Answer:
In Leni Riefenstahl's "Triumph of the Will" (1935), several cinematic techniques were used to promote Nazi ideology. The relevant techniques among the given options are:
c. Aerial views of the grand stage and crowds
d. Excited crowds appear to hear Hitler speak
e. Hitler is filmed from below
f. Hitler descends from clouds in a plane
These techniques helped to elevate Hitler's image and create a powerful, almost divine, portrayal of his leadership and the Nazi movement:
- **Aerial views of the grand stage and crowds**: This technique emphasized the scale and unity of the Nazi Party, showcasing its power and organization.
- **Excited crowds appear to hear Hitler speak**: This created an image of widespread enthusiasm and support for Hitler among the German people.
- **Hitler is filmed from below**: Filming from a low angle made Hitler appear larger-than-life, more powerful, and authoritative.
- **Hitler descends from clouds in a plane**: This symbolic entrance likened Hitler to a messianic figure descending from the heavens, enhancing his portrayal as a savior of Germany.
Options a (symbols like a rooster) and b (photomontage of posters and magazines of Hitler) are not notable techniques used in the film for promoting Nazi ideology.
