Listen to the passage. Use the test notes to answer.

Testing Castle Windows

The beach center holds a sandcastle show. Imani tests materials for model castle windows. An adult aims a flashlight into a dark test box, away from eyes. A tilted holder sits in the beam. One white card is behind it. Another is above it. They change the material. The flashlight, holder, and cards stay put. They check both cards for light spots.

Clear plastic: bright spot behind; no spot above.

Wax paper: dim spot behind; no spot above.

Thick felt: no spot on either card.

Plastic safety mirror: no spot behind; bright spot above.

What did Imani change to compare the window materials?
