Question

ethiopia has never been colonized by another country. it was occupied by italy from 1936 to 1941. however therefore ← joining words
revise your work. look at the hint, and try using a semicolon to join the ideas.

Explanation:

The two sentences present a contrast: one states Ethiopia was never colonized, the other that it was occupied by Italy. "However" is a conjunctive adverb for contrast. Using a semicolon and "however" (with a comma after) connects the ideas. So the revised sentence is: Ethiopia has never been colonized by another country; however, it was occupied by Italy from 1936 to 1941.

Answer:

Ethiopia has never been colonized by another country; however, it was occupied by Italy from 1936 to 1941.
