Why does it matter if fossils are treated like rocks or minerals? Describe how defining fossils as rocks or minerals impact things like monetary value, access to specimens for research, and ownership rights. Which side do you think has the stronger case - bones or minerals? Why?

The answer to the first one is barometer.

The answer is c, i, iii, and iv. this is because farming and mining deal with harvesting raw materials, construction work falls under manufacturing, and piloting a plane is a service. ii is wrong because making bread is using  raw materials to produce goods, which would fall under the secondary sector, not primary.
