Final answer:
The missing word in the context of thrilling audiences with daredevil maneuvers is 'Moves'. Moves correspond to the maneuvers meant to excite the audience, similar to those performed by an aviator like Quimby.
Step-by-step explanation:
The missing word in the sentence "She thrilled audiences with daredevil maneuvers, just as Quimby had done before her." is most likely D) Moves. This would be the appropriate word to describe the thrilling actions, such as the daredevil maneuvers mentioned, that are associated with someone like Quimby, who was known for her pioneering aviation feats. Moves in this context would refer to actions or maneuvers, particularly in aviation or performance, that are designed to excite and impress the audience. The sentence does not seem to describe flips specifically, story does not make sense in this context because it is not a maneuver, and lectures are more educational and unlikely to thrill audiences in the context of daredevil actions.
