Which careers require completion of secondary education, but little to no postsecondary education? a) mathematical technicians and mechanical engineers b) sociologists and electronics engineering technicians c) food science technicians and zoologists d) nondestructive testing specialists and surveying technicians

The correct option is C. 
Food science technicians are those who help food scientists and technologists in the area of food production and quality control. The level of education required by a food technician depends on the employer. The standard qualification is an associate degree but some employers will absorb high school graduates, who have relevant experience and skills. The field of zoology is very wide and many work in the sector in varying capacities. For those who take physical care of the animals and give them food, a college education is not required for the position of zoologist.
