Question 28

In an automated environmental monitoring system, the carbon dioxide level, $C$ (in ppm), is processed using the algorithm below:

1      C ← USERINPUT
2      IF NOT(C <= 12) AND C MOD 5 = 0 THEN
3          OUTPUT "Critical"
4      ELSEIF C * 3 < 40 OR C MOD 4 = 2 THEN
5          OUTPUT "Warning"
6      ELSEIF NOT(C < 10 OR C > 20) THEN
7          OUTPUT "Normal"
8      ELSE
9          OUTPUT "Standby"
10     ENDIF

If the user input for $C\,$ is 14, what will be the output?
