If someone is "stupefied," what does it mean?

Being "stupefied" refers to a state of being so shocked, confused, or astonished that one is unable to think clearly or respond appropriately. When someone is stupefied, their mental alertness is significantly diminished, which aligns well with the notion of being made "less alert."

The term originates from the word "stupefy," which means to dull the senses or to make one unable to think or act normally due to overwhelming circumstances or stimuli. This is why the understanding of the term suggests a lack of clarity and a decrease in cognitive function.

Other choices reflect actions or states that neither relate to confusion nor a lack of mental sharpness, thus reinforcing why the correct interpretation focuses on the diminished alertness associated with being stupefied.
