PICTURE THE SCENE: you’re stranded in a rainforest and you’ve just been poisoned by a mushroom.
The only hope you have of surviving is to drink an antidote produced by a certain species of female frog.
The catch is that the male and female look identical, though the male has a distinctive croak.
There’s a frog on a tree trunk to your left but, before you start running to it, you see two others in a clear to the right. One of them is croaking but you don’t know which.
You start to lose consciousness and realise you only have time to head in one direction before you collapse.
So, will it be right or left? Ted-Ed explains.
