Answer:
The percentage of people who did not vote for the Nazi Party.
Explanation:
This is the information that would most support the argument presented in this passage. In this text, we are told that Hitler was granted sweeping powers by the Parliament even though most Germans never voted for him. However, we are not given the actual number of people who did not vote for him. Having this information would prove very useful, as it would give us a better idea of Hitler's popularity among the German people.
