The correct answer to this open question is the following.
Although the question does not include options, we can answer the following.
A video journalist's job consists of operating the camera, reporting the story, and often editing the work, whereas these three tasks were traditionally performed by three people. Video journalism is an example of job enrichment and job enlargement.
When we talk about job enrichment, this means that the job can be added with different dimensions not considered before. When this happens, the individual can show more enthusiasm and be more motivated for the new responsibilities added to its original job. When you add new dimensions to a job and explain employees the reasons for this and the benefits accompanied with these new responsibilities, you are motivating the employee to work better, harder, and to be more productive.
All but the first one, "Never purchase a warranty."
