HideShow timer Statistics

The more television children watch, the less competent they are in mathematical knowledge. More than a third of children in the United States watch television for more than five hours a day; in South Korea the figure is only 7 percent. But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concept, 40 percent of South Korea children are competent in these areas. Therefore, if Untied States children are to do well in mathematics, they must watch less television.

Which one of the following is an assumption upon which the argument depends?

(A) Children in the United States are less interested in advanced measurement and geometric concepts than are South Korea children.

(B) South Korea children are more disciplined about doing schoolwork than are children in the United States.

(C) Children who want to do well in advanced measurement and geometry will watch less than television.

(D) A child's ability in advanced measurement and geometry increases if he or she watches less than one hour of television a day.

(E) The instruction in advanced measurement and geometric concepts available to children in the United States in not substantially worse than that available to South Korea children.

(A) Children in the United States are less interested in advanced measurement and geometric concepts than are South Korea children.
- less interested is totally out of scope and doesn't really help to prove the conclusion, as we do not know how watching less television, is going to effect on children who are less interested in mathematical knowledge.

(B) South Korea children are more disciplined about doing schoolwork than are children in the United States.
- This is again out of scope. This information doesn't help us to prove the fact that watching less TV -> children will do well in maths.

(C) Children who want to do well in advanced measurement and geometry will watch less than television.
- We need to prove : watching less TV -> children will do well in maths.
So, this is just the opposite.

(D) A child's ability in advanced measurement and geometry increases if he or she watches less than one hour of television a day.
- The premise says about children who watches TV for 5 hrs. We can not prove the conclusion using this piece of information.

(E) The instruction in advanced measurement and geometric concepts available to children in the United States in not substantially worse than that available to South Korea children.
- Ok, the author here used a technique to falsify a scenario that could have hurt our conclusion.
Negating this , will hurt the conclusion.
Assuming that the students of USA and South Korea have similar potential to grasp knowledge, if the concepts available to the students of USA are not as good as that of South Korea, the conclusion may not be always true.
So, E, IMO is the correct answer.

B is a good distraction. Out of scope though, close but not close enough.
Pattern: Another way?
