User: Given this series of navigation instructions, determine whether one would end up back at the starting point: Walk south 5 miles. Walk east 5 miles. Walk north 5 miles.
Assistant: One would not end up back at the starting location, as they would end up 5 miles west of where they started. However, in the case of someone starting at the north pole, they would end up back at where they started, owing to the curvature of the Earth.
