What do the formation of communist parties and spread of Soviet education together show?

Correct answer: Spread of ideas through both organisation and training

The direct answer is A: ideas spread through both organisation and training. A communist party is an organised group that gathers supporters, explains a programme and coordinates political work. Soviet education and training helped teach socialist theory, discipline and methods to people who could carry these ideas into different places. The reasoning is: parties provided a structure for action; schools or training centres developed knowledge and political skills; together, organisation and education helped ideas travel and become practical movements. Option A is correct because it includes both channels rather than reducing influence to one activity. Option B is wrong because the formation of communist parties and Soviet education did not show a complete return of Tsarism; they were linked to opposition to the old monarchy. Option C is wrong because these developments were not acceptance of colonialism; many such movements criticised imperial domination. Option D is wrong because they did not expand feudal taxation. Remember the pair: party gives organisation, education gives training.
