What did the Russian Revolution inspire political activists in other countries to do?

Correct answer: Form organisations and try for change

Direct answer: Option A, activists were inspired to form organisations and try for change. The global influence of a revolution is seen when people in other countries study its ideas and create movements based on them. The reasoning is: the Russian Revolution showed that an old political order could be overthrown; socialist ideas appeared capable of guiding a government; activists elsewhere therefore organised parties, groups and campaigns to seek social and political change. Option A is correct. Option B is wrong because the revolution challenged monarchy rather than encouraging activists to strengthen it. Option C is wrong because expanding colonialism contradicts the equality and anti-exploitation message associated with socialist movements. Option D is wrong because protecting feudal taxes would defend an old system of privilege, not promote revolutionary change. Remember: global influence means ideas travel and people organise, not that every country copies the same event exactly.
