Question

add or remove commas, if necessary, until the sentence has correct punctuation. from the top floor of the office building astrid hofferson could see the entire city.

Explanation:

The sentence "From the top floor of the office building Astrid Hofferson could see the entire city." needs a comma after "building" to separate the prepositional phrase (adverbial of place) from the main clause. This helps in clarifying the structure, showing that "From the top floor of the office building" is the introductory phrase, and then the main subject and verb ("Astrid Hofferson could see...") follow. So the corrected sentence is "From the top floor of the office building, Astrid Hofferson could see the entire city."

Answer:

From the top floor of the office building, Astrid Hofferson could see the entire city.
