This 4-year-old boy has been noted by his parents to have a droopy right lid since birth.  In addition, they noted as an infant his right upper lid "bounced" up and down when he fed from a bottle and the lid continues to act in this manner when he chews.  The boy is healthy and has no known blood relatives with any sort of ptosis.

1.	The most likely diagnosis is:
	a.  congenital ptosis, right upper lid b.  Marcus-Gunn jaw winking c.  Horner's syndrome d.  misdirection of the third nerve
2.	The cause of this condition is:
	a.   misdirection of the VII cranial nerve b.     misdirection of the levator aponeurosis c.     clinically unknown d.  misdirection of the V nerve to supply the levator muscle
3.	Treatment of this condition depends on all but one of the following:
	a.  the patient's symptoms b.  function of the levator c.  strength of the internal pterygoid muscle d.  amount of ptosis
