¿Qué factores económicos, sociales y políticos ayudaron a que Mussolini en
Italia, Hittler en Alemania, y Stalin en Rusia pudieran llegar al poder?

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.

Lol why dont you actually do the work instead of have people do it for you. jk i do it too lol
