Juneteenth is a holiday, or commemoration meant to celebrate word of emancipation finally coming to a group of enslaved people in Galveston, Texas. It commemorates this group of slaves who learned that they had been emancipated months earlier. The holiday is meant to commemorate the emancipation of 4 million slaves, but particularly the small handful who weren't aware that emancipation had come months earlier.
I'm glad you asked!
Juneteenth is the day that Abe Lincoln declared that all slaves have to go free.So it should be important for black people and a memory about how some white people sacrifice for us.
there are two statements that are incorrect.
1. the marshall plan was a lend lease program. it was an economic plan that europe redevelop itself after wwii.
2. einstein didn't really do anything to further the allied cause in building the bomb. he merely sent a letter to fdr telling him (in 1939) that if the united states entered the war, perhaps it would be wise to build the bomb before germany did. i would say this answer is incorrect, but when america entered the war 2 years later, fdr thought it might be a good idea to take einstein's advice.
the 4th choice is definitely so wrong that is likely the single answer of this question
