Answer:
(E) all of the above
Explanation:
Suspicion of the loyalty of German-Americans (and Dutch, Swiss, and
other European-Americans confused with Germans) was widespread in the
U.S. and resulted in a number of anti-German actions, including banning
of German language instruction in schools, renaming sauerkraut "liberty
cabbage," book-burnings, and mob violence, including a lynching of a
German-American in Illinois who was accused of making disloyal remarks.
The Committee of Public Information, led by George Creel, published
inflammatory anti-German posters to sell Liberty Bonds and encourage
army recruitment.
