Question

question 2
using —————— will broaden your search.
plus
also
or
not

Explanation:

In search queries, the logical operator "OR" combines search terms to include results that match either term, thus broadening the search. "PLUS" (usually + in some search engines) is for including terms (narrowing in a way if used with other modifiers in some contexts but not the main broadener here), "ALSO" is not a standard search operator in this context, and "NOT" (usually -) excludes terms (narrowing the search).

Answer:

C. OR
