How did the Battle of Verdun and the Battle of the Somme symbolize modern war’s destructiveness?

Verdun and the Somme were marked by enormous casualties and only small territorial changes. At Verdun, neither side gained a decisive advantage, while the Somme offensive produced limited gains at tremendous cost. This shows how modern weapons and mass armies could cause widespread death without meaningful progress, so the best choice is “Both battles caused many deaths but achieved very little or no progress for either side.”
