Zorluk: OrtaStrengthening Arguments

Urban planners monitored residential neighborhoods that planted dense rows of broadleaf deciduous trees along high-traffic arterial avenues. Over a five-year period, these neighborhoods experienced a 14 percent reduction in ambient daytime temperatures and a significant decrease in heat-related emergency room admissions compared to adjacent neighborhoods that installed reflective cool roofs. The planners concluded that the temperature reduction achieved by the tree canopies was directly responsible for the decline in heat-related emergency room visits. Which of the following statements, if true, provide additional support for the urban planners' conclusion? Select all that apply.

  1. The decline in heat-related emergency room admissions in tree-canopied neighborhoods occurred almost exclusively during peak afternoon hours when canopy shade and transpiration produced their greatest cooling effect.Cevap
  2. B
    Neighborhoods that installed reflective cool roofs experienced a simultaneous influx of elderly residents who are demographically more susceptible to extreme heat.
  3. Household air-conditioning capacity and resident access to emergency healthcare services remained equivalent across all studied neighborhoods throughout the five-year evaluation.Cevap
  4. D
    Substantial noise generated during the installation of reflective cool roofs caused acute stress-related health complications among nearby residents.
  5. E
    Deciduous trees shed their leaves during winter months, allowing greater solar radiation to heat building facades during cold seasons.

Cevap

The argument is strengthened both by establishing that emergency room visit declines coincided precisely with the peak hours of canopy cooling and by confirming that confounding factors like indoor air conditioning and healthcare access were equal across all neighborhoods.
The correct selections strengthen the argument in two complementary ways. First, showing that emergency room reductions occurred specifically during peak afternoon hours aligns the timing of the effect with the timing of maximum canopy cooling, reinforcing the causal link. Second, confirming that air-conditioning access and medical availability were uniform across neighborhoods rules out major potential confounding variables, ensuring the cooling effect itself accounts for the outcome.

Adım Adım Çözüm

1
Identify the core argument structure
Premise: Tree-canopied neighborhoods saw lower ambient temperatures and fewer heat-related ER visits than cool-roof neighborhoods. Conclusion: The canopy's cooling effect caused the decrease in heat-related ER visits.
Isolating the premise and conclusion clarifies the causal claim that must be strengthened.
2
Evaluate statements for strengthening mechanisms
Confirming that health improvements happened precisely when cooling was highest strengthens the causal link. Ruling out alternative explanations (such as baseline differences in air conditioning or healthcare access) confirms that the cooling effect was the decisive factor.
Causal conclusions are strengthened when alternate causes are eliminated or when precise dose-response timing is verified.
3
Eliminate options that weaken or introduce irrelevant information
Options introducing demographic shifts or installation noise provide alternative causes for the outcome difference (weakening the argument), while winter leaf shedding is irrelevant to summer heat emergencies.
Distractors often present alternate explanations or out-of-scope facts.
