People argue whether "suffering" is the best translation. Perhaps it depends on context. I guess dukkha has range of meaning from (extreme) anguish to (chronic) unsatisfactoriness to (eventual) insufficiency.
And whose goal?
And is it possible that the goal varies -- at the beginning people are caught up in suffering and want to escape it. Perhaps later they're not suffering so much, and there's a slightly different goal i.e. "liberation" or "unbinding".
The "root" poison is ignorance.
They're called "clinging-aggregates". To the extent that the doctrine distinguishes "craving" from "clinging", I think it's "clinging" to aggregates.
I think that tool is the noble eightfold path -- "right view" etc.
Seeing the three characteristics is an example of right view, Jhana is an example of adhicitta-sikkhΔ
Here I think I'd refer to the Dhammanusati and say, "The doctrine is effective etc.".
