Zorluk: OrtaStrengthening Arguments

In an effort to increase agricultural production, an agricultural board in a drought-prone province advised tomato growers to replace conventional overhead sprinkler systems with subsurface drip irrigation, which delivers water directly below the soil surface to root zones. The board claimed that adopting subsurface drip irrigation will significantly increase average tomato yields per acre across farms in the province. The board reasoned that because subsurface drip irrigation minimizes surface evaporation, it ensures consistent moisture levels near the plant roots, which is crucial for healthy fruit development.

Which of the following, if true, provides the strongest support for the agricultural board's claim regarding tomato yields?

  1. Consistently stable moisture levels in the root zone prevent a soil-borne fungal infection common to the province that severely reduces tomato plant yields.Cevap
  2. B
    Subsurface drip irrigation lines in the province are uniquely prone to clogging by minerals present in local groundwater, frequently causing uneven water delivery across fields.
  3. C
    Tomato varieties grown in neighboring provinces produce significantly higher yields when cultivated in controlled greenhouse environments rather than open fields.
  4. D
    Overhead sprinkler systems consume considerably more electricity per hour of operation than subsurface drip irrigation systems do.
  5. E
    Several farms in the province that adopted subsurface drip irrigation reduced their overall annual water consumption by more than twenty percent.

Cevap

The statement that consistently stable moisture levels in the root zone prevent a soil-borne fungal infection common to the province that severely reduces tomato yields provides the strongest support for the argument.
The argument concludes that subsurface drip irrigation will increase tomato yields per acre because it maintains consistent root-zone moisture by preventing evaporation. The option stating that stable root-zone moisture prevents a common local fungal infection that severely reduces yields provides a concrete biological mechanism explaining WHY consistent moisture will result in higher yields, thus strongly reinforcing the conclusion.

Adım Adım Çözüm

1
Identify the main conclusion and core premise of the argument.
Premise: Subsurface drip irrigation minimizes evaporation and keeps root zone moisture levels consistent. Conclusion: Adopting subsurface drip irrigation will significantly increase average tomato yields per acre in the province.
Understanding the precise logical gap between consistent root zone moisture and increased crop yield is necessary to evaluate potential strengtheners.
2
Evaluate how an additional fact can bridge the gap between premise and conclusion.
If consistent root zone moisture directly prevents a prevalent local disease that normally cuts yields, then maintaining that moisture level will logically cause overall yields to increase.
A valid strengthening statement establishes a direct causal connection between the operational mechanism and the desired outcome.
3
Eliminate choices that weaken the argument, focus on cost/water savings, or introduce out-of-scope details.
Options raising concerns about system clogging weaken the claim; options discussing electricity or total water savings address collateral benefits rather than yield per acre; options discussing greenhouse farming in other regions are out of scope.
Only facts directly bolstering the mechanism driving higher crop yield per acre serve as valid strengthening evidence.
