Alyssa observed a flock of small birds in her yard. the birds visited a pair of feeders that her parents put out for them and splashed in the birdbath. which question is a nonscientific question that she might ask about the birds

A non scientific question would be anything that's highly subjective and cannot be tested like "What do they taste like" or "Which one is the prettiest?" Someone could say that they taste great and some could say that they taste bad, you can't check that objectivelly just like asking about their looks which are subjective as well.
