Engineers are investigating the properties of a material for use as a wrapping product. Three identical sheets of the material are placed in different temperature water baths. A 20 g weight is attached to the
bottom of each sheet and the amount each sheet stretches is measured. The results are in the table.

Which conclusion about the material is supported by the data in the table?
A. The molecules in the material shorten when they become hotter
B. The molecules in the material shorten when they become colder
C. A warm sheet of the material will break under less stress than a cold rubber band will
