You Look Outside and Realize That Your Grass Needs to Be

Multiple Choice

You look outside and realize that your grass needs to be mowed. You pick up the container of gasoline and see that you have approximately a third of a gallon left. You hypothesize that this amount will be enough to mow your entire lawn. Unfortunately, half way through mowing your lawn you run out of gasoline. 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 of future gas needs is based on experimental data and therefore increases the validity of your hypothesis.
B) Your prediction proved that your hypothesis is correct.
C) Your hypothesis was supported by trial and error. One more trial added to your data set.
D) The hypothesis was invalidated by your experimental evidence.
