Question

A worker's success in contributing to the common good is 

       A. measured by how well she or he does the job.   B. determined by their supervisor.   C. increased when she or he becomes a supervisor.   D. greater in vertical relationships.

Answer 1

A worker's success in contributing to the common good is A. measured by how well she or he does the job.  
I believe this is the best option given that it is nonbiased and relatively objective. By taking a look at the results that a particular employee has achieved, the supervisor will know whether or not they were successful and contributed to the company.

Answer 2

A worker's success in contributing to the common good is  measured by how well she or he does the job.

Explanation:

The common goal is the objective that the organization wants to achieve with the help of its employees. Every organization tries to motivate its employees or workers so that they can provide better output for the organization. The contribution should directly impact the productivity of the company.

Here, option A is correct because of all other options being an example of personal growth or development of a worker or employee such as becoming a supervisor, this could have a direct impact on the employee's life and personal goals but its not directly related to the common goal that the organization wants to achieve.
