A gift awaiting you, if u can get dis 3 riddle correct

(1) The Farmer’s Challenge
A farmer went to market and purchased a fox, a goose, and a bag of corn (for reasons that must forever remain his own). On his way home, he needed to cross a river, but the boat he found there was so tiny, it could only carry the farmer himself and a single one of his new possessions. Naturally he couldn’t leave the fox alone with the goose; or the goose alone with the bag of corn. The only things he could safely leave together were the fox and the bag of corn, for a fox will never be tempted to eat corn, and only very rarely will a bag of corn be tempted to eat a fox. The farmer’s challenge was this: how could he ferry all of his possessions across the river, without harm coming to any of them?

(2) The Riddle of the Sphinx
What walks on four legs in the morning; three legs at midday; and two legs in the evening?

(3) The Labyrinth
Identical twins — A liar and a truth teller — stand at a fork of the path in a labyrinth. One path leads out of the labyrinth, but the other leads further into it, and following it would be illadvised to say the least. You do not know which of the twins is the liar and which is the truth teller, but you know that they both know the way out of the labyrinth and are aware of the other’s behavior.
You may ask only one question to only one of the twins. What should you ask to escape the labyrinth?

(3) The Labyrinth
Identical twins — A liar and a truth teller — stand at a fork of the path in a labyrinth. One path leads out of the labyrinth, but the other leads further into it, and following it would be illadvised to say the least. You do not know which of the twins is the liar and which is the truth teller, but you know that they both know the way out of the labyrinth and are aware of the other’s behavior.
You may ask only one question to only one of the twins. What should you ask to escape the labyrinth?

1. He carries the goose first to the other side of the river. He then carries the bag of corn to the other side but this time he brings the goose back. He then carries the fox to the other side of the river. Thereafter, he comes back to finally carry the goose back to the other side of the river.
2. Rephrase your question. Answer should be a human being(a baby in the morning, an adult in the afternoon and an old person in the evening).
3. I will ask one of them which is the way to escape the labyrinth and I will take the opposite direction he points. This number 3 is too hard.
