An automated medical refrigerator monitors the storage of temperature-sensitive vaccines across two cooling chambers. The pseudocode below is designed to assign incoming vaccine vials to these chambers.

1  SET chamber1 TO ["", "", "", "", ""]
2  SET index1 TO 0
3  SET chamber2 TO ["", "", "", "", ""]
4  SET index2 TO 0
5  SET active TO True
6  SET stored TO False

34 [MISSING FUNCTION CALL]

The algorithm is incomplete.

• Line 8 should declare the function header (including name and formal parameters).
• Line 34 should assign the result of calling the function to the existing global variable stored, passing the correct arguments.
