Answer to Question 1

D
To date, there is no definitive proof that any drug can protect dopaminergic neurons from pro-gressive degeneration. Levodopa has shown neuroprotective effects, but studies have demon-strated toxic effects in the doses required for this purpose. MAO-B inhibitors have shown bene-fits, but only in animal studies. Vitamin E was once theorized to offer this protection, but recent studies have provided good evidence that this is not the case.

Answer to Question 2

C
Mifepristone is most effective if it is used within 7 weeks of conception. The timing specified in the other responses is incorrect.
