Critical Reasoning (CR) | In Wareland last year, 16 percent of licensed drivers under 21 and 11

­If we negate the option E from the questiongiven.
(E) There is no an age bracket for which the accident rate is lower than it is for licensed drivers 65 andolder.

This negated assumption implies that there will be an age group, for example 40-45 has less serious accident rates then 65 and older. And the above implication will put the conclusion at risk which states that "the greater experience possessed by drivers in the 65-and-older group make them far safer behind the wheel than the younger drivers".

One can arguethat  The conclusion is comparing drivers 65 and older to younger drivers, specifically those under24 . But no where, in the conlclusion I can see explicit mention of it and even conclusion called out that "65-and-older group make them far safer behind the wheel than the youngerdrivers ". So, does 25-64 are not considered younger than65?
