In what two ways does a tornado cause damage to property

It can make houses collapse
damage such as inside things can break ect
environmentally the tornado will cause a lot of damage
I think it can cause floods!!

The answer is b im not sure 

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.
