What was the result of the stalemate that developed on the western front?

The correct answer is the following.

The result of the stalemate that developed in the Western front during WW1was that this Western front remained static, killing many soldiers of either side but not real progress at all. It resulted in so much attrition. Both sides tried to wear the opponent down killing as many soldiers as possible. This resulted in a stalemate in the trenches, no progress to either side. Such as a deadlock that stayed for a long time.
