Which region is located between 23.5 degrees north and south of the equator?

That would have to be the large continent of Africa! Hope this helps :)

South wales composes a lot of coal in that region.

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.
