Answer:
Alexander Graham Bell, an American scientist invented the telephone. It has proved to be an extremely useful invention. It is not considered a luxury today. In fact, it is now a necessity. Even in small cities, towns and villages, more and more people now have telephones.
Each telephone has its own unique number. No two telephones in one city or town can have the same number. To talk to someone, we have to first dial his or her telephone number. Telephones are not only meant for social communication rather they are essential to encourage business. One can place and take orders, enquire, exchange information, book tickets, request for payments, track or report status of delivery, take or cancel appointments, etc.
Telephones are extremely convenient to exchange information. They save time, energy and labour of personally going and have any information. They are a big boon in times of emergency. It is said that in times of need, a telephone can literally save a life. Mobiles or landlines are meant to help us. We should not overuse them to count their disadvantages.

The correct answer would be, Limitation Model.
A compromise approach that would make drugs legally available, but only through certain institutions and professions is known as Limitation Model.
Explanation:
When something is legalized at some places and those places are given legal authority to sell or purchase things, then this is the limitation model, in which there are limits to the legalized products to be sold on certain places only.
So when drugs would be made legally available but only through certain institutions and professions, this is know as the Limitation Model.
The places to sell the drugs are being limited and only few places or professions and institutions are legalized to sell the drugs. This is the Limitation Model.

If the random variable y denotes an individual’s income, Pareto’s law claims that<u> P(Y>=y)= (k/y) raised to the power of 9</u>. Here k refers to the minimum income of the entire population.
Pareto's law states that for different outcomes, almost eighty percent of the results come from the twenty percent of the causes of the event. We also call it the 80/20 rule or the rule of the vital few or even the principle of factor sparsity.
Joseph M. Juran, a management consultant developed this concept keeping in mind the context of quality control as well as improvement after he read the works of the Italian economist Vilfredo Pareto.
