Answer
The line where selection is first used is Line 2, as this is where the first IF condition appears.

Answer
The line where iteration is first used is Line 11, as it is where the FOR loop starts.

Answer
The subroutine DISPENSE_BISCUIT would be called 1 time because when the input is 'breakfast', q is set to 1.

Answer
The data type of the variable time is String, as it stores text inputs like 'breakfast', 'lunch', or 'dinner'.
Step 5
State how many times the subroutine DISPENSE_BISCUIT will be called with the parameter 'chewies' if the user input is 'lunch' in Figure 2.
