Question

1. general john j. pershing made a major contribution to the allied victory in world war i by transforming inexperienced troops into an effective military force developing advanced technologies for battlefield use requesting humanitarian aid from congress for war-torn countries negotiating the terms of the treaty of versailles

Explanation:

John J. Pershing was a military leader. His main contribution was in military organization. Transforming inexperienced troops into an effective military force is a key military - related contribution. Developing advanced technologies was more of an engineering/science - related (but not his main role). Requesting humanitarian aid was not his primary role. Negotiating the Treaty of Versailles was more of a diplomatic (politics - related) task not directly his major contribution to the Allied victory in terms of military operations.

Answer:

transforming inexperienced troops into an effective military force
