Official Solution:
Which of the following most logically completes the passage?
Because of the increasing number of injuries caused to children who start learning bicycles and in the process frequently fall down, bicycle manufacturers will soon be required to provide children’s bicycles with an additional fall-proof mechanism that can be engaged or disengaged as per the wish of the rider. However this regulation would most probably not retard the rise of the number of injuries from falling from a bicycle because the fall-proof mechanism slows down the learning process by providing extra stability that is not experienced while riding a standard bicycle without such a mechanism and ___________
A. parents cautiously engage the safety mechanism before the children go out riding bicycles.
B. bicycles with the additional safety mechanism would be expensive and hence there will be a drop in the sales of childrens’ bicycles.
C. as many as 80% of the new learners have been reportedly injured at least once by falling from a bicycle.
D. the injuries resulting from falling from bicycles are in most cases not serious.
E. children wish to learn to ride bicycles unaided by any additional safety mechanism as fast as they can.
The structure of the argument in the passage is as follows:
Conclusion: The rise in the number of injuries will not be retarded.
Premise 1: The mechanism slows down the learning process
Premise 2: ….. (to be selected from the list A to E)
Apparently premise 1 by itself does not have direct bearing on the conclusion, unless we introduce premise 2 that complements premise 1 in such a way that premise 1 and premise 2 collectively lead to the conclusion.
A. This option gives a reason that the rise in the number of injuries would be retarded. If the parents engage the safety mechanism, it is more likely that there would be fewer cases of injuries from falling down from the bicycle.
B. This option also gives a reason that the rise in the number of injuries would be retarded. If there are fewer bicycles sold, it is likely that fewer children would ride bicycles and hence there would be fewer injuries.
C. This option is irrelevant. What proportion of the children are injured has no bearing on determining whether the new regulation would have an effect on retarding the rise in the number of injuries.
D. This option is irrelevant. Whether the injuries are serious has no bearing on determining whether the new regulation would have an effect on retarding the rise in the number of injuries.
E. CORRECT. This option in conjunction with premise 1 gives a reason that the rise in the number of injuries would not be retarded. If the children want to learn to ride a bicycle unaided by a fall-proof mechanism
as fast as they can and the fall-proof mechanism
slows down the learning process, it is likely that the children would disengage the mechanism while riding; therefore introducing the mechanism would not have an effect on the rise in the number of injuries because the mechanism would not be used whatsoever. Here it is to be noted that the regulation requires the manufacturers to provide a fall-proof mechanism on children’s bicycles but does not require the children to engage such a mechanism while riding.
