I think you mean how to answer the questions so that you get your reward properly?
If it is so, then...well there is no right or wrong answer. It's all your opinion based. BUT, many sur.veys ask the same question over-time to prevent fakers/false information. Like in question 1 it might ask you: "How old are you?" and you answer "17". Then on question 15 it asks you the same question but this time you put "15". Then they will either tell you "sorry, but we could not find the best sur.vey for you" or they will simply not credit you.
So you actually have to take time reading the questions if you want to get your reward.
