In a passage about climate-resilient crops, which evidence would most strongly support the claim?

• A. Data showing higher yields under drought when using climate-resilient varieties.
• B. Anecdotal farmer testimonies only
• C. Historical crop prices only
• D. Satellite imagery of fields only

Answer: (A)

Direct, quantitative measurements that test the claim under the specific stress condition provide the strongest support. If you have data showing higher yields under drought when climate-resilient varieties are used, that directly links the intervention to the outcome and demonstrates performance in the challenging environment. Numbers allow you to compare results, assess statistical significance, and gauge how robust the effect is across different sites and seasons. Anecdotal farmer testimonies, while valuable for context, are subjective and limited in scope. They can be influenced by memory, bias, and non-representative samples, so they don’t establish a reliable general pattern. Historical crop prices reflect market factors rather than the crops’ biological performance under drought, so they don’t speak to resilience or yield outcomes. Satellite imagery can show patterns across fields, such as vegetation vigor, but imagery alone doesn’t prove that yields are higher under drought without accompanying yield data and controls for other variables. So the strongest evidence is the data that directly measures yield under drought for climate-resilient varieties, because it tests the core claim with objective, comparable outcomes.
