Answer :
The correct answer is "White turned the wagon around and again headed south, his family and all of his servants safely onboard."
Explanation:
Individual stories tell the experiences of a particular person, usually, about important events. From the options, the quote that is part of a particular story about the 1871 Chicago Fire is "White turned the wagon around and again headed south, his family..." because this tells the personal reaction and experience of a man in the fire. Also, other options only tell facts or general statements rather than particular experiences, an example of this is "The demand for carpenters and bricklayers soared".
