2 European countries still held african colonies in 1914
it would have to be D.Zapata because Emiliano Zapata (1879-1919) was just the leader of southern peasants during the Mexican Revolution
The most correct option from those listed here is the second option: The assignment was originally due on Tuesday; however, the instructor changed the due date to Thursday.
The first and third options awkwardly have the word "however" capitalized in the middle of the sentence, and the last option uses the semicolon completely wrong (you're supposed to use it to connect two independent clauses).
Hope this helps. Do let me know if you have further questions.
