the event that best defines the great schism between the east and west christian churches in europe in 1054 was the
a)
mutual excommunication of the pope and the patriarch of constantinople.
b)
repudiation by the emperor of the use of saints in the eastern church.
c)
destruction of the library at constantinople.
d)
massacre of the latins.

The answer here is A as they both tried to excommunicate each other while in fact neither of them knew what was going to happen.

Hope this helps!

explanation:

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

although the crusades failed to capture jerusalem, they had several major impacts on western europe. they increased the authority of the king: sometimes nobles died in battle without leaving an heir in which case the king got their land. kings passed taxes to pay for the crusades.
