We should recognize this as a weakening question: Which one of the following, if true, most seriously weakens the representative’s argument?

Our stimulus is attributed to a Beverage company representative, and he makes a prediction about the effect of a new policy. Thus far, beverage cans have been linked by plastic rings that often harm and suffocate animals when they end up in the environment. All the beverage companies, following the representative’s company’s lead, are going to adopt new plastic rings that disintegrate after three days exposure to sunlight. Sounds like a much better option! The representative concludes with a prediction that once the switchover from the old to the new plastic rings is completed, the threat of suffocation to animals will be eliminated. Our job is to weaken this prediction: we want an answer choice that would reduce the probability that the change, once adopted, will be sufficient to eliminate the threat to animals. On to the answers:

Answer Choice (A) Remember, our representative’s prediction specifies that the elimination will occur once the switchover is complete.

Correct Answer Choice (B) If the original problem is still out there, well then even if it is no longer going to be getting worse a switchover won’t be enough to eliminate the threat of plastic rings to animals.

Answer Choice (C) This doesn’t weaken the prediction at all.

Answer Choice (D) Good for the new rings, but this does nothing to weaken the prediction.

Answer Choice (E) Okay this gives us a reason why the change will harm animals, but remember, we are specifically interested in whether it will eliminate the problem of suffocating.
