Problem: Race (human categorization):

Groups of humans have always identified themselves as distinct from neighboring groups, but such differences have not always been understood to be natural, immutable and global. These features are the distinguishing features of how the concept of race is used today. In this way the idea of race as we understand it today came about during the historical process of exploration and conquest which brought Europeans into contact with groups from different continents, and of the ideology of classification and typology found in the natural sciences.

Where did Europeans come into contact with other groups?

A: different continents

Problem: Beginning with the advent of beat match DJing, in which Bronx DJs (Disc Jockeys) including Grandmaster Flash, Afrika Bambaataa and DJ Kool Herc extended the breaks of funk records, a major new musical genre emerged that sought to isolate the percussion breaks of hit funk, disco and soul songs. As hip hop's popularity grew, performers began speaking ("rapping") in sync with the beats, and became known as MCs or emcees. The Herculoids, made up of Herc, Coke La Rock, and DJ Clark Kent, were the earliest to gain major fame. The Bronx is referred to in hip-hop slang as "The Boogie Down Bronx", or just "The Boogie Down". This was hip-hop pioneer KRS-One's inspiration for his thought provoking group BDP, or Boogie Down Productions, which included DJ Scott La Rock. Newer hip hop artists from the Bronx include Big Pun, Lord Toriq and Peter Gunz, Camp Lo, Swizz Beatz, Drag-On, Fat Joe, Terror Squad and Corey Gunz.
What types of music did hip hop emerge from?

Context and question: The first major model for communication was introduced by Claude Shannon and Warren Weaver for Bell Laboratories in 1949 The original model was designed to mirror the functioning of radio and telephone technologies. Their initial model consisted of three primary parts: sender, channel, and receiver.

Shannon and Weaver also recognized that often there is static that interferes with one listening to a telephone conversation, which they deemed noise.
What was the sender in the initial model?
Answer: the part of a telephone a person spoke into

Question: "Old Style" (OS) and "New Style" (NS) are sometimes added to dates to identify which system is used in the British Empire and other countries that did not immediately change. Because the Calendar Act of 1750 altered the start of the year, and also aligned the British calendar with the Gregorian calendar, there is some confusion as to what these terms mean. They can indicate that the start of the Julian year has been adjusted to start on 1 January (NS) even though contemporary documents use a different start of year (OS); or to indicate that a date conforms to the Julian calendar (OS), formerly in use in many countries, rather than the Gregorian calendar (NS).
Is there an answer to this question: What law did the British make to cause the use of the Gregorian calendar?

Answer: Calendar Act of 1750

It was demobilized at the end of World War I, and was replaced by the Regular Army, the Organized Reserve Corps, and the State Militias.
