What were some advantages of using rifles as a weapon in WW1?

Question

I only got some down, but I need at least 3-5 more.

Can fire many rounds in a minute, easy to bring and are lighter weight than most weapons, good portability, good range of up to 1400 meters

Answer 1

Are you sure rifles fire many rounds in a minute? I thought only machine guns could do that.
