Answer:
1) Analogy.
Step-by-step explanation:
An analogy is the use of comparison between two or more things with each other for the purpose of clarifying or giving an explanation. It provides similar aspects of the compared things or ideas.
In the given passage, Olivia is compared to a field general who's giving a speech to inspire and imbibe confidence in her team. This is an example of making an analogy with Olivia and a general, with both being leaders and inspiring their 'men' with the confidence they'd need to carry on in their work.
Thus, the correct answer is the first option.
