What sparked the 1857 uprising?
A Corruption in the British courts and police
B Attempts to convert the sepoys to Islam
C Commanding the sepoys to use cartridges lubricated
with beef and pork fat
D All of the above

Well, I think the best answer will be is C. Commanding the sepoys to use cartridges lubricated with beef and pork fat. Because, The immediate cause was the introduction of cartridges lubricated with the fat of cows and pigs, a practice offensive to Hindus and Muslims.

Good Luck!

the group i'm selecting: greeks.

a first group of greek immigrants came to the us in the 1850s. the second group came to america starting in the 1890s due to economic opportunities they didn't have back in their home caused by the hardships of ottoman rule. greek immigration was 90% male, many of them expected to work and return to greece after earning enough capital, but ultimately had to remain in the us after the greek genocide.
