it is difficult to pinpoint the exact cause of the disease. (E) Despite a higher incidence of diabetes in China, people there have a higher life expectancy than in most other countries with a lower incidence of diabetes GMAT-Club-Forum-a2q6p6p0.png

EducationAisle · Answer

Indeed. Kudos to you.

Here is the detailed explanation:

The argument presents the following information:

Almost 10% of the adult population in China suffers from diabetes compared with just 2.6% in countries such as Ukraine.

The Conclusion that we have to support is: Consumption of high-sugar diets by the Chinese is the reason for the high incidence of diabetes the adult population in China.

A. This answer choice actually suggests an alternate cause for the high incidence of diabetes the adult population in China: people in China seek preventive medical examination. So, this answer choice suggests that the incidence of diabetes is low in countries such as Ukraine perhaps because a lot of people who do have diabetes in such countries, are actually not aware that they have diabetes (since they do not seek preventive medical examination, as opposed to people in China).

B. This answer choice, very succinctly, eliminates all alternate causes for the significant geographical variation in the frequency of diabetes. It states that apart from the amount of sugar in the diet, no other factor (such as genetics or more proactive preventive medical examination) is responsible for the significant geographical variation in the frequency of diabetes. Correct.

C. Knowing the different types of diabetes (such as type-1 and type-2) does nothing to support our conclusion. This is because diabetes referred to in the argument is clearly referring to all types of diabetes and hence, breaking diabetes into type-1 and type-2 does not provide any additional information. Incorrect.

D. This answer choice suggests that for certain types of diabetes, it is difficult to find the root cause of the disease. If we cannot confidently determine the cause, we cannot support the cause that consumption of high-sugar diets by the Chinese is the reason for the high incidence of diabetes the adult population in China. Incorrect.

E. This answer choice basically suggests that diabetes is not bad news! However, neither the argument nor the question stem requires us to explore the effects of diabetes. Hence, this answer choice does nothing to support the conclusion of the argument. Incorrect.
