There is a collection of tests on history. Question and answer. How to classify questions by topic?

Answer 1

Well, how. Take a question, read, think (!!!), then write what topic this question relates to. Then move on to the next question.
What they asked - exactly the answer to it and received. They meant something else - give yourself the trouble to clearly formulate the question. Moreover, it is desirable that others besides you understand it.
PS About that collection, whether you have "tests", "tests" or "texts" - I'm just not talking about it. You need to re-read your question and double-check it. And why, right?
