Sanitation
With the rapid influx of people into New York City, sanitation would be a major issue for people living in New York City in the mid-to late 1800s. Proper sanitation is a need because without it disease is easily spread. Overpopulation creates a strain on any sanitation system, and in the mid to late 1800s, there was really no system for sanitation in New York City. All of the other options were not a major issue for people during this time period as they were not seen as necessities, only luxuries.
To grab attention of the readers, the poets, authors and writers use techniques that let those words stay in the minds of the readers.
Explanation:
One of the techniques which is frequently used and which can be often observed in our everyday lives - news, movies, entertainment sector - is Alliteration.
The similar sound of the initial words/first letter in a line/sentence is alliteration. When there is repetition of the letter that produces the same sound while pronouncing, it creates a pattern in how we understand that sentence.
Here, 'float free' is an example of alliteration - <u>f </u>loat <u>f </u>ree - similar sound of initial words. In alliteration, the words of which first letters are repetitive and have a similarity in sound are always consonants.
