Jazz music is considered America’s original art form it began in the late 1700s and
early 1800s among African Americans living in ihe southern states of Mississippi, Georgia,
and Louisiana Interestingly, its popularity over the ensuing centuries included people of different ethnic backgrounds and stations in life from places all over the United States and other countries Jazz is characterized by its unique sound and improvised musical styling, _ which work together to evoke intense emotion While it has continued to evolve since its
big-band-era jazz to more modern jazz ,
in popularity in the 1930s Swing bands featured a soloist, which is where improvisation played a key part While the band followed a certain melody, the soloist played notes that’
stood out and displayed his or her unique musical talent Swing was very popular because it was lively and people could easily dance to it Dance halls saw a boom in attendance during this period During the economic depression of the 1930s, many found
solace and a positive outlook in the bright sound of jazz The radio also helped to spread
the fame of swing music with nightly coast-to-coast broadcasts of bands and artists such
as Duke Ellington, Benny Goodman, Louis Armstrong, and Ella Fitzgerald
While the thirties are known mainly for swing, a smaller movement termed Kansas City
Jazz rose in popularity for a time Kansas City Jazz was similar to swing in that it featured
improvisational solos and similar instruments Kansas City Jazz was often played in smaller
venues located around Kansas City, Missouri, which was a stopover for traveling bands
during the Depression Era Its leaders encouraged the development of night clubs where improvisational musicians could exhibit their talent It served as a type of bridge between the swing music of the late twenties and thirties and the newer sound that emerged in the
1940s As the Kansas City Jazz movement grew, most of its performers migrated to New York and other big cities where they could have more exposure ;
in the forties, jazz experienced a transition away from the mainstream, dance-style
music played by big bands toward a more challenging type of sound for musicians The
new sound was called bebop It was played by small groups of musicians who focused
on harmony, tempo, and the art behind making the music The popularity of the bebop

05 Biology
lsland Biogeography Model
Since the 1960s, scientists have been studying the composition and stability of island communities Specifically, they have been interested in what it takes to maintain life in these isolated areas As a result, they developed the island biogeography model, a model that not only provides information on island populations, but also provides insights into conservation
island will maintain equilibrium, or a state of balance, amid the fluid: changes of immigration and extinction In other words, the number of species on an island remains constant In
an experiment in the US state of Florida, islands of mangrove trees were found to house many different species of arthropods Scientists documented the numbers and types of
species They then sprayed insect poison over the islands, destroying all of the arthropods there They observed the islands over the next year, as species of arthropods from the
area surrounding the mangrove islands moved onto the island and repopulated it Within
a year, the number of species of arthropods was almost identical to what it had been before spraying the poison However, the scientists soon discovered that the individual species were not identical to the ones that had been there before So, while the number
of species was the same, the diversity of species was quite different This study proves that although the species number remains constant, the types of species do not
The island biogeography model can also apply in places that are not technically
islands In fact, the islands used in this research were man-made, isolated areas that had been created to meet an ever-increasing demand for land and natural resources These
islands form when humans clear out vast amounts of vegetation for arable land and living
space Their actions cut off small areas of land and forest from larger communities, such
as when loggers separate a small parcel of forest area from the larger forest Hence, these
isolated pockets become “islands,” or areas separated from their larger communities
By reducing areas of land into islands, humans have a significant impact on wildlife The island biogeography model states that the larger the island, the higher the rate of extinction
A) This is due in part to a larger number of species coming to the island to colonize it
As new species immigrate, there begins a competition for resources on the island B@ B)
Since there is a fixed.amount of resources on any given island, some species will not survive
in the struggle § ©) On a smaller island, the rate of extinction would be lower, and so
would the corresponding immigration of new species § D) The more isolated these small
