Question

what does the word adjunct mean?
something that has harmful effects
something that provides evidence
something that comes before something else
something that is added to another thing

Explanation:

The term "adjunct" refers to something that is supplementary or added to another main thing, rather than being an essential part itself. The other options describe unrelated concepts: harmful effects relate to something noxious, evidence refers to proof, and a precursor is something that comes before another thing.

Answer:

something that is added to another thing
