This is a personal question, which means that only you can answer it. However, I can give some examples that might help guide your work.
An example of a primary source that you might encounter in your own life is that of a news article. As this article is likely to be written by a reporter witnessing the events, it can be considered a primary source. On the other hand, an example of a secondary source would be a non-fiction book that talks about a historical event. This is because such a book would give a second-hand account of an event based on historical information.
During this era, human technology boomed. In this era, nomads have started farming. Nomads have stopped moving from one place to another. They have started forging metal tools. They also started pastoralism. They have communities and tribe. They were able to create a system on their own.
Do you know the context?
I suppose the quotation is stressing that the writer has put a lot of effort into getting their argument/grievances heard by the parliament, and that said parliament is 'tyrannical', implying that it rules without concern for the people or accountability to them. It seems that the quote may be a way of justifying some later action, essentially saying; 'we've tried and failed to do this in the proper way, so now we must be more forceful'.
