I GM a campaign for a newbie party. For now everything is fine: they roleplay well, they don't solve their problems with violence, etc.
In their scenario, they came from a relatively small city sealed off from the world for a long period of time — one day the seal just vanished and their adventure began. The city was attacked by enormous, highly organised ants, and the City Council sent various parties, including one made up of the player characters, to search for allies. I imagine being cut off from the world for so long, the player characters would be a bit interested in what the outside has to offer them.
They're curious and ask questions about local lore. For example, they met a tribe of evolved ape druids who used the tactic of fleeing and hiding to survive these ants (not ideal allies for fighting, but good for scouts), befriended them, asked them to be allies, and upon learning of their tactics they just carried on with the search. They hunted with them though, exchanged presents, participated in rituals, formed blood bonds and so on, which went really well. They asked about gods, way of life, and so on.
However, the problem is they aren't asking the right questions. They didn't ask about the ants, or about other tribes, and so are missing out on information about those things. I fear them repeating this and continuing to miss out on this information.
(I've spoken to one player: it seems they forgot they came from an isolated community, so next session I'll remind them of this, and explain the standard mind-set of a normal citizen of the City. I'll repeat this on the beginning of every session until they understand -- they are really forgetful and don't write anything down.)
How can I get my players to ask the right questions to find out this information, so they don't miss out altogether?
(Note this is separate to How to get players to be curious and ask questions?, given they're not having trouble asking questions altogether)
