Good point T-Hawk. I don't think that we saw any of those. Certainly nobody in this game starts with Ag / Hunting (Persia and Zulu are the only ones) and I doubt anybody would start off with Masonry.
I did check the pre-req status of Pottery if you have Ag / Wheel, but Wheel is an "AND" pre-req so it does not get the 20%.
