+1, also isn't our reasoning flawed if we use past to justify/predict future trends ?

Bunuel
Research in the nation of Veloria shows that only 18% of Velorians under 30 volunteer their time, while over 65% of Velorians over 30 participate in volunteer activities regularly. Despite the younger population forming a significant segment of society, nonprofit organizations predict that in ten years, the percentage of Velorians who engage in volunteer activities will likely remain stable or even increase.

Which of the following, if true, provides the strongest grounds for the nonprofits' prediction?


A. The number of Velorians under 30 is less than the number of Velorians over 30.
B. The number of nonprofit organizations in Veloria has increased significantly in the past decade.
C. The research defined a regular volunteer as someone who volunteers at least once a month.
D. The percentage of Velorians who engaged in volunteer work was higher 25 years ago than it is today.
E. The rate of volunteer participation among Velorians under 30 has traditionally been low.
Hi Bunuel,

Research in the nation of Veloria shows that only 18% of Velorians under 30 volunteer their time, while over 65% of Velorians over 30 participate in volunteer activities regularly. Despite the younger population forming a significant segment of society, nonprofit organizations predict that in ten years, the percentage of Velorians who engage in volunteer activities will likely remain stable or even increase.

Which of the following, if true, provides the strongest grounds for the nonprofits' prediction?


A. The number of Velorians under 30 is less than the number of Velorians over 30.


If we assume The number of Velorians under 30 (say 1lakh) is greater than the number of Velorians over 30(say 1000)
then according to premise 18%(1lakh) > 65%(1000) so in coming years more number of people would volunteer their vote as the majority is now under 30 --> so it will support the claim that it volunteer activity would increase.
On the other hand say in ten years most of them croosed 30 who are currently below 30 and more number of people comes in the category of below 30 --> then the eprcentage can remain stable

we can also think as:= overall participation rate to stay stable or increase, either:

Older adults (30+)—who volunteer at a high rate—must make up a large portion of the population, or Younger people must start volunteering more If there are fewer young people, then their low volunteering rate has less impact on the overall rate. And since 65% of older people volunteer regularly, their greater numbers can offset the low participation of the youth. Hence, the overall volunteer rate can remain stable or increase.


whats wrong with this thinking ? please help

HiBunuel this question came in one of the sectional mocks. The reasoning for the solution is not convincible. Can you help with the source and OA, if any.

Bunuel Nevermind, through another question link I got the knowledge of it being an in house question, since in house questions are considered in the sectional mocks. I just found 'E' not too rewarding in the sense of how it is presented and its meaning, since I was trying to understand how 'E' would allow the percentage of Velorians engaging in volunteering activities increase.

Thank you for the comment. I very much understand your point about the "rewarding" answer and it does feel pretty unsatisfactory when the answer is lukewarm but all are present on the GMAT, so getting used to these helps getting over that uneasy feeling of "did I really answer the question; is this really the best one". The answer was purposefully unsatisfactory. I am sorry for that :angel:
