Answer:
1. Without a calendar we could not know when to celebrate any of the festivals on particular days. We would even get the days of the week confused after a while. We would not be able to tell when a year had gone by, so it would be hard to keep track of someone's age.
2. Without numbers we wouldn't be able to count or measure anything. We would forget our age one day, and possibly forget how to count. Also we wouldn't be able to tell time, unless we used the sun. It would make life very problematic.
3. It would take very long to get us somewhere. We could no longer travel with airplanes, since they use wheels to take off. Such a simple thing as going to the grocery store, would turn into a huge task. Traveling would take very long to do, or might be non-existent if we didn't use horses.

Hey there,
One situation that can be caused by both human and nature would be A: Forest fires.
All forest fires need to start is a very small fire. As most trees are very flammable and can catch fire easy. This can be by humans such as a match or a cigarette. Or by nature maybe a lightning strike to start a small fire that would turn into a large one.
B: Would be incorrect because fossil fuels is done by humans. We use it as gas and fuel for various things. And cannot be done randomly by nature.
C: Would be incorrect because humans often resort to large deforestation to get lumber for wood. Usually for houses or other building objectives.
