Until now only injectable vaccines against influenza have been available. They have been primarily used by older adults who are at risk for complications from influenza. A new vaccine administered in a nasal spray form has proven effective in preventing influenza in children. Since children are significantly more likely than adults to contract and spread influenza, making the new vaccine widely available for children will greatly reduce the spread of influenza across the population.
Which of the following, if true, most strengthens the argument?
A. If a person receives both the nasal spray and the injectable vaccine, they do not interfere with each other.
B. The new vaccine uses the same mechanism to ward off influenza as injectable vaccines do.
C. Government subsidies have kept the injectable vaccines affordable for adults.
D. Of the older adults who contract influenza, relatively few contract it from children with influenza.
E. Many parents would be more inclined to have their children vaccinated against influenza if it did not involve an injection.

OA:D

I am not able to figure out the correct option. Every option just looks so blur. RON please explain the approach you would take to reach the answer and also explain your views and reasoning for each option.

thanx..!!

something is wrong here. choice (d), which works against the argument, is definitely not the correct answer to this problem.

1) is this problem from the GMAT PREP SOFTWARE? it doesn't seem to be from that software, according to a quick google search.
if it is indeed a gmat prep question, please post a screenshot (either here or with a link to postimage.org) as proof.

2) if the problem is not from the gmat prep software, then please (a) check that it is not from a banned source, and, if it's not, (b) post a new thread in the general verbal folder. if you do so, be sure to check your source again; perhaps you are looking at a different version of another problem.

OA is (D)

The questions are different in the image and in the first post.

The OA to the first post is 'E' and OA to the question in the image is 'D' and both the questions and the sentences in the separate posts are miles apart !

Yeah, we’re just going to ignore this one until we have more information..

Why D is wrong in initial problem.
D. Of the older adults who contract influenza, relatively few contract it from children with influenza.

Is it because vaccine is already available for adult or just because few adult get infected from children?

I convinced that E is strengthener.

Thanks for the screenshots. Hopefully people will see now where the confusion came from. And since the screenshots confirm that E is the answer for this problem, i assume that clears up any question about why D seemed so wrong..
