One of the contributing factors to america's initial decision to enter into world war i was the zimmermann note. what were the contents of this telegram sent from germany? a. germany's proposal that upon an alliance with mexico, it would ensure the return of mexican land lost to the united states. b. germany's threat that upon a mexican-american alliance, it would no longer engage in trade activities with mexico. c. germany's insistence that the mexican government refuse to assist the allies with financial or military aid. d. germany's war secrets promised to the mexican government aft

The correct answer is A) Germany's proposal that upon an alliance with Mexico, it would ensure the return of Mexican land lost to the US.

Germany tried to convince Mexico to join them by using Mexico's resentment towards the US. After the Mexican-American War, Mexico gave up 2/3rds of its land in what is known as the Mexican Cession. The Mexican Cession resulted in the US getting a significant amount of land from Mexico. This includes territories such as California, Arizona, and Utah.

The land lost in the Mexican Cession was the land that Germany was referring to in the Zimmerman Telegram. Getting this land back would restore Mexico's territory back to its prewar size.
