What are five major inventions that improved agriculture output between 1750 and 1870?

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.

its c not d   tell me if that´s correct

it allows shippers to carry commercial goods, which allows them to save time and money.
