문제 9Last Saturday, Jimin visited the recycling center near her apartment with her science class.
(A) She had expected the place to be dirty and unpleasant, but the center looked clean and well organized. A worker named Mr. Park guided the students through each area, explaining how bottles, cans, and paper were sorted.
(B) He showed them a machine that crushed plastic bottles into small pieces before they were sent to factories. Jimin was surprised to learn that mixed trash, thrown into the wrong bin, often ruined an entire batch of recyclables.
(C) For example, one greasy pizza box could contaminate a whole pile of clean paper. However, when items were sorted correctly, they could be reused many times, almost like ingredients in a favorite recipe. Walking home, Jimin realized that her small effort at home truly mattered. She decided to sort her family's trash more carefully.
