complete the sentence with a word that means the same as significant.
the success of the year - long protest in montgomery was │, because it showed that peaceful protests could lead to change.
options: important, lengthy, difficult, confusing

Explanation:

To solve this, we analyze the meaning of "significant" in the context. The sentence explains the protest's success showed peaceful protests lead to change, so we need a synonym for "significant" (meaning important). "Important" matches as "lengthy" refers to duration, "difficult" to ease, and "confusing" to clarity—none fit like "important".

Answer:

important
