Answer:
C) the monopoly model
Explanation:
First of all, collusion is illegal, and it is defined as secret cooperation between individuals or organizations that should be competing against each other.
In this case, the oligopolistic firms should be competing against each other trying to earn a larger market share, but since they collude together, they will act as if they were one single large monopoly. Usually collusion leads to higher prices, benefiting the companies but hurting the customers. Since all the competing firms in the market decided to work together, they will set their prices in a similar manner to a monopoly since there is no real competition between them.
I think the answer is a. I'm not 100 sure though.
Answer:
person's driver's license number
Explanation:
A single valued attribute means that a person or a thing can only have a single value for that attribute, for example, you can have only one social security number since having more than one is illegal.
Following the same logic, you could only have one driver's license number, since you can only have one license.
But you can have more than one cellphone, you can also have more than one car, and finally you may have attended more than one college.
