A study found that last year roughly 6,700 homeless people in the United States were admitted to hospitals due to malnutrition. In the same year, a little more than 7,200 nonhomeless people were admitted to hospitals for the same reason. These findings clearly show that the nonhomeless are more likely to suffer from malnutrition than are the homeless.
The answer to which of the following questions would be most likely to point out the illogical nature of the conclusion drawn above?

(A) What is the relative level of severity of the malnutrition suffered by each group cited in the study?

(B) To what extent, on average, are the nonhomeless better off financially than are the homeless?

(C) To what extent are the causes of malnutrition in the nonhomeless related to ignorance of proper dietary habits?

(D) What percentage of each group cited in the study suffered from malnutrition last year?

(E) What effect would a large increase in the number of homeless shelters have on the incidence of malnutrition among the homeless?

In this argument, we are given the number of people who were admitted into hospital due to malnutrition.
Around 6700 homeless people were admitted compared to the 7200 non-homeless people and a conclusion
is drawn that non-homeless are more likely to suffer from malnutrition than are the homeless. We have been
asked to point out a flaw in the reasoning.

Option D(What percentage of each group cited in the study suffered from malnutrition last year?) clearly
addresses this issue and is our answer!

do not worry much, just try to solve more verbal questions, and skim the solution. I suggest you borrow the book "Official Guideline" from the library and go to wiley.gmat website. It has free question banks.

Back to this question, there are 2 groups: homeless people and none-homeless people.

hello, whenever you see an evaluate question, that question is an assumption question. One technique is to try to answer each question in the option. Another way is to find the gap. The third technique is to build up the argument structure from the passage and find the logical issue. Here, I use the third technique. Each of 3 methods has the pre-thinking technique.
Noting that the argument tries to discuss the percentage, then test takers should think of the flaw about the number or the amount (pre-thinking technique)

D is the answer.

The answer is D - the argument considered a numerical value to carry the same weight as a percentage.

A study found that last year roughly 6,700 homeless people in the United States were admitted to hospitals due to malnutrition. In the same year, a little more than 7,200 nonhomeless people were admitted to hospitals for the same reason. These findings clearly show that the nonhomeless are more likely to suffer from malnutrition than are the homeless.
The answer to which of the following questions would be most likely to point out the illogical nature of the conclusion drawn above?

(A) What is the relative level of severity of the malnutrition suffered by each group cited in the study?
Severity of malnutrition is out of scope. If people are suffering from malnutrition then they are suffering from malnutrition.

(B) To what extent, on average, are the nonhomeless better off financially than are the homeless?
Financially? Out of scope

(C) To what extent are the causes of malnutrition in the nonhomeless related to ignorance of proper dietary habits?
ignorance of proper dietry habits? Out of scope

(D) What percentage of each group cited in the study suffered from malnutrition last year?
Correct. If the homeless who suffered malnutrition were 90% of the total homeless people and the non-homeless who suffered from malnutrition were only 20% then this option casts doubt on the argument. Correct.

(E) What effect would a large increase in the number of homeless shelters have on the incidence of malnutrition among the homeless?
This option talks about a scenario that might occur in the future - a hypothesis. This option is out of scope.
