In the sentence provided, the word that BEST tells what Sue Ann did to the door is "closed." Here's why:
1. The sentence mentions that Sue Ann "closed the door when she left the room." This indicates that Sue Ann shut the door as she was leaving.
2. The word "banged" implies a forceful or loud closing of the door, which may not necessarily be the case based on the context given in the sentence.
3. The word "bumped" suggests a light or accidental impact, which doesn't fit the scenario of Sue Ann intentionally shutting the door.
4. The word "pushed" implies moving the door by applying pressure from one side, but in this context, Sue Ann likely used this action to close the door rather than pushing it open.
Therefore, based on the sentence provided, the most appropriate word to describe what Sue Ann did to the door is "closed."
