Unlike euripides and sophocles, ancient greece’s aristophanes focused on
a) tragic plays
b) comedic plays
c) socratic philosophy
d) aristotelian philosophy

The correct answer is B. Comedic plays

Aristophanes is considered the most brilliant author of comedies in Greek literature. From his work it is clear that he was a man of great artistic and literary culture and that he didn't tolerate ignorance and rudeness.  He was involved in the struggles and controversies of Athens in favor of the aristocratic party, using theater as a battlefield. Conservative in his tastes and in his political attitude, Aristophanes brings to the theater the social, political, artistic and religious questions of the Athens of his time, criticizing with harshness and satirical humor the novelties that he considers demagogic and inopportune.   He directed his satirical capacity against the renovators of thought, such as Socrates, and against theater innovators, such as Euripides.

He lived 60 years, around 446 BC  to 386 BC.

4) Jim Crow laws

Jim Crow laws were a series of restrictions that enforced racial segregation in the United States. They were enacted especially in the Southern States of America through almost a century, from 1877 to the beginning of the Civil Right Movement in the 1950s,

The statutes prohibited African American to attend and be in certain places where white people were, such as neighborhoods, restrooms, building entrances, elevators, cemeteries, amusement-park, cashier windows, churches, hospitals, jails, universities, etc.

In the speech, Dr. Martin Luther King Jr. is clearly talking about these laws, because though in theory the racial segregation was supposed to be "equal" for both races, in practice, the laws were never equal, black people never enjoyed the same benefits that white people enjoyed, and the laws put African American in a place of inferiority and made them uncomfortable.
