question 20

Multiple Choice

Being a good steward of the environment, Rory had the unique idea of making the mesh biodegradable, so that when he replaces the mesh, he can just throw it away without harming the pristine environment around his cottage. There is, however, a problem with the mesh in that it biodegrades too easily. After a rainstorm or two, the mesh begins to disintegrate. Moreover, secretions from various bugs can have the same effect. Rory submits a patent for the biodegradable mesh screen designed to keep out bugs. Which of the following assessments is most accurate of his application?
