> 9) Before your tribe lived here, what did the previous inhabitants eat and how did they sustain themselves?

Seems focusing on colonizers. Most people don't live in places with a clear separation between the previous tribe and the current tribe.

> Name three wild species that were not found here 500 years ago. Name one exotic species that has appeared in the last 5 years.

Is it really that common for a new exotic species to get introduced every 5 years? Animals and plants are mostly adapted to the biomes they originated in and usually don't survive well if you take them elsewhere, not much survives in temperate forests/taigas that doesn't already live there.
