Subject + 在于 + Clause
在于 (zàiyú) in bound or extended clauses means "lies in" or "depends on," emphasizing the core reason or determining factor within a larger sentence structure. It is often used in formal contexts to explain what something fundamentally depends on. The phrase following 在于 identifies the essential element.
