Zorluk: KolayStrengthening Arguments

A logistics company recently replaced its human-driven delivery fleet with autonomous electric vans in City Y. Over the subsequent six months, management noted a sharp decrease in parcel delivery delays across the city. Management concluded that switching to autonomous electric vans was directly responsible for the improved delivery timeliness. Which of the following, if true, most strongly supports management's conclusion?

  1. During the six-month period, City Y experienced no major changes in traffic congestion, road construction, or total parcel volume.Cevap
  2. B
    Human-driven delivery fleets operating in neighboring cities also experienced a similar reduction in delivery delays during the same six-month period.
  3. C
    The autonomous electric vans cost 30 percent less to maintain annually than conventional gas-powered delivery vehicles.
  4. D
    Surveyed customers in City Y expressed high satisfaction with the company's transition to environmental zero-emission vehicles.
  5. E
    The autonomous delivery vans occasionally required intervention from remote human operators during severe weather events.

Cevap

The statement that City Y experienced no major changes in traffic congestion, road construction, or total parcel volume during the six-month period provides the strongest support for the conclusion.
The correct answer strengthens the argument by ruling out potential confounding factors (such as decreased traffic or reduced package volume). If traffic and workload remained constant, it becomes significantly more likely that the new autonomous vans were indeed the factor responsible for the reduced delivery delays.

Adım Adım Çözüm

1
Identify the conclusion and premises of the argument.
Premise: Delay times dropped after introducing autonomous vans. Conclusion: The autonomous vans caused the reduction in delays.
Understanding the precise causal claim (autonomous vans -> reduced delays) is essential to strengthening it.
2
Determine what assumptions or vulnerabilities exist in the causal argument.
The argument assumes that no other external factor (like lighter traffic or fewer packages) caused the delay reduction.
In Causal Strengthening questions, ruling out alternative potential causes solidifies the author's proposed cause.
3
Evaluate the options to find the statement that eliminates alternative causes.
Confirming that traffic, roadwork, and parcel volume remained stable eliminates potential confounding variables.
If external conditions remained unchanged, the introduction of the autonomous vans stands as the primary difference responsible for the outcome.
