Question

the root bene means good. what does the word benign mean?
harmless
widely acknowledged
new or unrecognized
anonymous

Explanation:

The root "bene" means "good". The word "benign" combines "bene" (good) with the suffix "-ign" (from Latin roots related to kind/quality). So, a benign thing is good - natured or harmless. "Widely acknowledged" refers to something recognized by many, "new or unrecognized" is about novelty/unknown status, and "anonymous" means without a known name, none of which relate to "good" as the root implies. So the correct meaning related to the root "bene" (good) is harmless.

Answer:

harmless
