A researcher argues that a new fertilizer increases crop yield, pointing out that a farm using the fertilizer saw a 20% increase in corn production this year.
Which of the following, if true, identifies a flaw in the researcher's reasoning?
- No fertilizer of any kind has ever been shown to affect a farm's corn yield in a measurable way
- The farm reduced the total acreage that it planted with corn during this same year
- The farm also experienced unusually favorable weather conditions that were not present in previous years
- Corn production in several of the neighboring counties also rose by roughly 2% over this same period
- The farm intends to apply this very same fertilizer product to its own wheat crops the next planting year too
