Test your skills of deduction with the September 2021 edition of Riddle Me This: Two Tree and An Island
You are standing at the edge of a lake. The lake is five hundred feet in diameter and there is a small island directly in the middle. There is a large tree next to you, and a large tree in the middle of the island. You cannot swim and you have a little over five hundred feet of rope. How can you use the rope as a means to get to the island in the middle of the lake?

Tie the rope to the tree beside you, Walk around the lake, carrying the free end of the rope, until directly across from the tree with the rope tied to it and the island between you and the tree. Use the rope to pull yourself across the water to the island.
Easy Peasy! Tie one end of the rope to the tree on shore, then walk to the opposite shore so that the rope crosses by the tree on the island. Secure the remaining rope end to the shore opposite the tree on shore. Then use the rope as a means to pull yourself to the island from shore.
The two previous answers would work but I have a slightly different answer. Since the lake is 500 feet in diameter and the rope is slightly longer than 500 feet, you can tie one end of the rope to the tree on the shore then walk completely around the lake carrying the rope with you. When you get back to the place you started, tie the other end of the rope to the same tree on the shore. Since the rope is now between the two trees, you can use the rope to pull yourself over to the island.
