What term is used to describe the action of finding a solution to a problem?

The term "figure it out" effectively describes the action of finding a solution to a problem as it conveys the process of reasoning or deducing an answer through thought or analysis. When faced with a challenge or dilemma, to "figure it out" involves critical thinking and problem-solving skills. It encapsulates the proactive exploration of options, experimentation, or calculations needed to arrive at a resolution.

In contrast, other choices do not capture this specific action: "clarify" refers to making something less confusing or more understandable, "summarize" involves condensing information into a shorter form, and "defend" means to support a claim or position, which does not directly relate to solving a problem. Therefore, "figure it out" is the most appropriate definition when discussing the act of finding a solution.
