Hi Adit_ Let me try to help

Increased use of autonomous delivery drones is sometimes advocated as a safe way to transport packages in crowded urban areas.- Authors presents info about autonomous deliver drones and it has been advocated as a safe to deliver in some cases
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.- Now author presents a contradiction by stating the view point of opponents of drone delivery, opponents cites a case of incidents at two DD companies
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.- Author presents his final view that proposed new drone fleets will still lead to incidents because these proposed ones doesn't have additional safeguards.

So what author is assuming that, absence of additional safeguards will lead to increased cases of incidents, He is not considering other scenarios might caused the incident.

Since you have query in Option B and E lets loot at them

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.- We already know incidents so not helping
B. Other methods of package delivery, such as bicycle couriers, have not been proven less accident-prone than drone delivery.- it compares other option available for delivery, but the argument is not concerned about other options, we need to weaken the conclusion related to drone delivery. even if other options are on similar level of incidents, how does it weaken, it might even strengthen that incidents will happen. so out
C. The current fleets at existing drone-delivery companies are large enough to handle increased delivery volume without any need for new drones.- again not bothered about current ones are enough or not, not helping
D. The frequency of unexpected loss-of-control reports in newly launched drone fleets is about the same as the frequency in older fleets.- It says frequency of incidents is same in both type of fleets, so again somewhat strengthening
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.- It presents the other cause of incident, and thats what most seriously weaken the conclusion that incidents can be controlled

Hope this helps

Option E I felt was irrelevant though. The fact of operators having minimal training need not be correlated to how dangerous a drone is at all. IMO it makes a serious assumption here, I can see how it weakens if looked through a very particular, narrow lens. I can also make similar assumption for option B similarly tbh. Kindly help me out.

Conclusion: 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

This is a clear case of cause-effect CR problem, one of the ways to effectively weaken it is by finding the potential alternative cause, operator's incompetency is an alternate cause. E states exactly that.
We are not assuming anything here, rather we are attacking the assumption in the question by creating a reasonable doubt on the argument that design flaw is causing the accidents.
Therefore E is correct.

B just says that bicycle courier is prone to more accidents, does that affect the argument of "design flaw in drone causing the accidents" ? No they are clearly unrelated, what so ever.

Hope it helps!!

Just a small doubt.

Here does more prevalent indicate higher frequency? if it does then it that case would D be plausible?

Hi adconsectetur yes more prevalent is indicating frequence will be high. And D is basically strengthing making us believe that there is no change in new and old fleet.
