Question 8

A meteorology program uses the following algorithm to categorize wind speed readings in knots.

Figure 1

1      ws ← USERINPUT
2      IF NOT(ws < 35) AND ws MOD 2 = 0 THEN
3          OUTPUT "Gale"
4      ELSEIF ws >= 15 AND ws < 25 THEN
5          OUTPUT "Breeze"
6      ELSEIF ws MOD 4 = 0 THEN
7          OUTPUT "Calm"
8      ELSE
9          OUTPUT "Squall"
10     ENDIF

Which wind speed value input by the user would result in "Calm" being output by the algorithm?
