Agricultural Economist: In 2024, the nation of Oakhaven banned the import of proprietary autonomous agricultural drones, prompting domestic farmers to adopt locally manufactured, open-source drones instead. Over the subsequent two years, agricultural yields in Oakhaven increased by 15%, and the average annual cost of farm maintenance dropped substantially. Clearly, the shift to open-source, locally manufactured drones is more efficient for Oakhaven's agricultural sector than relying on imported proprietary models.

Which of the following statements, if true, independently strengthen the economist's argument? (Select all that apply.)

  1. Weather patterns, soil health metrics, and seed varieties utilized in Oakhaven over the past two years were virtually identical to those in the two years immediately preceding the 2024 ban.Cevap
  2. The previously imported proprietary drones required shipping to foreign facilities for routine servicing, causing prolonged downtime during critical harvests, whereas open-source drones are rapidly serviced on-site using locally 3D-printed parts.Cevap
  3. C
    Concurrently with the drone import ban, Oakhaven's agricultural ministry implemented a comprehensive initiative that provided farmers with heavily subsidized, high-yield synthetic fertilizers.
  4. D
    All technological transitions from proprietary hardware to open-source manufacturing models inherently result in increased operational efficiency across every sector of a national economy.
  5. E
    Prior to the 2024 ban, domestic farmers in Oakhaven relied exclusively on imported proprietary autonomous agricultural drones to manage their crop yields.

Cevap

The statements ruling out alternative environmental causes for the yield increase and detailing the localized, faster repair mechanism.
The argument concludes that open-source drones are more efficient based on two observed phenomena: a 15% yield increase and a drop in maintenance costs. The correct answers bolster this causal claim in two distinct ways. The first correct statement eliminates alternative explanations for the yield increase by confirming that weather and soil factors remained constant, meaning the drones are highly likely to be the catalyst. The second correct statement provides the missing mechanical link for the cost drop by contrasting the efficient on-site repair of the new drones with the prolonged, expensive foreign shipping required by the old proprietary models.

Adım Adım Çözüm

1
Deconstruct the argument's core structure.
Premise: Switched from proprietary to open-source drones. Premise: Yields increased 15% and maintenance costs dropped. Conclusion: Open-source drones are more efficient.
Identifying the premises and main conclusion is strictly necessary to precisely evaluate the logical gaps.
2
Identify logical vulnerabilities and causal assumptions.
The argument assumes that the new drones actually caused the yield increase (ignoring weather/fertilizer variables) and that the new drones are responsible for the cost drop (ignoring potential shifts in subsidy or labor).
Strengthening an argument typically involves identifying and systematically patching these specific vulnerabilities.
3
Evaluate the options against the identified vulnerabilities.
One correct statement explicitly eliminates alternative variables (weather, seeds) for the yield spike. The other correct statement explains exactly how the new drones lowered costs (on-site repair vs. foreign shipping).
Options that rule out alternate causes or explain the causal mechanism directly increase the overall plausibility of the conclusion.
