One reason the third reich was effective was because it
encouraged couples to have fewer children.
trained both men and women for military service.
came to power at a time when employment was high.
used propaganda to encourage nationalism and obedience.

The correct answer is the third one: the Third Reich used propaganda to encourage nationalism and obedience.

The Third Reich propaganda, conducted by the Minister of Propaganda Joseph Goebbels, was one of the most successful cases of political communication of the 20th century. It was very effective among the German population by using excellent oratory tools and appealing to irrational feelings like an exacerbated nationalism, feeling of belonging to a superior community, antisemitism, racism, and an extreme hatred towards communists and foreigners in general. By invoking the hatred of the masses towards a foreign enemy, encouraging nationalism, and silencing opponents the Third Reich was able to conduct the population and easily enforce obedience to the government among the citizenship.
