Which statement is the most reasonable testable prediction for the hypothesis: all birds can fly?

-observe all the birds outside your home for a week to see if they all can fly
-examine the list of all known species of birds and determine if any species cannot fly -take a random sampling of five birds from around the world to verify that they can all fly

"Examine the list of all known species of birds and determine if any species cannot fly" would be the most reasonable answer.
