help resolve a CR question
The owners of an bicycle manufacturing company, unhappy that 20% of their new "Street Fleet" bicycles came back for repair within 6 months of purchase, recalled every "SF" bicycle and altered them to make them less susceptible to ordinary wear and tear. They improved the construction by swiching to an equally lighweight but sturdier metal, and by increasing the number of spokes supporting the rim. The company renamed the new bikes "Rough Rider", and in 6 months sold roughly the same number of these as the original "SF". Despite the improvements, 50% of the "RR" came back for repairs within 6 months of purchase.
Which one of the following, if true, most helps to explain the unexpected results noted in the passage?
A, The higher costs of the new manufacturing process have forced the owners to close one of their two service centers.
B, The company's new promotional literature on the "RR" now appeals to customers more apt to ride the bikes on unusually rough terrain.
C. The company has broadened its warranty on the "RR" so that it now covers parts as well as labor.
D. The aerodynamic design, initially suspected to cause the "SF" to veer slighly leftward at top speeds, was not corrected in the "RR".
E. The bikes still use a braking system that puts an unusually large amount of pressure on both front and back rims.
