Studies have demonstrated that many immigrants to the United States receive excellent scores on the mathematics portion of standardized college entrance examinations. The high-quality mathematics education these people received in this country during their formative years is primarily responsible for this phenomenon.

Which of the following, if true, most seriously weakens the explanation above?

A. Immigrants who take standardized college entrance exams are not representative of the general population of immigrants, since only a small percentage of these people are college-bound.
B. Some educational experts are highly critical of the notion that standardized test scores can accurately indicate a student's level of college preparedness.
C. Average scores on standardized college entrance examinations have declined every year for the past two decades.
D. Because most immigrants are not native English speakers, their performance on the verbal portion of standardized college entrance exams is weak compared to that on the mathematics portion.
E. Immigrants who arrived in the United States after the age of 18 score just as high on the mathematical portion of standardized tests as those arriving at a very young age.

+1 D (I am not too happy, but this is the best I got)

Premise - Studies have demonstrated that many immigrants to the United States receive excellent scores on the mathematics portion of standardized college entrance examinations.

Conclusion - The high-quality mathematics education these people received in this country during their formative years is primarily responsible for this phenomenon.

Any options which weakens the conclusion is our answer

A. Immigrants who take standardized college entrance exams are not representative of the general population of immigrants, since only a small percentage of these people are college-bound. (We are not talking about the whole population but those who take the examinations, it will make a good answer in case of an absence of any other better answer)
B. Some educational experts are highly critical of the notion that standardized test scores can accurately indicate a student's level of college preparedness. (Irrelevant)
C. Average scores on standardized college entrance examinations have declined every year for the past two decades. (Irrelevant)
D. Because most immigrants are not native English speakers, their performance on the verbal portion of standardized college entrance exams is weak compared to that on the mathematics portion. (This is our answer, the non-natives have a weak english and therefore they study maths more to get a competitive score, thus weakening the conclusion that the high-quality mathematics education these people received in this country during their formative years is primarily responsible for this phenomenon)
E. Immigrants who arrived in the United States after the age of 18 score just as high on the mathematical portion of standardized tests as those arriving at a very young age. (Irrelevant)

IMO A...
the question stem states that the immigrants get high math scores because of the education in their country. And A counters exactly that. The people who get the high scores do not represent the entire population hence do not reflect on the education system.

E. Immigrants who arrived in the United States after the age of 18 score just as high on the mathematical portion of standardized tests as those arriving at a very young age.

I'm having some difficulty understanding the wording of the stem. Is the part I've highlighted in red intended to read "in their country"? As the question is written now, the argument makes no sense, since it is not at all clear what country "this country" refers to. Perhaps they mean "in the US", but then we need to assume the author of the passage is writing from the perspective of an American. The argument hinges on this point so the stem shouldn't be ambiguous about it.

If I assume the question ought to read how I've suggested, then the answer should be E. The question stem says that many immigrants to the USA receive high scores on tests, and explains that it is the education "these people received" in their own countries which is responsible. Since the argument is only about the education that the *test-takers* alone received, we don't particularly care about immigrants who are not test-takers. So while A looks like a good answer, it is not correct. What we do care about is comparing test-taking immigrants who were educated in their own countries with test-taking immigrants who were educated in the USA. Then we will have some basis for comparing US education with other countries' education, which is what the argument is all about. That's what makes E the best answer; E suggests that it makes no difference to test scores whether immigrants were educated in the USA or elsewhere.

Studies have demonstrated that many immigrants to the United States receive excellent scores on the mathematics portion of standardized college entrance examinations. The high-quality mathematics education these people received in this country during their formative years is primarily responsible for this phenomenon.

The argument states that the immigrants to the United States receive excellent scores on their mathematics portion of standardized college entrance examinations and this result is due the to high-quality mathematics education these people received in this country during their formative years.

A. Immigrants who take standardized college entrance exams are not representative of the general population of immigrants, since only a small percentage of these people are college-bound. - we are talking about immigrants who take tests and score more and not about immigrants as a whole. So it doesnt weaken.
B. Some educational experts are highly critical of the notion that standardized test scores can accurately indicate a student's level of college preparedness.-doesnt seem to weaken
C. Average scores on standardized college entrance examinations have declined every year for the past two decades.- Average scores declined.doesnt matter as we're bothered about immigrants who take tests scoring more.
D. Because most immigrants are not native English speakers, their performance on the verbal portion of standardized college entrance exams is weak compared to that on the mathematics portion.- saying that they're weak in verbal doesnt seem to weaken that they score more in mathematics. the question stem is "The high-quality mathematics education these people received in this country during their formative years is primarily responsible for this phenomenon" anything about verbal is irrelavant.
E. Immigrants who arrived in the United States after the age of 18 score just as high on the mathematical portion of standardized tests as those arriving at a very young age.-weakens by saying that the formative education they receive in that particular country is not the reason because even immigrants who arrived after the age of 18 score as high as the other immigrants on the mathematical portion.

Although we both are wrong

E is the answer.

Someone explain these question.
A or E

I am still not satisfied with correct answer as E

In E

Immigrants who arrived in the United States after the age of 18 score just as high on the mathematical portion of standardized tests as those arriving at a very young age.

IMO these statement implies immigrants after the age of 18 or young have strong mathematic portion of standardized tests.
So how E is right?

In A
It talks about whole immigrants population which is stated in premise.

"Studies have demonstrated that many immigrants to the United States..."

clear the ambiguity....guys

I would go for E.

E weakens the argument by stating that even students who came to america at the age of 18 and not during the formative years have scored the same high score.This weakens the argument which says that the strong primary education which the students have undergone in america is responsible for the high score.

Hi Aristocrat

Look at the conclusion carefully

“The high-quality mathematics education these people received in this country during their FORMATIVE years is primarily responsible for this phenomenon”

Option E states that THOSE immigrants who had their formative years of STUDY IN US also have equivalent mathematics knowledge than those who came after 18.

This implies that the formative years of study is not responsible because if it would have been then those who came after 18 should have scored more in mathematics than those who were raised and taught in US.

Hope this helps!
