What is the main idea of the passage?

A screen coordinates tiny red, green, and blue pixels at different brightness levels to form complete images. (The passage moves from one pixel’s colored light to the grid and software that produce an image.)

Why do the colored dots look like one picture from farther away?

The eye combines closely spaced pixels into larger shapes and details. (Normal viewing distance makes the tiny coordinated parts merge perceptually into edges and forms.)

What does “pixel” mean?

one tiny controllable picture element on a screen (The opening defines pixels as the tiny parts from which a screen picture is built.)

Which three light colors does the passage name?

red, green, and blue (The first paragraph lists red, green, and blue light in each pixel.)

The Picture Made of Tiny Dots: Level 1 Reading Comprehension Questions

A screen picture is built from tiny parts called pixels. Each pixel can shine with a mix of red, green, and blue light. From nearby, the parts may look like colored dots.

Different brightness levels create many colors. Red and green light together can appear yellow. All three shining strongly can appear white. Dark pixels give off little light.

A screen places rows of pixels close together. From a normal viewing distance, the eye joins them into edges, letters, faces, and shadows. More pixels can show finer detail when the screen size and image support them.

A pixel does not know what it depicts. It follows a number telling each color how brightly to shine. Software changes many numbers rapidly to make video move. The complete picture emerges from a grid of small, coordinated lights.
