1 Read the paragraph from the section "Upset By Many Things."
Many things can be stressful to an elephant. They can be spooked by a dog walking by, a snake rustling the grass or the roar of a male elephant. Sometimes the scientists weren't even sure what stressed them out. Regardless, they know what a stressed-out elephant looks like. The animals stick their tails out straight and flare their ears. They make loud sounds such as trumpeting, rumbling or roaring. They even poop and pee!
