Answer:
I believe the phrase that best reflects the excerpt's passionate tone is:
“enforce her tyranny”
Step-by-step explanation:
The author is exposing how Britain has oppressed the colonists. However, he does so in a passionate way, which is conveyed by his tone. Tone is how an author approaches a topic, his attitude towards what is being discussed, and it is conveyed through word choice. Therefore, when the author says "her tyranny," he is using a strong word that helps convey the way he feels. It wouldn't have been the same if he had said, for instance, "her power". Power can be used for good as well as for bad. Tyranny already conveys the idea that absolute power is being used for bad, that oppression and repression are constant, that cruelty is being employed.
