What is one theory about the reality of dragons?

One of the early dinosaur fossils that were discovered was the pterodactyl and it was believed to be what a mad man said he had seen .he called it a dragon but he was disproven when he said  it had a different structure

Or so it is believed

d is the best answer for this question.

i think the correct answer would be adjustments in life roles.  this causes for one to adjust or change totally his/her career or lifestyle since the present is not beneficial to the life role he is at. for instance, you became a mother you would of course stop going to malls and enjoying life outside. you would be staying at home taking care of your child.
