This question should have less time limit - then it will force people to take the heuristic approach - of a quick 2 minute evaluation comparing the numbers of alphabets, and some common alphabets inside the three words, and their relative positions, and arrive at the answer "C" with a high degree of confidence. Allowing them more time, they tend to try to do computation, then half way through most of them will give up, then turn to their teammates for the answer... Just like the Chinese proverb : one monk will have water to drink, a group of monks then nobody get to drink any water mentality
