Title: वैकल्पिक

Text: Dolphins sleep, but they do it in a very different way than humans do. These creatures sleep with only half of their brain at a time, while the other half stays awake. This allows them to keep one eye open, which can watch for predators while half of their brain rests. Dolphins switch which half of their brain is asleep every few hours. प्रत्येक पराग्राफले परीक्षण हुनेछ।
