Due to oxidation, the iron components that are utilized in structures formed with reinforced concrete can potentially lose their strength over time, especially in coastal areas with high humidity levels. This phenomenon can be prevented by coating the iron components with a robust secondary substance, such as a polymer with anti-oxidant properties. Therefore, it is certain that buildings constructed in areas with high humidity using reinforced concrete that contains uncoated iron components will suffer structural damage in the form of corrosion due to oxidation.

Which of the following, if true, undermines the author's conclusion?

A) Only when reinforced concrete is mixed disproportionately does it experience a more dramatic chemical reaction, leading to the release of abnormal amounts of heat, and as a consequence, becomes cracked, exposing its inner iron structure to the atmosphere.

B) A range of polymer products with anti-oxidant properties are readily available from suppliers of construction equipment, but are almost always fairly expensive due to the chemical processes and patents required to produce such products commercially.

C) Because of harsher conditions such as above-average moisture levels, strong winds, and higher exposure to sunlight, building materials tend to suffer structural disintegration at much higher rates in coastal areas than in areas that are further inland.

D) Cracking is an inevitable result when concrete is used in large volumes, but if the inner iron components are protected by an epoxy or zinc phosphate layer, and if the cracks are treated early enough, serious weakening of the structure should not not take place.

E) Building projects constructed in coastal areas are usually highly lucrative, and accordingly have higher budgets and the financial potential to invest in superior materials, such as coated iron components for structures built with reinforced concrete.

Though I have a considerable opinion of the question provided by E-Gmat this one is a bit redundant and full of fluff. Gmac says the same things in less than half words.

Back to the question. A clearly wins because it weaks the question at the core

uncoated iron components will suffer structural damage >>>>>>>>>>

Only when reinforced concrete is mixed disproportionately does it experience a more dramatic chemical reaction



The other options are all out of scope

Not a 600 level question

hope this helps.

This is NOT an e-GMAT question.

I agree with carcass though. The question is horribly worded.

GMAT does not create sentences in CR that it considers wrong in SC.

(Due to oxidation, the iron components that are utilized in structures formed with reinforced concrete...)

Even though this question is wordy, it should still be practiced because current trend in GMAT is questions with long stimulus.

Due to oxidation, the iron components that are utilized in structures formed with reinforced concrete can potentially lose their strength over time, especially in coastal areas with high humidity levels. This phenomenon can be prevented by coating the iron components with a robust secondary substance, such as a polymer with anti-oxidant properties. Therefore, it is certain that buildings constructed in areas with high humidity using reinforced concrete that contains uncoated iron components will suffer structural damage in the form of corrosion due to oxidation.

Which of the following, if true, undermines the author's conclusion? <- Weakening Question

A) Only when reinforced concrete is mixed disproportionately does it experience a more dramatic chemical reaction, leading to the release of abnormal amounts of heat, and as a consequence, becomes cracked, exposing its inner iron structure to the atmosphere. <- This option Introduces a lot of new info but also weakens the conclusion. In doubt, keep it as contender.

B) A range of polymer products with anti-oxidant properties are readily available from suppliers of construction equipment, but are almost always fairly expensive due to the chemical processes and patents required to produce such products commercially. <- Out of Scope.

C) Because of harsher conditions such as above-average moisture levels, strong winds, and higher exposure to sunlight, building materials tend to suffer structural disintegration at much higher rates in coastal areas than in areas that are further inland. <- Talking about structural disintegration but does not affect the conclusion of argument.

D) Cracking is an inevitable result when concrete is used in large volumes, but if the inner iron components are protected by an epoxy or zinc phosphate layer, and if the cracks are treated early enough, serious weakening of the structure should not not take place. <- Strengthening

E) Building projects constructed in coastal areas are usually highly lucrative, and accordingly have higher budgets and the financial potential to invest in superior materials, such as coated iron components for structures built with reinforced concrete.[/quote] <- Out of Scope.

Should be A.
A says that exposure of iron occurs only when products are mixed disproportionately.. So it weakens the conclusion that structural damage is CERTAIN.

Therefore, it is certain that buildings constructed in areas with high humidity using reinforced concrete that contains uncoated iron components will suffer structural damage in the form of corrosion due to oxidation.

Which of the following, if true, undermines the author's conclusion?

A) Only when reinforced concrete is mixed disproportionately does it experience a more dramatic chemical reaction, leading to the release of abnormal amounts of heat, and as a consequence, becomes cracked, exposing its inner iron structure to the atmosphere. -Correct. The passage assumes that the concrete WILL get cracks. What if it never cracks?

B) A range of polymer products with anti-oxidant properties are readily available from suppliers of construction equipment, but are almost always fairly expensive due to the chemical processes and patents required to produce such products commercially. -This is just a statement, unrelated to the argument

C) Because of harsher conditions such as above-average moisture levels, strong winds, and higher exposure to sunlight, building materials tend to suffer structural disintegration at much higher rates in coastal areas than in areas that are further inland. -This strengthens the argument

D) Cracking is an inevitable result when concrete is used in large volumes, but if the inner iron components are protected by an epoxy or zinc phosphate layer, and if the cracks are treated early enough, serious weakening of the structure should not not take place. -This is a strengthener.

E) Building projects constructed in coastal areas are usually highly lucrative, and accordingly have higher budgets and the financial potential to invest in superior materials, such as coated iron components for structures built with reinforced concrete. -The argument is talking about iron NOT coated with any material
