Question

How are they alike?
---------------------------------------
Elephant's side and a wall.

Elephants knee and a tree.

Elephant's ear and a fan.

Elephants tail and a rope.
---------------------------------------
Need help figuring out how they are alike.

I got "big and sturdy" for #1
and "long and whippy" for #4

please help thank you.

Imagine a blind person feeling an elephant. The knee might feel like the knot on a tree.

What do you think s/he might think of when feeling a fan and an elephant's ear?
