I would say D.
because you can’t count on foraging to feed 100 people, whereas agricultural growing of food is more effective when you have more people. you can plant 100 seeds, but you can’t guarantee to find 100 berries while foraging. hope this helps!
That religion may not be the end all be all of every scientific question ever posed. What I mean is that religion may not be able to answer every question that comes from the world around us, an example being how religions interpreted the Earth as being the center of everything, when scientifically this is not the case and religions disputed this until they eventually died out or re-evaluated their beliefs.

Poland has been Catholic for a long while and since the Church is an ecclesiestical institution, it plays no big role in trade. The Soviet Union had a very protective attitude towards its products and only a few categories of them were exported; it is quite possible that exports dropped during this period. THe Warsaw Pact marked a significant counterpoint to the NATO initiative but most countries were already good trade partners to the Soviet Union (and again, the pact was not about trade). The right answer is European Union; the open borders and the influx of technology has increased the potential for exports from Poland.
