Final answer:
The word 'Miracle' implies that the success of the operation was highly unlikely and could be considered miraculous, pointing to the high chance of failure.
Option C is the correct option. It suggests the odds were high that the rescue operation could have failed.
Step-by-step explanation:
The author’s use of the word "Miracle" in Paragraph 3 of the text most likely impacts the tone by suggesting that the odds were high that the rescue operation could have failed.
The term "Miracle" often conveys a sense of wonder and improbability, indicating an event that goes beyond normal expectations or natural law. In the context of the passage, this use of the word may imply that a successful outcome was so unlikely that it could be considered miraculous, thus underscoring the difficulty and potential for failure inherent in the situation.
