I want to know the answer to the following question:
Def Leppard's album Hysteria churned out how many hit singles?
All the background I'm provided with is that "Mötley Crüe with Girls, Girls, Girls (1987) continued their commercial success and Def Leppard with Hysteria (1987) hit their commercial peak, the latter producing seven hit singles (a record for a hard rock act).". Is that enough to answer the question?
