In which situation would all of the larger elephants in a herd most likely stand shoulder-to-shoulder around a young calf?

to protect the calf from predators
to play a game with the calf
to keep the calf shaded if it is sunny out
to keep the calf dry if it is raining

To protect the calf from predators

Explanation:

When out on the open plain, and a threat comes upon a herd of Elephants, they immediately take action. The young, the sick, the elderly - are all herded into the middle of a circle. The other bigger Elephants then stand shoulder to shoulder, facing outward toward the threat.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.
