Answer: question 4: third person.
question 2: b, he is traveling north
Explanation: well think about how the story is talking to you, is the frog telling the story? no. is the scorpian telling the story? no therefor its a narrator telling the story. and the point of this story is all about how the scorpian can't swim so he asks for the frogs help. however the frog is worried because the scorpian has a deadly sting. and the reason the scorpian has to ask the frog for help is because he needs to cross the river so through process of elimination we see that the only answer that isnt important to the story is b, he is traveling north.
