Transcript text: Does bread dough expand more at $80^{\circ} \mathrm{F}$ or at $60^{\circ} \mathrm{F}$ ? Is bread dough that expands at $80^{\circ} \mathrm{F}$ stretchier than bread dough that expands at $60^{\circ} \mathrm{F}$ ? Does a humidity level of 75 percent cause bread dough to expand more than a humidity level of 60 percent?

Solution

Solution Steps

Step 1: Understand the Experiment

Larry conducted an experiment to observe the expansion of bread dough at two different temperatures, 80°F and 60°F, with a constant humidity level of 75 percent. He measured the expansion of the dough after two hours in each temperature setting.

Step 2: Identify the Main Question

The experiment aims to determine the effect of temperature on the expansion of bread dough. The primary question that the experiment can best answer is:

Does bread dough expand more at 80°F or at 60°F?

Step 3: Analyze the Options

Does bread dough expand more at 80°F or at 60°F?
- This directly relates to the experiment's setup and purpose.
Is bread dough that expands at 80°F stretchier than bread dough that expands at 60°F?
- This question is not addressed by the experiment, which only measures expansion, not stretchiness.
Does a humidity level of 75 percent cause bread dough to expand more than a humidity level of 60 percent?
- This question is irrelevant to the experiment since the humidity level was constant at 75 percent.
