Write a single paragraph on the importance of communication and underline the topic sentence​

I'll try

Explanation:

Communication is important because it allows for spreading of news, especially during emergencies during the olden or early days. When someone was in danger or lost, the would build a fire and let the smoke signal for help if seen.

with whom will you be coming to the party? this is written correctly.

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.
