Here is my reasoning
Cause - design doesn’t include additional safeguard to prevent loss of control
Effect - 60 drones losses control

Assumption - designs are the reason for loss of control

E tells us that no design is not the reason, real reason is the operator lack of training.

Answer = B

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.
Argument = bold italics

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.
Unrelated to argument, doesn't matter if property damage or injury

(B) Other methods of package delivery, such as bicycle couriers, have not been proven less accident-prone than drone delivery.
If other methods have same or more proneness to accident, then drone delivery might not be the reason for increase in accidents, hence weakens the argument.

(C) The current fleets at existing drone-delivery companies are large enough to handle increased delivery volume without any need for new drones.
Irrelevant to argument, capability of existing drones is not relevant

(D) The frequency of unexpected loss-of-control reports in newly launched drone fleets is about the same as the frequency in older fleets.
Neither strengthens nor weakens

(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.
No mention that trainings would be increased, hence doesn't weaken the argument

conclusion= accidents will be more common if use of drone delivery increases.
reason= new design doesnt have additional safeguards to prevent loss of control
60 incidents in 2 major companies.

A,B,C are irrelevant / out of scope
D strengthen it rather
E clearly weaknes it. it was operators mistake and not design problem

Answer choice: (E)

Conclusion: The argument concludes that accidents involving unexpected loss of control will become more prevalent as drone delivery increases.

Key assumption: Reported incidents must be caused by something inherent to the drones themselves, such as their design and therefore would scale as drone usage increases.

Weaken strategy: Identify an alternative explanation for the incidents that is not inherent to the drones and therefore would not necessarily carry forward as drone delivery expands.

Why (E): It introduces lack of training as an alternative explanation for the reported incidents. Since inadequate operator training is not inherent to the drones themselves, improving training could reduce such incidents. Therefore, increased drone use would not necessarily lead to more accidents, which weakens the argument.

Why not the others:
(A) Focuses on the severity of incidents rather than their prevalence.
(B) Introduces a comparison with other delivery methods, which is not relevant to the argument.
(C) Suggests few drones may be needed, but does not address the cause of the incidents.
(D) Suggests no increase in frequency but still does not explain why the original incidents occurred.

Premises:
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,

Conclusion:
accidents will only become more prevalent if use of drone delivery increases.

This is a weakening question, and here the passage assumes the loss of control in autonomous drones is because of machine design not having any safeguards, if we could weaken this claim, we can easily solve this question.

(A) In only a small fraction of the reported incidents did a drone’s loss of control result in property damage or injury.
We are not bothered with consequences of the incidents, this is clearly not a weakener. Eliminate.

(B) Other methods of package delivery, such as bicycle couriers, have not been proven less accident-prone than drone delivery.
Doesn't matter even if the other courier were better, the argument is about absence of safeguards in drone design causing incidents. Eliminate.

(C) The current fleets at existing drone-delivery companies are large enough to handle increased delivery volume without any need for new drones.
We are not bothered about handling about drones, conclusion is about safeguards in drone design responsible for incidents. Eliminate.

(D) The frequency of unexpected loss-of-control reports in newly launched drone fleets is about the same as the frequency in older fleets.
Even if it's same as old feet the incidents still happen and we still might need safeguards. Eliminate.

(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.

This gives us an alternate reason for malfunctioning, drone operators having minimal training on how to intervene during a malfunction, so it may not be a design flaw. Keep.

Correct Answer: E

Question says:
Auto Drone delivery System(ADDS) is safe, otpponests of drone delivery say no , stating that last year there were 60 incident involving ADDS in two company in major state,
They conclude they as new design dont prevent them it is not safe them to use ADDS in large scale and numbers will incraese in large scale
We need to say no despite n change it design the number will not increase and ADDS is safe
A)strengthen(out)
B)others vs ADDS don't care(Out of scope)
C)can meet the goal, (out of Scope)
D)old vs new (have to take new assumption to make it true so out)
E) E says its not that the design was bad but there were not trained so nothing to do with design.Therefore E is the weakener.

In order to weaken the argument.
Let us the argument is if don't delivery increases, it is said that accidents will also be more because of the incidents that's occurred for the current rate of drone deliveries happening

The counter should be to prove other methods aren't any sophisticated or less accident rate than drone which is mentioned by option b that bicycle or other modes of delivery aren't any safe than drone deliveries

Therefore option b is the answer

Premise:
Some issues occurred with previous drones. No new changes are made to the drone.

Conclusion:
Drone accidents will only increase

Gap:
What if something else changed?
- like the weather is now more conducive
- or the pilots got better training
- The mapping system has gotten better
- now better signaling system is present


A. no impact. How bad is the damage is not the point of argument.
B. no impact. Comparing other methods of delivery to measure how safe drone delivery is is useless for the argument
C. no impact. But no additional measures were taken to guard against the issues.
D. Strengthener. If the frequency is same, then the author's point the it will only increase is a bit amplified.
E. Correct. If it is due to pilots not getting proper training, then even without any changes to the drones, we can expect a decline in accidents.

It could be derieved from argument that, there are shortcoming in the build of drones that has caused the delay. Cause the argument says that since there are no additional safeguard added in new drone design, accidents will rise. Meaning if safeguards would have been added, then accidents might not have added.
There is a clear relation between build of drone and accidents.
So any option that tells that accidents were not because of build but for some other reason will be the answer.
Option E -> it says it was minimal training that could have caused the accident, not the build of drone. It weakens reasoning given in argument.

Conclusion - Accidents will only become more prevalent if use of drone delivery increases
Line of reasoning - the 60 incidents involving unexpected loss of control that were reported last year

We have to weaken the conclusion; we can say the accident is not because of the drone fault but because of something else
Option A - talks about only small fraction of incidents result in damage - damage is still damage, eliminate it
Option B - comparing bicycle to drones is out of the scope - eliminate it
Option C - doesn't talk about damage - eliminate
Option D - frequency of loss is same as the older fleets, okay? how does it help us? - eliminate it
Option E - gotcha! clearly says the fault is of drone operators as they had only minimal training

Our answer is Option E

A: Even if it was a small fraction, if the drone delivery increases, the NUMBER of mishaps increase. NOt the asnwer
B: OOS
C: Similar to A. Even if I am using the same drone, if the number of deliveries go up, the fraction remains same and the number of accidents that are drone prone go up.
D: Again from the same family as A and C.
E: This tells that it was not the drone but the untrained users that led to accidents. This will lead to number go down if they are trained. Weakens. Answer.

I believe E is the best answer.

The claim of the argument is that if drone deliveries increase, loss of control incidents will also increase. We need something that breaks this direct relationship.

A - Does not address the nature of the direct relationship, merely tries to mitigate the magnitude of the damage of the incidents, irrelevant
B - We are only concerned with whether drone deliveries will continue to cause these accidents, not about other methods of delivery
C - The argument is not saying that an increase in the number of drones used will cause more accidents, its simply saying that increased deliveries made will cause more accidents, so the fact that existing drone infrastructure can handle expected demand is not relevant
D - This says that the frequency / likelihood of accidents is neither improving nor getting worse based on new drone technology. It does not opine on whether accidents will become more prevalent.
E - If the two companies' drone operators had minimal training, this paints the picture that the incidents might not be indicative of a larger pattern and the initially identified direct relationship might not hold if proper training were to be implemented. Correct.

I will go for E.

Let's look at the line of reasoning by the author.

Evidence- loss of control incidents reported at two companies, and the new proposed drones did not have any safeguards to prevent such incidents

Conclusion- If the delivery from drones increases, there will be an increase in incidents.

The question asks to weaken the argument.

Prethinking: The author thinks that the incidents happened because the existing safeguards were not sufficient, or there were no safeguards in the drones. He assumes that only adding the safeguards will prevent the incidents from increasing.

So if we prove that the author's thinking is wrong with some other reasons, then that will be our weakner.

Option E gives us the reason that the incidents happened because the operators were not trained enough.

Now, why are other options incorrect:

A. This gives extra info about the incidents that happened, but it didn't provide us with any reason to doubt the conclusion. Not relevant
B. Unnecessary comparison between entities.
C. This states that drones are not needed, which means the old drones will transport the package. So, what we still cannot question the conclusion
D. New vs Old fleet of drones and frequency of both fleets are the same, and if the number of drones increases, the incidents increase. Hence, it strengthens rather than weakens.

Solution:

1. It only talks about the a small fraction of the reported incidents due to loss of control whereas the passage states about increase in accidents due to use of drone diivery. So, Incorrect.

2. This choice only comparison between incidents reported such as the couriers delivered by bicycle and drone delivery. So, Incorrect.

3. It talks about the existing drone delivery companies are good enough to handle increased delivery volume then new drone company. So, Incorrect.

4. This choice only discusses about the loss by the newly as well as the older fleets. So, Incorrect.

5. This choice weakens the conclusion as it states that the drone accidents occured due to minimal training provided to the drone operators on how to handle when automated systems malfunctioned. So, this the correct one.

The main conclusion of the argument is "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". From here we are getting one key assumption : argument is pointing towards design mis handling failure as cause towards these accidents. We need to weaken the argument. If we look at option E carefully it points towards human mishandling since it says that operators didn't get enough training to operate the drones. This create a sense of doubt in the boardroom for this possibility. Other options are not attacking the assumption. So clearly E is the answer.

The answer is E. What is true for the two existing drone companies might not necessarily be true for all. A, B, C is irrelevant, even if a small fraction of damage is reported on property damage, there is still damage and it doesn't help weaken the claim that accidents will become more prevalent with the increased use of drones, similarly comparing drones to bicyles doesn't help weaken the claim. We are not concerned with increased delivery volume hence C is out. D just strengthens the claim that more accidents can occur with the same design due t the matched frequencies. E bring isn another factor showing that it is not necessarily the design but faulty training of operators causing the accident, hence E is correct.
