Design used a plastic cover for her backpack → it looked neat - evidence: she liked the color and carried it to school.

Design was heavy like a rock so rain could not enter → backpack stayed dry - evidence: the cover felt heavy in her hands.

Design kept the backpack dry because plastic exists → problem solved - evidence: she used it once and hoped it worked.
