Your homework can't be just, 'tell me which of these two immensely important historical concepts is more historically significant' as that is utterly subjective. Which of the two interests you? They will both have an impossible number of citations to choose from, as again these are two hugely important things, they were both significant at the time, and both remain significant, though obviously Maoism possesses more obvious modern ramifications.

I think your definition of significance needs reworking also, you're basically asking 'how important were these things? How can I measure their importance.' well for things as historically as significant you can't really just tally up influence, those three things are all immensely influential.

Finally, the answer to the specific questions you pose are ones you should answer yourself tbh, that's the assignment right? Like, all of the information for those three concepts is out there, pick which interests you the most and do some research...
