2 (1 point) Sam has written a really good, best-selling detective novel. Two years later Bill also writes a detective novel.

Which of the following is true: Sam has a copyright over the ideas contained in his novel, and can sue Bill for copyright violation; Bill will be liable to Sam for the tort of plagiarism; Bill can do nothing as novels are not protected by copyright; Sam can do nothing because copyright protects the form of the work but not the ideas contained in it
