Question

Select the correct answer from the drop-down menu.You are conducting a survey on the best beaches in the world. The group that would probably give you the most reliable data is_________

Answer 1

In order to collect information about the best beaches, it's more reliable to survey people that already visited the beaches, so they can give you information about what they experienced.

It's not good to survey officials who manage the beaches, because they will be biased to say to you that their beaches are the best ones.

Therefore the correct option is the third one.
