Increased use of autonomous delivery drones is sometimes advocated as a safe way to transport packages in crowded urban areas. But opponents of drone delivery point to the 60 incidents involving unexpected loss of control that were reported just last year at two existing drone-delivery companies operating in major cities. Since designs for proposed new drone fleets include no additional safeguards to prevent such losses of control, accidents will only become more prevalent if use of drone delivery increases.
Delivery drone is advocated safe in urban areas, but recent 60 incidents in last 2 years in major cities has raised questions...
loss of control as no additional safeguards present , accidents occuring can become common..
need to weaken the conclusion
Which of the following, if true, most seriously weakens the argument?
(A) In only a small fraction of the reported incidents did a drone’s loss of control result in property damage or injury. this does not weaken the conclusion as given reasoning is not aligned to argument
(B) Other methods of package delivery, such as bicycle couriers, have not been proven less accident-prone than drone delivery.
not relevant to argument to make it weaken
(C) The current fleets at existing drone-delivery companies are large enough to handle increased delivery volume without any need for new drones. could be valid but does not address the main theme of arguement i.e. accidents prevention..
(D) The frequency of unexpected loss-of-control reports in newly launched drone fleets is about the same as the frequency in older fleets.
irrelevant to argument
(E) At the two companies where losses of control were reported, many drone operators had received only minimal training on how to intervene when automated systems malfunctioned.
provides alternate reasoning for loss of control and issues... if addressed properly accidents of drone can be prevented..
OPTION E is correct
