Please help, I am trying to help (or at least I was last night) with this apostrophe task. I thought I understood. It seems I do not.
In the forest, the wolves' howls’ echoed as the trees' branches’ swayed in the wind. Underground, in the foxes' home, they huddled together to get warm. In the trees’, the squirrel’s feet pattered as they scrambled up and down the branches’ looking for food.
Is that correct? Why does branches have an apostrophe? Howls'?
