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.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
