Final answer:
The author's tone becomes more somber in paragraphs 27 and 28.
Step-by-step explanation:
The answer is b) The author's tone becomes more somber in paragraph 27 and remains somber in paragraph 28. In order to determine the tone of a passage, we must analyze the author's word choice and overall writing style. In paragraphs 27 and 28, the author's tone becomes more serious and mournful, using words and phrases that convey a sense of sadness or seriousness. This shift in tone can be seen through the use of words like 'tragic,' 'grief,' and 'heartbreaking,' which indicate a more somber tone.
