A) We can still consider Leonardo da Vinci a man of outstanding ability.
b) He could use both his hands with great ease. For drawing and writing he used his left hand, for painting he used his right hand.
c) He can write backwards from right to left.
d) He tried hard to understand the "why" of everything but he couldn't.
