What was the achievement for the great strike

here :))

Explanation:

What did the great railroad strike of 1877 achieve?

It spread across the nation halting rail traffic and closing factories in reaction to widespread worker discontent over wage cuts and conditions during a national depression. Broken by Federal troops in early August, the strike energized the labor movement and was precursor to labor unrest in the 1880s and 1890s.

b. major john c. frémont led a rebellion called the bear flag revolt.

explanation:

during the bear flag revolt, from june to july 1846, a small group of american settlers in california rebelled against the mexican government and proclaimed california an independent republic. the republic was short-lived because soon after the bear flag was raised, the u.s. military began occupying california, which went on to join the union in 1850. the bear flag became the official state flag in 1911.
