net ionic equation doesn't make sense

[Vsno123]

Here's a question from Achiever test 1:

What is the net ionic equation for the reaction between FeS and HCl?

I thought I knew how to do net ionic equations until I ran into this question. I already have the solubility rules memorized which is why I don't get why FeS would dissociate in the first place since it is insoluble.

The answer given is:
FeS(s) + 2H+ (aq) --> H2S(g) + Fe2+ (aq)

hmmm... i think it's because FeS is soluble in acid... i'm not sure how we're supposed to know this. hopefully since it's from an achiever test, it means it's one of those hard/random gen chem questions?

FeS(s) + 2HCl(aq) --> FeCl2(aq) + H2S(g) Equation

FeS(S) + (2H+) + (2Cl-) --> (Fe2+) + (2Cl-) + H2S(g) Ionic Equation

FeS(s) + 2H+(aq) --> Fe2+(aq) + H2S(g) Net ionic equation
