What legislation did Grangers pass in 1874 related to freight shipments?

The legislation that Grangers passed in 1874 related to freight shipments is known as the Granger Laws. These laws were aimed at regulating the railroad industry, particularly in terms of freight rates and practices that were seen as unfair to farmers. Grangers, who were members of the Patrons of Husbandry, organized to advocate for the interests of farmers, especially in response to the monopolistic practices of railroads and grain elevator operators.

The Granger Laws sought to establish more favorable rates for farming goods, reduced discrimination against small shippers, and increased overall transparency in freight charges. This movement was significant in prompting state governments to take action against exploitative practices and paved the way for subsequent regulatory measures in transportation and agriculture.

In contrast, the other options do not accurately reflect the laws or initiatives associated with the Granger movement during this period.
