A man makes breakfast. He puts some toast in the toaster, and mixes some eggs with a little milk in a bowl. As he begins cooking the eggs, he smells the toast burning. He takes the toast out of the toaster and puts some butter on it, which melts. Finally, he pours some orange juice through a strainer to remove the pulp. He eats the meal, and he digests it as he drives to work in his car.

The correct option that identifies a chemical and a physical change in the scenario is:

Burning toast is a chemical change; straining orange juice is a physical change.

Burning toast involves a chemical change because it alters the chemical structure of the bread, producing substances like carbon. Straining orange juice is a physical change because it separates the pulp from the juice without changing the composition of the juice itself.
