That is what I also observe about survey , all the questions you are asked must be in line throughout what you are giving them . Some questions are psychological questions just to understand if you are truthful or not. That means you have been participating in it.There are some questions they always ask to know if you are paying attention or not. If you fail any of them they will disqualify you. So you have to pay attention. I think one of the reasons for disqualifications when you are about to finish is the number of needed participants is complete.
