Answer:
The Black Codes sometimes called Black Laws, where laws governing the conduct of African Americans. The best known of them was passed in 1865 and 1866 by Southern states, after the American Civil War, in order to restrict African Americans' freedom and to compel them to work for low wages. Although Black Codes existed before the Civil War and many Northern states had them, it was the Southern U.S. states that codified such laws in everyday practice. In 1832, James Kent wrote that "in most of the United States, there is a distinction in respect to political privileges, between free white persons and free colored persons of African blood; and in no part of the country do the latter, in point of fact, participate equally with the whites, in the exercise of civil and political rights."

People who need life-saving drugs cannot do without them and surely will be willing to pay very high prices for them because a monopolist, such as one selling life-saving drugs, still faces downward-sloping demand curves.
Drugs are chemical substances that, when consumed, cause changes in the physiology or psychology of living organisms. Pharmaceuticals are generally distinguished from foods or substances that provide nutritional supplements. Drugs are consumed by inhalation, injection, smoking, ingestion, absorption through skin patches, suppositories, or sublingual dissolution.
In pharmacology, a drug is a chemical substance, usually of known structure, that produces a biological effect when administered to a living organism. Pharmaceuticals, also known as drugs or medicines, are chemical substances used to treat, cure, prevent, diagnose, or promote health. Medicines have traditionally been obtained by extraction from medicinal plants, but more recently they have also been obtained by disorders of organic synthesis.

a. Let's set a=3, b=1
In other words 
is odd, i.e. has remainder 1 when divided by 2. 
b. Let
There are 2n terms in the last factor. All the terms of the form
are odd. So when we add up an even number of them, we get an even number, call it 2m.
We've shown 
is divisible by four. 
Merry Christmas!
