Answer:
Review the model paragraph. How many of the same revisions did you make?Many arts, including literature, painting, fiction, poetry, and theater, made the Harlem Renaissance special, but music holds a special place in the history of the period. Featuring a new style of piano playing, the people who went to hear this new jazz sound thought it was a refreshing take on an old sound. Jazz began to attract white music fans to traditionally African American clubs, where African Americans visited exclusively. Whites found much in common with their fellow music fans. If the featured pianist played good, then it was good regardless of whether the player was African American or white.

Answer:
There are six widely accepted conditions for hurricane development:
1. The first condition is that ocean waters must be above 26 degrees Celsius (79 degrees Fahrenheit). Below this threshold temperature, hurricanes will not form or will weaken rapidly once they move over water below this threshold. Ocean temperatures in the tropical East Pacific and the tropical Atlantic routinely surpass this threshold.
2. The second ingredient is distance from the equator. Without the spin of the earth and the resulting Corioles force, hurricanes would not form. Since the Corioles force is at a maximum at the poles and a minimum at the equator, hurricanes can not form within 5 degrees latitude of the equator. The Corioles force generates a counterclockwise spin to low pressure in the Northern Hemisphere and a clockwise spin to low pressure in the Southern Hemisphere.
3. The third ingredient is that of a saturated lapse rate gradient near the center of rotation of the storm. A saturated lapse rate insures latent heat will be released at a maximum rate. Hurricanes are warm core storms. The heat hurricanes generate is from the condensation of water vapor as it convectively rises around the eye wall. The lapse rate must be unstable around the eyewall to insure rising parcels of air will continue to rise and condense water vapor.
4. The fourth and one of the most important ingredients is that of a low vertical wind shear, especially in the upper level of the atmosphere. Wind shear is a change in wind speed with height. Strong upper level winds destroy the storms structure by displacing the warm temperatures above the eye and limiting the vertical accent of air parcels. Hurricanes will not form when the upper level winds are too strong.
5. The fifth ingredient is high relative humidity values from the surface to the mid levels of the atmosphere. Dry air in the mid levels of the atmosphere impedes hurricane development in two ways. First, dry air causes evaporation of liquid water. Since evaporation is a cooling process, it reduces the warm core structure of the hurricane and limits vertical development of convection. Second, dry air in the mid levels can create what is known as a trade wind inversion. This inversion is similar to sinking air in a high pressure system. The trade wind inversion produces a layer of warm temperatures and dryness in the mid levels of the atmosphere due to the sinking and adiabatic warming of the mid level air. This inhibits deep convection and produces a stable lapse rate.
6. The sixth ingredient is that of a tropical wave. Often hurricanes in the Atlantic begin as a thunderstorm complex that moves off the coast of Africa. It becomes what is known as a midtropospheric wave. If this wave encounters favorable conditions such as stated in the first five ingredients, it will amplify and evolve into a tropical storm or hurricane. Hurricanes in the East Pacific can develop by a midtropospheric wave or by what is known as a monsoonal trough.
Explanation:
One major barrier to entry under pure monopoly arises from the cost of the infrastructure that would be needed for production.
<h3>What is meant by barriers to entry?</h3>
This is the term that is used to show that the market structure is very difficult to break into.
This means that there would be only very few sellers of that particular product in the market.
<h3>What is diseconomies of scale?</h3>
This term is used in economics to refer to the fact that a business or a firm would have grown to be so large in such a way that the costs per unit would have to rise.
This is the stage where the economies to scale is no longer working for this particular firm. The production of goods and services would rise so much as per the unit cost of each item.
Types of these are
- infrastructure diseconomies
- Pollution diseconomies

An error is a misconception that can happen when doing some work that is not concluded accordingly. Some of the errors that concern are gross, random, systematic, and computer errors.
<h3>What are the types of errors?</h3>
Gross error is an error that is unpredictable and is due to s a sudden change because of the operator or the system. While random errors are caused to mistake in observed values.
Systematic errors are the identifiable errors that change the results of the experiment and a computer error is a mistake made by the computer system.
Therefore, random, systematic, computer and gross are the types of errors.
