Original fiction: The Shared Supply Shelf

The art club changed how it stored supplies. Labels showed where each kind of material belonged. A return box held items that needed sorting. A picture chart helped new members find tools. At the next meeting, members found the tape and brushes without asking three different people. The changes did not add new supplies; they made existing ones easier to find.

Question 1 What is the main idea?
Question 2 Which detail supports that idea?
Question 3 What was the return box for?
Question 4 What did the changes not do?
Question 5 Which title fits the whole passage best?
