So I don’t know much about this book, but I can help you with formatting. You should start of with a introduction. It should be catchy to grab the readers attention. U should probably look for a fun fact about Sonia. Then you have 2 body paragraphs. The first one should be about the biography. The second about the editorial. 
Next, you should have your comparing part. You can use quotes ext. 
last, you should have a conclusion. This is a summary of the essay to wrap everything up. You can tie it back with your fun fact in the intro. 
To check your grammar, you can use mugshots from the internet. (It’s a writing tool not a prison picture)
You can also use Gramarly to help you when you write. 
If you still have trouble, I recommend using essaytyper.com.

No because there is heavy rehtoric alluding to communist propaganda and ways of governing. especially the use of the word "comrade," in its essence, the entire story is just a parallel to the system of government during the Russian Revolution
        
             
        
        
        
It would be B. in my opinion
