To determine if two subsets of the Euclidean space are open, we must first understand the definition of an open set. A subset of the Euclidean space is said to be open if for every point in the set, there exists a real number such that every point that satisfies |x - y| < is a member of the set.

Okay, so I need to design a problem based on the given external knowledge about open sets in Euclidean space. The problem should be challenging, well-structured, creative, and have a single numerical answer. Let me start by recalling the key points from the external knowledge.
