Structural analysis involves breaking down words into their component parts, such as prefixes, roots, and suffixes, to determine their meanings. In the case of "impassable," this word can be deconstructed into "im-" (a prefix meaning "not"), "pass" (the root word), and "-able" (a suffix meaning "capable of"). Together, these components help convey the meaning that something cannot be passed through, emphasizing the utility of structural analysis in understanding the term.

While the other words also have distinct meanings, they do not lend themselves to the same degree of analysis through their structural components. "Elephant," for example, does not break down into smaller meaningful parts that help indicate its definition. "Interim" and "examine" can also be understood at face value without a thorough analysis of their components. Thus, "impassable" stands out as the best choice for employing structural analysis to ascertain meaning.
