Worked Solution

Step 1: Setup A forms a dark shadow, meaning Sheet A blocks most/all light (opaque). Step 2: Setup B forms a faint shadow, meaning Sheet B allows some light to pass through (translucent). Step 3: Therefore, Sheet B allows more light through than Sheet A.

Correct answer: Sheet B allows more light to pass through than Sheet A.
