which of the following was a result of the selective service act?
african americans could no longer serve in the military
women were now allowed to serve in all combat positions

Explanation:

1. For the first question: The Open Door Policy focused on U.S. trade access in China, unrelated to U.S. entry into WWI. The Zimmermann Note, Lusitania sinking, and Russia's exit all pushed the U.S. to join the war.
2. For the second question: The Zimmermann Note was a secret German proposal offering to help Mexico regain lost U.S. territories (Texas, New Mexico, Arizona) in exchange for allying against the U.S.
3. For the third question (corrected, as the marked option is incorrect): The Selective Service Act of 1917 established a draft system that required men to register for military service, creating a large pool of troops for U.S. involvement in WWI. The marked option is wrong because women were not allowed in all combat positions in WWI, and African Americans could still serve (though segregated).

Answer:

1. The Open Door Policy with China
2. Germany would help Mexico regain territory in the United States.
3. A mandatory draft of men for military service (note: the marked option in the image is incorrect; this is the correct result of the Selective Service Act)
