Final answer:
Olivia is most likely to communicate her design and prototype to others, presenting the details and results of her tests, seeking feedback, and preparing for the competition.
Step-by-step explanation:
After building a prototype and conducting multiple rounds of testing and improvement, Olivia is most likely to proceed with the next step in the engineering design process, which is to communicate her design and prototype to others. This step involves sharing details about her automated fish feeder's design, the testing it has undergone, and how it meets the objectives of the competition. It provides an opportunity for feedback, which can be used to make any final adjustments before the competition. Communicating the design effectively is crucial for convincing judges or potential users of the value and functionality of her device.
