After a recent lawsuit, Re-Fresh Air Fresheners’ most popular aerosol spray was found to contain dangerous levels of p-dichlorobenzene, a toxic substance which irritates the lungs and mucous membranes and may cause cancer. The company decided to retool its aerosol spray formula and successfully removed all p- dichlorobenzene from its line of household sprays. Re-Fresh Air Fresheners’ aerosol sprays are now less toxic to consumers than ever before.

Which of the following, if true, most weakens the author’s conclusion?

A. The company’s most popular aerosol spray has always contained ammonia, which reacts with chlorinated products to produce deadly chloramine gas.

B. Some people who drink water containing p-dichlorobenzene for many years have become anemic.

C. P-dichlorobenzene has been used widely in Europe for many years as a room deodorizer with no complaints or significant lawsuits.

D. Aerosol propellants still used in some of the retooled formulas may be flammable and may cause nervous system damage if inhaled.

E. Re-Fresh Air Fresheners’ new formula for its most popular aerosol spray now contains trace amounts of petroleum distillates, which are flammable, and may cause fatal pulmonary edema in sensitive individuals.

Why does A not work?

Is it beacuse the ammonia has always been in the formula, thus it has always been toxic?

The conclusion is that the "aerosol sprays are now less toxic to consumers than ever before." but as a result of what?

The premise is that the company removed the "dangerous levels of p-dichlorobenzene, a toxic substance which
irritates the lungs and mucous membranes and may cause cancer."


In answer A, the fact that ammonia has always been in the formula has no bearing on the lower toxicity of the new formula. Its just one chemical in the spray that is toxic. The answer does not strengthen or weaken the conclusion. It merely states a fact about the aerosol spray that was not included in the question stimulus.

Per my Princeton Review guide, the answer to a weaken question will attack an assumption or provide information that makes the conclusion not true.

I guess an assumption in the argument is that when the company retooled the formula they didn't add any new chemicals that would be considered a toxic substance. Answer A does address this assumption or provide any new information as a result of the new formula.

A is a trick which fully destroys the argument. Another trick is D which says that new formula "may be flammable". The E is the best because gives strong relation to new formula which is "flammable"

I don't think that the trick in D is because of "may be flammable". Otherwise, answer E would point to the same flaw. I think that the trick in D lays in the word "Aerosol propellants", which is a generalization. E goes straight to the point of "Re-Fresh Air Fresheners".

Official Explanation

The correct response is (E).
The conclusion relies on the phrase “less toxic” to claim the NEW aerosol sprays and safer than the OLD sprays produced by Re-Fresh. This conclusion will be weakened by any information which proves that the NEW sprays are in fact just as toxic, or more toxic.

The phrase “now contains” in (E) indicated that the harmful petroleum distillates were no present in the old formula, so it’s possible that the new formula is in fact more toxic.

(A) might be tempting, but if both the new and old formulas contain this same ingredient, it does not do enough to prove the new formulas is in fact more toxic, which is a stronger refutation of the conclusion.

Correct E,

A is out of scope because the conclusion says that the "the formula now is less lethal than ever before". So already existing compounds are out of scope.

Only A and E are strong contender.
Can anybody tell me why the answer is E?...In E, the group is narrowed down to only sensitive individuals, where as in A, it is referring to the consumer as a whole, as given in the stimulus..."Re-Fresh Air Fresheners’ aerosol sprays are now less toxic to consumers than ever before."

Thanks in advance...

Ans choice A is chosen the most after correct choice. I would rule out A due to below reason


A. The company’s most popular aerosol spray has always contained ammonia, which reacts with chlorinated products to produce deadly chloramine gas.

Ammonia is present in aerosol, but we need to understand that as per the passage, ammonia by itself is not deadly. It needs to react with chlorinated products. Now we are not sure if the body already has chlorinated products. Hence we cant conclude that present of ammonia is harmful.
