The economic term is the opportunity cost.
The concept of opportunity cost is a relatively inexpensive and relative measure that involves people's preferences, so it varies from person to person. It is a question of comparing what is left over when making a decision.
In Katie's case, the opportunity cost of the money she saves to buy a car is what she fails to do with that money. For example, she stops investing in stocks, fails to make a trip, etc.
All decisions involve an opportunity cost. Taking another example, the opportunity cost of studying for the test at the end of the week is measured by the loss of leisure you would have. However, the decision to study for the test is chosen because it is more valuable.
The correct answer is B. Gatekeeping
Explanation:
Gatekeeping refers to the process in which information is summarized, filtered or reduced in a way is understood by a general audience usually because the information is published for the general public. This occurs in mass media as editors, reporters and almost all agents involved cannot include all the information and therefore need to decide on which information will be included and which would be excluded. This occurs in the case presented as all the media sources created a simplified version that can be understood by the general public rather than all the information and statistical data that would be too much to process for the public and too difficult for those without an academical background. Therefore in this case gatekeeping is occurring as information is reduced because it was going to be published for a broad audience.
The correct answer is A. Working conditions
Explanation:
Frederick Herzberg's two-factor theory claims that one of the two main factors causing dissatisfaction in employees is hygiene factors. These factors are related to general working conditions, payments, and benefits, status, among others that depend mainly on the employer and the policies of the company. Moreover, hygiene factors differ from motivators (the second factor in the theory) because motivators are related to recognition, promotion, and similar that depend on the employers but also the performance of employees.
According to this, the factor that would be considered a hygiene factor is "working conditions" because this factor includes elements such as an old or inadequate building that depend mainly on the employer, which is a characteristic of hygiene factors. Also, other factors such as promotion, training or recognition are part of motivators rather than hygiene.
