Question

63. A student wanted to determine if slugs preferred green leaf lettuce
leaves over purple cabbage leaves for food. Pieces of both leaves
were cut. One piece of each type of leaf and one slug were placed in
each often containers. After three days, the surface area of each leaf
section was measured and the results were recorded in a data table.

• The time interval was not recorded when the slugs were placed.
