Researching this Frog

A prominent scientist conducted very important experiment.

He trained a frog to jump upon giving it a verbal command ("Jump!").

In a first stage of experiment he removed frog leg, told it to jump, and the frog jumped.

So he wrote in his scientific notebook: "Upon removing one leg all frog organs function properly."


So, he removed the second leg, asked the frog to jump, it obeyed, so he wrote again: "Upon removing the second leg all frog organs function properly."


Thereafter he removed all the legs but one, the frog jumped when ordered, so he wrote again: "Upon removing three legs all frog organs function properly."


Then he removed the last leg. Told the frog to jump, and nothing happened. He did not want to take a chance, so he repeated the experiment several times, and the leg less frog never jumped.


So he wrote the conclusion: "Upon removing the last leg the frog loses sense of hearing"
