Based on what you know of the reproduction right (Section 106(1)), do the following fall within (and thus infringe) that right for a book's copyright owner?

1. I read the book aloud to you.

2. I write out the words from the book in sand on the shore; waves immediately wash them away.

3. I write out the words on the sidewalk in chalk.

4. Using an (analog) overhead projector, I show the book on the wall at the front of the room.

5. I store the book's text in encrypted files that can only be decoded with a special computer.

6. I make only a single copy of the book.
