Please draw (a) in details and then answer b

Cyclopentadiene can be deprotonated with relatively weak bases and shows much higher acidity than the vast majority of other simple hydrocarbons. a) Draw the resonance structures of the resulting anion, and develop a molecular orbital diagram. b) Utilize either of these (resonance structures or MO diagram) to identify a factor that could explain the strong stabilization of the cyclopentadienyl anion
