7. A rule for hiring a set number of people from a minority group is_

C. A quota .

Explanation:

Minority groups of people are, as is obvious from the very term itself, those that belong to the minority section of the society. Their practices, be it religious, traditions, customs, and race/ ethnicity are lesser in number as compared to the major sections of the whole population of the place.

As such, this group of people is given rights or 'privileges' in the society or workforce where they are given 'reservations'. This reservation policy or quota allows or rather prioritizes them for the job, and gives them a chance to be hired or given the job.  

the correct answer is “opportunity cost”. opportunity cost is what a company misses out because it decided in one option over another one. in this case, the company decided to invest in building a factory so it gave up another possible benefit or profit in order to achieve success with the factory.  

trade-off is not the correct answer since it is a situation in which you accept losing something in return for benefits in other areas.

and finally, consequence is a general term used to accept what it comes when you make a decision. it can be a positive or negative consequence depending if the decision you took was the correct one.  

what are the choices btw if it was me id say the lack of money to continue with education
