The amount of energy it takes to lift a box might be a function of which of the following?

a. the time of day that you are lifting it
b. the weight of the objects inside the box
c. the shape of the box

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 think it would be 5
