suppose that you want to take a photograph of yourself as you look at your image in a flat mirror. The mirror is 5.45m away from the camera. for what distance should the camera lens be focused?

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

i believe the answer is a hope it and is correct
