What tiny country lies between austria and switzerland

I don't know of any country lying between Austria and Switzerland, but you may be thinking of Slovakia or Sloveniawhich is just East of Austria.

Liechtenstein county lies between Austria and Switzerland.

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.

The correct answer is:   [b]:   "distortion" .
