Answer 1

Answer: Traditional weapons were not successful in trench warfare.

Explanation: Because soldiers were hiding away in trenches and not in direct sight of one another, both sides needed a weapon that could infiltrate into the opposing sides' trenches. As gas attacks could do incredible damage with little to no losses for the side using it, they became increasingly popular.
