In Pakistan, rivers are used to irrigate farmland, but not in Bangladesh. Question 8 options:
True
False

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.

Ithink the answer is either a , c or d

Ibelieve it was because of the gas act in order to preserve fuel
