What is the point of having "normal" permissions that are given to any application without asking the user? (Mark all that apply.)

Note: Make sure you select all of the correct options—there may be more than one!

1. The device owner (user) can revoke a normal permission from an existing application, but still keep the application working
2. The device owner (user) can audit what applications have requested access to a particular normal permission
3. An application cannot inadvertently misuse normal permissions that it has not requested
