P: Complying with the new safety regulations is useless. Even if the new regulations had been in effect before last year’s laboratory fire, they would not have
prevented the fire or the injuries resulting from it because they do not address its underlying causes.
Q: But any regulations that can potentially prevent money from being wasted are useful. If obeyed, the new safety regulations will prevent some accidents,
and whenever there is an accident here at the laboratory, money is wasted even if no one is injured.
Q responds to P’s position by
(A)
extending the basis for assessing the utility of complying with the new regulations - CORRECT. Extending, certainly yes. Even though the word "but" is used Q's response is only adding more color to P's argument.
(B) citing additional evidence that
undermines P’s assessment of the extent to which the new regulations
would have prevented injuries in last year’s laboratory fire - WRONG. Plain wrong and easy to eliminate. red text is certainly not true but blue text text does looks wrong as Q starts his/her argument with "but". However, it may go in either direction thus in blue color.
(C) giving examples to show that the uselessness of
all regulations cannot validly be inferred from the uselessness of
one particular set of regulations - WRONG. Generalises by using the word "all". Though one may get trapped if he/she consider 'regulations = all regulations'.
(D) showing that P’s argument
depends on the false assumption that compliance with any regulations that
would have prevented last year’s fire would be useful - WRONG. Big claim but bigger issue is with prevention of fire which is not what Q says.
(E) pointing out a
crucial distinction, overlooked by P, between
potential benefits and actual benefits - WRONG. There is no distinction neither any benefits discussed.
Usually when two person argument with each other in CR passage, there is a conflict as in one takes one pov and other takes different(mostly opposite). However, this generality should be taken with a pinch of salt. In this passage too Q responds to P's argument by using the word "but" that suggest it might be an opposite view. But it's not as we see in the option choice.
Answer A.
