So i have this school assignment and i can t figure it out how to insernt a new column ?

You will create a process in RapidMiner that will read the fake.csv and true.csv files, it will only keep the Text column from each one and after adding to both 2 a new column named Class and "fake" value for the first ones. " real "for the latter, it will unite them into a common data set @lionelderkrikor
