A proposal for a new building fire safety code requires that fireretardant insulation no longer be sprayed on steel girders in the factory, but be sprayed on once the girders have arrived at the building site. This will eliminate the dislodging of the insulation in transit and reduce fatalities in catastrophic fires by an estimated 20%.
Which of the following, if true, represents the strongest challenge to the new proposal?
(A) The fire-retardant insulation will also be required to be one inch thicker than in the past.
(B) Studies have shown that most dislodgement of insulation occurs after the girders arrive on site.
(C) Catastrophic fires represent only 4% of the fires reported nationally.
(D) The proposed safety code will add considerably to the cost of new construction.
(E) In most of Europe, spraying fire-retardant insulation onto steel girders at the building site has been required for the past ten years.

Proposal - A proposal for a new building fire safety code requires that fireretardant insulation no longer be sprayed on steel girders in the factory, but be sprayed on once the girders have arrived at the building site.
Premise - This will eliminate the dislodging of the insulation in transit and reduce fatalities in catastrophic fires by an estimated 20%.
Which of the following, if true, represents the strongest challenge to the new proposal?
So, we are required to find an answer choice that opposes the proposal.
(A) The fire-retardant insulation will also be required to be one inch thicker than in the past.
Incorrect. The thickness of the insulation has not been mentioned in the argument. Moreover, the thickness of the insulation does not opposes the proposal.
(B) Studies have shown that most dislodgement of insulation occurs after the girders arrive on site.
Correct. If this is true, then the proposal of spraying fire-retardant insulation at the building site will not achieve the desired result of eliminating the dislodging of the insulation in transit and reduce fatalities in catastrophic fires.
(C) Catastrophic fires represent only 4% of the fires reported nationally.
Incorrect. Out of scope answer choice.
(D) The proposed safety code will add considerably to the cost of new construction.
Incorrect. Out of scope answer choice.
(E) In most of Europe, spraying fire-retardant insulation onto steel girders at the building site has been required for the past ten years.
Incorrect. If this was required in the past then the proposal is strengthened and not opposed.

B
The words strongest challenge in the question mean that you are trying to weaken the argument. Choice A, if anything, appears to support the argument rather than weaken it, so you can eliminate it. Choices C and D do seem negative toward the argument, but both are outside the scope, as is choice E. Choice B is best because if the insulation comes loose after the girders arrive on site, then making an effort to prevent its dislodgement in transit to the building site will not have any effect and will not necessarily reduce fatalities.
