Well, the problem is that these are all misleading questions, not really a poll that will reflect what people think about ebook piracy (and what constitutes it).
2-3 don't actually have anything to do with piracy except as a way of mispresenting demographics and the 4th is ultra-misleading in that - that's the way it is NOW. Strangers do dictate an author's wage, by voting with their pocketbooks on if they should or should not buy a book.
Although I think that the question is supposed to suggest a 'pay what you think this book is worth' method? Which, personally, is one that always strikes me as particularly bad.
I think the real questions center around:
1. If people believe format-shifting of ebooks is piracy or not.
2. What to do if there is no authorized electronic copy.
3. The 'is there a lost sale if I'd never have bought it to begin with' theory.
