Problem: An inventor named Nelly is tinkering around in her home office where she has created two new types of material that could be used in products. The first one she is calling Glubber, and the second she has named Malk. To try to figure out what type of products these new materials may be used for, Nelly is performing various tests. The first test she is doing is securing one end of the material to a table and then pulling on it and letting it go. When she performs this test on some Glubber, the material quickly snaps back toward the table. Performing the same process with some Malk, the material slowly crawls along the floor as it makes its way back to the table. Which material is less resistant to changing shape?

A: Malk
