Which of the following is NOT one of the three levels of questions?

The identification of "When" as not being one of the three commonly recognized levels of questions demonstrates a clear understanding of the framework for analyzing questioning techniques. Typically, the three levels of questions focus on the depth and cognitive engagement they require: "What" questions generally ask for facts or basic information; "How" questions delve into processes or explanations; and "Why" questions invite analysis and reasoning, exploring motivations or causes.

By this understanding, "When" does not fit into the same category as it pertains more to time-related inquiries rather than promoting deeper thought or engagement with the material. This distinction makes it clear why "When" is not considered one of the key levels of questioning that encourage critical thinking or exploration of concepts.
