Thank you very much for your help. You really helped me to solve the situation with the essay. I had completely forgotten about it, and when I was reminded - to write it myself, there was no time. Well, that my order quickly responded to the authors. The author did the work, as promised, quickly - after 2 days, I handed the essay. I was afraid that the quality wasn't very good, but it turned out - for nothing. Everything turned out great. So, I am very grateful for your help.
