The answer is: <u>B) The horse's mane was coarse and needed to be conditioned and brushed.</u>
Explanation:
Although you didn't provide any <em>italicized</em> word, I could easily spot the mistakes in the rest. Letter A, the noun should be "cOurse" as a programme of study and not "coArse" as and adjective meaning rough. Letter C. should be "seAm" as a stitched join, and not "seEm" as the intransitive verb, on the contrary to letter D which needs to have the verb "seEm" instead of the noun which means a "stitched join". Letter B is completely right, "mane" meaning the horse´s long hair.
The tone is dispassionate. Specific words would be cold, dead. The tone impacts my overall understanding by me getting to experience what it felt like somewhat to be a soldier suffering through all this horror.
