Answer:
Predictive validity.
Explanation:
A Predictive validity test is the test that is taken to predict the future performance of the applicant based on the scores in the test. The test is useful in predicting the future, as suggested by the name.
The tests that are taken before allowing a person in any organisation are often predictive. A pre-employment test is such example.

So, the correct answer is predictive validity.
The answer is
A. when aggregate income is high, people hold cash to buy goods that are plentiful and cheap.
Because this factor normally varies, the most important variable that influences the diffusion of respiratory gases is the concentration gradient. The air in the lungs has a higher concentration of oxygen than that of oxygen-depleted blood and a lower concentration of carbon dioxide. This concentration gradient allows for gas exchange during respiration.
Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of higher concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs.
Ventilation maintains concentration gradients of oxygen and carbon dioxide between the air in the alveoli and blood flowing in adjacent capillaries.

Social stratification does not exist in band societies (among others) because: they do not want the system.
<h3>What is social stratification?</h3>
This can be defined as the system where the society is in stratas. By stratas, it means that there is a form of social class in the society.
