Salut,
1. Marie Curie didn't discover uranium. She discovered radium.
2. Hannibal didn't take camels over the Alps. He took elephants.
3. Alexander the Great didn't ride an elephant called Bucephalus. He rode a horse.
4. Edmund Hillary and Tenzing Norgay didn't climb the Andes in 1953. They climbed Mount Everest.
Mult succes! :)
