It was the position of the soviet union that there could not be a workers revolution in Spain 1936 but rather society needed to establish bourgeois democracy.

The Spanish Revolution was a workers' social revolution that began during the outbreak of the Spanish Civil War in 1936 and resulted in the widespread implementation of anarchist and more broadly libertarian socialist organizational principles throughout various portions of the country for two to three years, primarily Catalonia, Aragon, Andalusia, and parts of the Valencian Community. Much of the economy of Spain was put under worker control; in anarchist strongholds like Catalonia, the figure was as high as 75%. Factories were run through worker committees, and agrarian areas became collectivized and run as libertarian socialist communes. Many small businesses like hotels, barbershops, and restaurants were also collectivized and managed by their workers.

The collectivization effort was primarily orchestrated by the rank-and-file members of the Confederación Nacional del Trabajo (CNT; National Confederation of Labor) and the Federación Anarquista Ibérica (FAI; Iberian Anarchist Federation). The socialist Unión General de Trabajadores (UGT; General Union of Workers) also participated in the implementation of collectivization.

given the fact that the question is about the detail that best support the idea that oppressive leaders use   propaganda to achieve thir goals,   the first option does not refer to any kind of propaganda, since it only tells about that the milk and the windfall apple should be reserved for the pigs. in the second option, that is, "snowball and napoleon sent out flights of pigeons whose instructions were to mingle with the animals on the neighbouring farms, tell them the story of the rebellion, and teach them the tune of "beasts of england". it can be identified that the oppressors make use of the propaganda, which is represented by the pigeons, and the information they have to tell other animals about what was happening in the farm in order to get their objectives. for that reason, the right answer is the second option, taking into account that the third option do not refer to propaganda since it only talks about that they did not want jones back. and, finally, the last option refers to the result of the given news, but it does not mean about the propaganda they used to achieve their goals.
