Answer 1

Correct answers:
- A researcher studying bird migration patterns tags birds at a local bird feeder.
- A programmer wants to test a new app and asks their family and friends to try it out and provide feedback.

Why: Both pick participants because they are easy to access (convenience sampling). The neighborhood selection is cluster sampling and surveying every 10th customer is systematic sampling.
