My friend Davi posted a mini-rant on Facebook:
"I get really annoyed every time the PBS Kids lady asks "which of the four animals is different" from the other three and the choices are snake, whale, wolf, and elephant. She says snake because the rest are mammals, but the answer could just as easily be whale since the other three live on land."
Davi is correct--"whale" is the correct answer--although whales' inability to live on terra firma is not the only reason. Allow me to prove why this is so.
Take the numerical values for each animal's name based on their order in the English alphabet, and add the numbers of each name.
S: 19 W: 23 E: 5 W: 23
N: 14 H: 8 L: 12 O: 15
A: 1 A: 1 E: 5 L: 12
K: 11 L: 12 P: 16 F: 6
E: 5 E: 5 H: 8
+_____ +____ +____ +____
50 49 81 56
Then take the factors for each sum, and add them.
1,2,5,10,25,50 1,7,49 1,2,9,27,81 1,2,4,7,8,14,28,56
Sum: 93 Sum: 57 Sum: 120 Sum: 120
Then take the square root of each factor's sum:
Sq. Rt.: 9.64365076 Sq. Rt.: 7.6 Sq. Rt.: 10.95445115 Sq. Rt.: 10.95445115
...and you are presented with the startling evidence that three of the animals have square roots that end with values in the hundred millionth digit, although "whale" has a value of only 7.6, which ends in the tenths. CLEARLY this means the whale is, in fact, the different choice--not the snake.
I should also point out the fact that "elephant" and "wolf" both have the same factor-sum (120), and therefore the same sum square root value, which is numerical proof that they are basically the same animal.
So, PBS, as the Dowager Countess would say, "Put that in your pipe and smoke it."
