Wonderlic Cognitive Ability Practice Test – Prep, Questions & Study Guide

The correct answer is that the words "Optional" and "Observational" are not related. This means that they belong to entirely different concepts. "Optional" refers to something that is not obligatory, meaning it can be chosen or left out, while "Observational" pertains to the act of observing or having to do with observations or the act of watching. Since these terms address distinct ideas—choice versus the act of seeing—their meanings do not overlap or connect in a relevant way, making them unrelated in a semantic context.
