A student conducted an experiment to measure the germination rate of a specific seed variety at different temperatures. The following data was recorded: 10^circC | 25% germination 20^circC | 50% germination 30^circC | 75% germination If the student conducts a new trial at 25^circC, what is the most scientifically sound prediction for the germination rate?

1. The germination rate will be exactly 50% because 25^circC remains within the same biological thermal bracket as the previous 20^circC measurement trial.
2. The germination rate will drop to 37.5% due to the increased metabolic stress that results from exceeding the 20^circC threshold observed in earlier trials.
3. The germination rate will exceed 85% because biological processes typically accelerate exponentially as the environment approaches the optimal temperature range.
4. The germination rate will likely be approximately 62.5%, as the data suggests a linear relationship where the rate increases by 2.5% for every degree.
