In the quiet town of Verkhniye Gorki, a legendary artifact existed among the fifth graders of School No. 4: the "Golden Notebook." It wasn’t actually gold, of course—it was a standard —but every single answer was correct, written in a neat, mysterious hand [1, 2].

The source of this magic? A secret digital oracle known as . The Quest for the Lab Report

Our hero, Kostya, was in a bind. His workbook was a graveyard of blank pages. Tomorrow, the formidable Maria Ivanovna would check the lab report on "Soil Composition." If Kostya didn't have the answers, he’d be grounded until the next solar eclipse.

The class held its breath. Usually, Kostya would shrug. But the "Golden Notebook" had taught him well."Because of its size and orbit, Maria Ivanovna. It's a dwarf planet," he said confidently, remembering the clear explanation from the site [1, 3].
