When huck refers to “trees with spanish moss on them, hanging down from the limbs like long, gray beards,” he is using an example of what literary device?

Simile it's the right answer I am 100% right

the correct answer is the following.

one of the groups i belong to is the boy scouts. this is a problem-solving group because it has tasks that we need to solve in order to other people in different activities such as the rescue of lost pets, or elder people in need.

the other group i belong to is kids pro environment, and is an information-sharing group that tries to create conscience about the risks and problems that generate pollution in our cities. we share information to other students and parents on the importance of keep our communities clean and our skies clear.  

sorry, i just really need points. and to this question, maybe i know the answer. but i have no time now. d
