Four questions that need answers?

These questions are for homework that I do NOT . The worksheet is about reading terms and it's a crossword puzzle. I've answers the rest of them (35 questions to be exact) and I have three left that I do NOT get. I'll ask you the questions that you can hopefully answers. (1) Conclusion based on evidence that is not explicitly stated. (It's nine letters long.) (2) Origin of a word traced back in time (nine letters long.) (3) Present events that occurred earlier than the current time (nine letters long.) I hope someone will answer these questions, thank you!
