A young boy was walking with his father along a country road. When they came across a large tree branch   1  the pathway, the boy asked, “Do you think I could   2  it?”

His father answered, “If you use all your strength, I am sure you can.”

The boy tried   3  to lift, pull and push the branch, but it wouldn’t budge. 4 , he said, “Dad, you were wrong. I can’t do it alone.”

“Try again,” his dad said.
