Answer:
B) Styrofoam is a good insulator.
Explanation:
When talking about thermal energy, or a heat, insulator is a material that doesn't allow heat to pass through easily. On the other hand, a conductor is completely the opposite, it allows, quite successfully, transfer of the heat.
So, regarding ice cream, from these definitions above, we can conclude that insulators will prolong melting time, while, in the conductors, ice cream will melt rather fast.
Looking at the table, we see that Styrofoam had the longest melting time, which makes it quite successful insulator.

Answer:
Bakers use yeast as a leavening agent in baking bread and other bakery products.
The yeast ferments the sugar present in the dough and converts it into ethanol and carbon dioxide.

Carbon dioxide causes the dough to rise whereas alcohol or ethanol formed usually evaporates during the baking process.
Thus, the given blanks can be correctly filled up by alcohol fermentation and carbon dioxide.
