Why do warehouse workers move heavy boxes around on carts with wheels?  

We know that sliding require more force that rolling

because in rolling friction is very less

as small portion of surface are in contact so the experience less friction than sliding

so it is easy to roll an object than sliding the same mass

that is why we use round shape wheel

which is easy to move

and because of that we use cart with wheel to move heavy loads

we can carry heavy loads easily in carts

if we try to lift it or slide, it needs more work to be done

but in cart we can carry heavy loads easily

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.
