You grumble and think to yourself that the next time you mow the lawn, you hypothesize that you will need to have at least two-thirds of a gallon of gasoline available. How did the results of your lawn-mowing experience influence the validity of your new hypothesis for future gasoline needs?
A. Your prediction proved that your hypothesis is correct. B. Your hypothesis was supported by trial and error. One more trial added to your data set. C. The hypothesis was invalidated by your experimental evidence. D. Your prediction of future gas needs is based on experimental data and therefore increases the validity of your hypothesis.
