Hannah is writing an essay about the human errors that were made during the Chicago fire of 1871. Several key human errors contributed to the spread of the Chicago fire of 1871. When the blaze first began, Bruno Goll refused to sound the first alarm, which was housed in his drugstore. Later, at the courthouse, Mathias Schaffer instructed his assistant, William J. Brown, to sound Box 342 instead of Box 319, sending firefighters toward the wrong location. When Schaffer realized his mistake, Brown flat-out refused to strike the correct box. Even after the fire, Brown was confident in his decision not to correct the mistake. Finally, as the blaze raged on, fireman John Dorsey attempted to sound a special alarm, but accidentally sounded a general alarm. This meant that additional trucks and equipment were not immediately sent out to help. Which is one extraneous detail from this passage? “Several key human errors contributed to the spread of the Chicago fire of 1871.” “Finally, as the blaze raged on, fireman John Dorsey attempted to sound a special alarm, but accidentally sounded a general alarm.” “Even after the fire, Brown was confident in his decision not to correct the mistake.” “When Schaffer realized his mistake, Brown flat-out refused to strike the correct box.”

The answer is C. I took the test. Just for fun, I will give you another answer.

Which revision is the best example of adding concrete detail?

Claire Innes became separated from her parents as the flames spread through the city, and she later found them.

Claire Innes was separated from the people around her during the fire and she later found them near the same place they were separated.

In the panic, Claire Innes was separated from her family as they fled, and she was reunited with her father after the fire was extinguished.

In the panic, Claire Innes became separated from her brothers and sisters during the fire and she later found them after the fire was put out.

The answer for THIS ONE is C as well.

I hope this helps

pepin the short[a] (german: pippin der kurze, french: pépin le bref, c. 714 – 24 september 768) was the king of the franks from 751 until his death. he was the first of the carolingians to become king.[b][2]

the younger son of the frankish prince charles martel and his wife rotrude, pepin's upbringing was distinguished by the ecclesiastical education he had received from the monks of st. denis. succeeding his father as the mayor of the palace in 741, pepin reigned over francia jointly with his elder brother carloman. pepin ruled in neustria, burgundy, and provence, while his brother carloman established himself in austrasia, alemannia and thuringia. the brothers were active in suppressing revolts led by the bavarians, aquitanians, saxons, and the alemanni in the early years of their reign. in 743, they ended the frankish interregnum by choosing childeric iii, who was to be the last merovingian monarch, as figurehead king of the franks.
