Imagine you are tasting bowls of soup for a chef who is working on a soup recipe, and she wants the soup to have a subtle hint of black pepper flavor. In her first batch of soup, you could not detect any pepper flavor. If she cooks several more batches of soup and keeps increasing the amount of black pepper in every batch until you finally notice the black pepper flavor, which psychophysical method is she employing?

Method of constant stimuli

Explanation: The chef is employing psychophysical method of constant stimuli.

Constant stimuli is one of the three psychophysical method, it depicts the sensory threshold by randomly presenting varying degrees of stimuli believed to have close proximity to the desired threshold.

Thus, in the chef scenario, her desired threshold was a subtle hint of black pepper flavor in a soup. Then, she continue to increase the amount of black pepper (i.e random presentation of stimuli) in her batches of soup, until she established a close proximity to her desired threshold (a subtle hint of black pepper flavor in a soup).

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
