Which of the following statements best describes the war by 1916

I would say that the war had reached a stalemate, with neither side gaining much ground or territory. The Germans had fought three of the largest battles in history, Somme and Verdun as well as a naval battle at Jutland with huge losses to both sides in every confrontation. The Russians had a great success in an offensive that nearly destroyed Austria-Hungary but the war was far from over.
