To determine the best placement for the sentence "An injured armadillo slowly tries to make its way to safer ground with its head down," we need to consider the context of the surrounding sentences in the essay.
If the surrounding sentences describe themes of struggle, resilience, or metaphorical imagery that aligns with the injured armadillo's situation, then the placement could enhance the meaning of the text.
Without specific excerpts from "Peaceful Protest Through Metaphor," it's challenging to pinpoint the exact placement. However, generally speaking, if the preceding sentences discuss themes of struggle or convey a sense of hardship, a logical placement for the new sentence could be D. after sentence 8, where it might effectively illustrate the metaphorical message of peaceful protest through the imagery of the armadillo.
Please consult the essay to determine the context of each sentence and to see where the new sentence aligns most closely with the overall message.
