Q2:If you were a member of water supply OR flood emergency department and you had foreseen a situation where a river near your city would cause flooding in the monsoon season. What would be your plan of action to save the city from flooding?

Just do the math, then think

Maybe on the physical part? i dunno i just guessed plus i really need the points

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.
