Answer
The correct line number where selection is first used is Line number 2. This line implements the first IF statement to check the time.

Answer
The correct line number where iteration is first used is Line number 11. This line introduces a FOR loop that iterates through a specified range.
Step 3
State how many times the subroutine DISPENSE_BISCUIT will be called with the parameter 'chewies' if the user input is 'lunch'.
