Question

in the spanish civil war, the republicans represented the
fascists brought to power by the military.
democratically elected government.
conservatives revolting against fascists.
communist party revolutionaries.

Explanation:

The Republicans in the Spanish Civil War were the democratically elected government. The war was between the Republican government (which had a coalition of various left - leaning and democratic forces) and the Nationalists (led by Franco, with fascist and conservative support). The Republicans were not fascists (so the first option is wrong). The conservatives were mostly on the Nationalist side (so the third option is wrong). While there were communist elements in the Republican coalition, the Republicans as a whole were the democratically elected government, not just communist revolutionaries (so the fourth option is wrong).

Answer:

democratically elected government.
