Question

marshall made a batch of bread dough and divided it into two balls of equal size. he measured the sizes of the dough balls and placed one in an 80°f warming cabinet and the other in a 60°f warming cabinet. the cabinets each had 75 percent humidity. marshall let the dough expand in the warming cabinets for two hours. leaving the dough on the pan, he then measured the sizes of the dough balls and calculated how much the dough had expanded. marshall repeated this process with nine more batches of bread dough, alternating which warming cabinet was set to 60°f.
identify the question that marshalls experiment can best answer.
is bread dough that expands at 80°f stretchier than bread dough that expands at 60°f?
does bread dough expand more at 80°f compared to 60°f?
does a humidity level of 75 percent cause bread dough to expand more than a humidity level of 60 percent?

Explanation:

Marshall varies the temperature between 60°F and 80°F while keeping humidity constant and measures dough expansion. So the experiment is about the effect of temperature on dough expansion.

Answer:

Does bread dough expand more at 80°F compared to 60°F?
