It's important to identify potential sources of bias when planning a sample survey.
When we say there's potential bias, we should also be able to argue if the results will probably be an overestimate or an underestimate.
Try to identify the source of bias in each scenario, and speculate on the direction of the bias (overestimate or underestimate).
