Worked Solution

Step 1: Shadow size depends on the distance between the source, object, and screen. Step 2: To make the shadow bigger, the object must block more light rays. Step 3: Moving the object closer to the source (torch) spreads the shadow over a larger area of the screen.

Correct answer: Move the toy car closer to the torch.
