That's right. The students who attempt my type of question will have a big statement with several data (which is loaded in a CSV to the DB). And will have several input answers, too. So the student should get the same data each time he want to attempt the question, because as it is a big statement, maybe he can answer a part and save it and after a few hours or a day he can answer the other part. That is why the variant needs to be fixed. I don't know if i have explained myself.
