This is from a popular source so there would be some

This is from a popular source so there would be some "straight X" , "Give me Y" answers but let's see who explains this best ...
Math education in this country does a disservice to our children. In the lower grades, it should focus on the basic skills that students will need in higher grades to develop the ability to solve complex problems. Learning basic math skills is like learning the scales and chords that one will later use to master complicated concertos and symphonies. However, math educators in this country seem to have it backward, emphasizing in higher grades the same narrow, skillsbased approach that students learned in lower grades rather than the analytical tools they will need to solve complex math problems.
Which of the following, if true, would most seriously weaken the conclusion drawn above?
(A) While music is common in elementary school curriculums, it is rarely taught in high school.
(B) On international tests of math skills, highschool students in this country performed no worse than did their counterparts from countries where problemsolving is emphasized in higher grades.
(C) When presented with a math problem to solve, students in higher grades are more likely to arrive at different answers than students in lowers grades are.
(D) Older students tend to receive higher grades in math than do younger students.
(E) Universities in this country report a steady increase in the percentage of native firstyear students who qualify to take advanced mathematics courses such as calculus.

According to the passage, math education in this country does a disservice to the children because it does not follow the authorâ€™s â€œpreferred approachâ€

Conclusion:
"math educators in this country seem to have it backward, emphasizing in higher grades the same narrow, skillsbased approach that students learned in lower grades rather than the analytical tools they will need to solve complex math problems. "
Which of the following, if true, would most seriously weaken the conclusion drawn above?
(A) While music is common in elementary school curriculums, it is rarely taught in high school.
>>>out of scope
(B) On international tests of math skills, highschool students in this country performed no worse than did their counterparts from countries where problemsolving is emphasized in higher grades.
>>>Weakens
(C) When presented with a math problem to solve, students in higher grades are more likely to arrive at different answers than students in lowers grades are.
>>>Does not weaken or strengthen
(D) Older students tend to receive higher grades in math than do younger students.
>>>Strengthen
(E) Universities in this country report a steady increase in the percentage of native firstyear students who qualify to take advanced mathematics courses such as calculus.
>>>weakens
Between B and E, I choose B because it is more in context with the conclusion drawn esp:emphasis in problem solving in lower and higher grades

I like E though.
A C D are certainly out of scope.
I feel B is not as strong as E is.

I will go with E too
(A) While music is common in elementary school curriculums, it is rarely taught in high school.
not relevant
(B) On international tests of math skills, highschool students in this country performed no worse than did their counterparts from countries where problemsolving is emphasized in higher grades.
International test of math skills  donâ€™t know this test is of basic maths skills or complex problems â€¦ this para is about learning the skill to solve complex problems
(C) When presented with a math problem to solve, students in higher grades are more likely to arrive at different answers than students in lowers grades are.
Higher grades and lower grades students are solving the same basic mathematics
(D) Older students tend to receive higher grades in math than do younger students.
Irrelevant , cannâ€™t say if higher grades are solving complex problems
(E) Universities in this country report a steady increase in the percentage of native firstyear students who qualify to take advanced mathematics courses such as calculus.
Now students are qualifying for advanced mathematics courses â€¦ so the students are aware of complex mathematical skills.

B seems right. Though E is somewhat close.

This CR's wording is too complicated. We need to make many assumptions. If we have to agree with E, then we need to assume that Calculus will have complex math problems and we need analytical tools to solve those complex math problems. How can we assume that?

I assumed this from wordings ...... advanced mathematics courses such as calculus

This is from manhattan's QB.
OA=E

In most weakening and strengthening questions, new and extra information is usually a good sign if you can interpret it right. they are not out of scope.

The correct answer is E. The conclusion of the argument is that "math education in this country does a disservice to our children." Why? Because math teachers emphasize "in higher grades the same narrow, skillsbased approach that students learned in lower grades rather than the analytical tools they will need to solve complex math problems." In order to weaken the conclusion, we need to show that this approach has not had a negative effect on children's math skills. Choice E states that an increasing percentage of native firstyear students qualify to take advanced math courses in college. This would seem to suggest that more children are prepared for advanced math than had previously been the case, thus weakening the conclusion of the argument.

I was confused between B & E for quite some time, but eventually chose the right answer, E. So let me pen down my thoughts on why E. (B) On international tests of math skills, highschool students in this country performed no worse than did their counterparts from countries where problemsolving is emphasized in higher grades.  Even if they did perform on par with foreign students, does that mean we are NOT doing disservice to our students? Of course we are. Because we are focused on improving "our" students.
(E) Universities in this country report a steady increase in the percentage of native firstyear students who qualify to take advanced mathematics courses such as calculus.  If there is an increase in students from high school to universities, and who also qualify to take advanced courses, then it proves that whatever they studied in the last school has definitely helped them make this transition and "qualify" for it.
