Specialization increases productivity which is good for the producers. Consumers have more options, since there are more products on the market. Specialization also contributes to better quality of production and the final products because in the chain of production each employee is specialized in doing one thing in the best way.
        
             
        
        
        
Answer:
Explanation:
The Bessemer process was invented by Henry Bessemer and was used for the production of steel from molten pig iron.
The Bessemer process had the following advantages:
1. Steel could now be produced in bulk
2. The process of making steel became less labor-intensive
3.Due to its small and compact size, major repairs can be carried out within short periods of time 
Shortfalls of the Bessemer process:
1. The Bessemer process was not able to remove the phosphorous found in the Pig iron of some types effectively, thus making it inefficient in that aspect
2. Steel produced through the Bessemer process always had retention of a small amount of Nitrogen from the air blast which adversely affected its structural stability and longevity when used for construction.
3. The Bessemer process usually produces inferior quality steel associated with blow holes and inclusions

Answer:The theory of compensating wage differentials
Explanation:
The theory of compensating wage differentials is theory that explains the differences that occurs in wages between people. 
When everything else is the same a high rate pay may refer to the fact that the job may be less attractive so since the job may be undesirable a compensating wage may be used to make up for this in order to pursued people to accept the job or as an encouragement to change their mind and consider the offer that may seem unattractive. 
 A compensating differential can also occur in a desirable job but it won't be positive in this case because when a job is desirable a potential employee may willingly take the job even if it offers lower wages just because it is desirable
 
 Working in a coal mine has many undesirable features that may not attract someone to it hence may have to explain the high wages and being a secretary may be attractive or may be a compromise for Jasmine in the lack of available jobs.
