Critical Reasoning

Height requirements on roller coasters can help riders avoid injuries . The steeper the roller coaster the more likely an injury will occur , so the restrictions are more important on these rides . Consequently the only roller coaster rides that have height requirements are those with inclines of more than 35 degrees.
which of the following conclusions could be most properly drawn from the information given above ?
A)On some roller coaster rides people taller than the height requirement are as likely to be injured as people shorter than the height requirement .
B)On roller coaster rides with inclines greater than 35 degrees , steepness is the primary factor in the severity of injuries
C)The number of injuries on roller coaster rides with inclines less than 35 degrees is greater than that on rides with height requirements
D)It is likely that fewer injuries occur on rides with very steep inclines than on those with inclines less than 35 degrees
E)Height requirements will likely prevent more injuries on rides with inclines greater than 35 degrees than on those with inclines less than 35 degrees

OA E
In E even if height requirements were able to prevent 5 injuries on inclines greater than 35 degrees and only 2 injuries on inclines than 35 degrees , it would be still worth imposing height requirements on inclines less than 35 degrees.
I dont agree with OA . At the same time i am hungry for an explanation .
