Reading skills among high school students in Gotham have been steadily declining, which can only be the result of overcrowding in the schools


Which of the following, if true, most seriously weakens the argument expressed above?
(A) The high school system in Gotham succeeds in giving students a good education at considerably less cost than do most systems.
(B) Several cities have found that overcrowding in the schools is not always associated with lower reading scores.
(C) Gotham schools have a greater teacher-to-student ratio than most other school systems.
(D) Students' reading skills have not declined in other cities where the high schools are just as crowded as those of Gotham.
(E) Schools are not overcrowded in many cities where high school reading scores have declined more than they have in Gotham.

Pls help why option B is incorrect?

Please provide your reasoning while marking B as the answer. Based on that only, we can find out where you were missing.

Here, The cause is overcrowding which has resulted into declining reading skills.

Hence, if we can identify that some other cause has given resulted in declining reading skills, we can weaken the argument.
Option B says that overcrowding is not associated with lower reading scores. Hence, something else is associated with it .

Please advise, what flaw is there in this reasoning.

e) Schools are not overcrowded in many cities where high school reading scores have declined more than they have in Gotham.

Please justify your options. I feel two options (d & e) are correct. Stimulus suggests that overcrowding in the schools (cause) leads to decline in reading skills among high school students in Gotham (Effect).
Option d states effect does not occur even when the cause occurs.
Option e states effect occurs even when cause has not occurred.
How do you justify one option over the other as both seem to weaken the argument.


clearly, all but D and E can easily be eliminated.
I chose E.
no cause -> effect still is present. thus, cause does not lead to effect.

Please clear my doubt

E says many cities but not all other cities, leaving a scope for some other cities similar to Gotham?

D says about all other schools that are just as crowded as Gotham, so narrowed down to the required comparison?

B says not always, meaning sometimes may be possible, same like E says ?

C is saying a different reason but that reason was not properly associated with the decline or incline in the scores, so can be skipped

A This adds no value
