Do 90man SNG's count as MTT's for FTPA challenges?

Same question as in the title:
Do 90man SNG's count as MTT's for FTPA challenges?

Generally not for a MTT challenge , Depends on the challenge

For the speculative hand challenge:
With 2 or more limpers already in the pot in a real money NL Hold’em MTT or ring game, call the big blind with a speculative hand. Repeat 3 times.

I have not done that challenge yet but I am still leaning towards a pure MTT rather than large SnG Mtt(basing this on other challenges I've done)

What's this challenge? Never heard of it!

Anyway, I don't see why they can't be classed as MTT's considering they actually are MTT's!!! Only difference is they "go" when everyone's joined..
