A student has a rubber band stretched across a box with a large hole, as shown in the image. The student is plucking the rubber band to make a sound. Which question would be best for him to use in a scientific investigation?

• How long and wide is the box?

• How much do the materials cost?

• How does the color of the box affect the pitch when plucked?

• How does the length the rubber band is stretched affect the pitch when plucked?
