Like magic, it seemed to reveal itself from nowhere!
“Alfred Sewell ended his discussion of Chicago with a stirring prediction: ‘The city will nevertheless rise again, nay, is already rising, like the Phoenix, from her ashes. And she will, we believe, be a better city as well as a greater one, than she was before her disaster.’”
This is the best option because it gives the feeling of hope. The image of the Phoenix rising out of the ashes is meant to show that Chicago will once rise again. It will come back and be even better. The quote says that the city will "rise again" and "is already rising". Two of the other options only speak of the devastation of the fire. The option about the workers tells about the demand for laborers but it doesn't necessarily evoke a sense of hope in rebuilding.

I full-heartedly believe you should watch the Harry Potter films for multiple reasons; most of them being they teach you valuable lessons. For example, Harry Potter arrives Hogwarts and everybody is staring at him as if he were nothing but an object, however, Hermione Granger and Ron Weasley treat him like another person, which is what he wanted. Many purebloods, witches and wizards who contain no muggle (human) blood, treat muggleborns differently because of blood supremacy. Hermione Granger is a muggleborn and she was made fun of for it, and being smart. They form a friendship where it shows that no matter how hard things get, you have to be by each other’s sides, and communication is key. Another lesson it teaches you is to never take anyone for granted. There are numerous deaths in Harry Potter which I will not state here for your sake, but all of them teach you that anybody can be taken from you at any time, so you must live life to the fullest and love everybody. I would love to list every reason but this paragraph has gotten rather long, therefore I will end it and hope I have interested you enough.
