In 1915, the united states’ neutral stance was tested when germany a. asked mexico to attack the united states. b. sank the passenger ship lusitania. c. broke a deal to limit submarine warfare. d. signed the treaty of brest-litovsk with russia.

The correct answer is B.

During WWI, in 1915, the British passenger ship named Lusitania was sunk by the Germans and 1,198 civilians died. This event positioned the general opinion against Germany and contributed to the decission of the US to participate in the war.

Option A is also a factor that contributed to US participation, but such petition was formulated by Germany through the Zimmerman Telegram in 1917 and not 1915. Hence, it cannot be the correct option.

Options C and D did not influence US involvment.

the main inference that can be drawn from jean jacques rousseau's book the social contract is: a. people can enjoy civil and physical freedom, even if it sometimes harms society.

could you give me the options ?
