The data suggests that the biological activity of the protein was reduced after the sample was treated with urea, indicating that the protein's three-dimensional structure was disrupted. Amino acids buried in the protein's interior are typically responsible for stabilizing its three-dimensional structure, while amino acids on the surface of the protein tend to be involved in interactions with other molecules. The fact that the protein's biological activity was reduced after treatment with urea suggests that the amino acids critical for stabilizing its structure were indeed on the protein's interior.
