The term 'impede' means to obstruct or interfere with progress or movement. When something impedes a process, it creates barriers or challenges that prevent it from proceeding smoothly or quickly. This aligns perfectly with the definition of the word in context, as it emphasizes the notion of causing delays or hindrances.

In contrast, the other options reflect different actions that do not align with the meaning of 'impede.' To hasten an action suggests speeding something up, which is the opposite of impeding. Clarifying a point involves making something clear or easier to understand, rather than obstructing it. Analyzing thoroughly refers to examining something in depth, which does not involve the idea of obstruction or interference. Thus, the choice that accurately represents the meaning of 'impede' is the one that indicates obstruction or interference.
