Study the velocity vs. time graph shown. A graph titled Velocity versus Time shows time in seconds on the x axis, numbered 0 to 6, velocity in meters per second on the y axis, numbered 0 to 9. A line starts at (0, 2) and ends at (6, 8).
What is the displacement of the object from 2 seconds to 6 seconds?

4 m
8 m
16 m
24 m

the answer is kevlar

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.
