Final answer:
The Pullman Strike, a significant labor conflict in 1894, and the Homestead Strike of 1892 were the two major strikes that happened prior to Easter 1894, with the Pullman Strike being the direct answer to the student's question. Option C is correct.
Step-by-step explanation:
Among the strikes happening prior to Easter 1894, other than Coxey's Army, was the Pullman Strike. This was a significant labor conflict in the summer of 1894 when workers at the Pullman company in Illinois protested wage cuts and high rents.
The Homedstead Strike also predated the Pullman Strike, occurring in 1892 at Andrew Carnegie's steel plant in Pennsylvania where workers protested against pay reductions. While both the Great Railroad Strike of 1877 and the Haymarket Riot of 1886 were pivotal labor conflicts as well, they did not directly precede the Easter of 1894 like the Pullman and Homestead Strikes did.
Thus, the correct answer to the student's question, which strike was happening prior to Easter 1894 other than Coxey's Army, would be C) Pullman Strike.
