Francis is organizing an event in Calgary in western Canada. She wants to have a multi-cultural night and invite recent immigrants to participate and
share their cultures. Based on typical immigration patterns, most of the
participants are likely to be from:
A. Africa
B. South America.
C. Asia
D. Europe.

Jobs that people can do to earn a living in southwest asia are being a diving instructor, a journalist, a teacher, a photographer, a dj, a tour guide, a web designer, a fitness instructor, and more.

Why you put last one a? i think is b.

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.
