Please answer the following question: I am testing my students' logic. What is the answer they should choose between "picket fence" and "tree branch"? Logic test: A squirrel runs along a long tree branch. It ends at the top of a picket fence. The squirrel uses the same amount of energy but runs slower across the picket fence. Does this happen because (A) the tree has more ridges or (B) the picket fence has more ridges?
A:
tree branch
