Linux True and False Questions (make)

Please Answer True or False with a simple explanation

1. If a Makefile has 3 targets called target1, target2, target3 in that order, it is possible to run the command: make target2 (T/F)

2. make is useful in software development / coding projects only (T/F)

3.

Assume there is a subdirectory called backup in the current directory, and all other files in the current directory are C files. The Makefile rule: clear: @mv *.c backup

will produce an error because there is no @mv command (T/F)
