Explanation:

A large body of evidence is dedicated to elucidating the relationship between pain and stress. Numerous prospective studies have reported baseline anxiety scores to be significant predictors of pain, depression, and a reduced quality of life. Importantly, pain itself is a stressor, and a maladaptive response to acute pain may intensify the pain experience and condition a sensitized physiologic stress response to pain-provoking stimuli. Exaggerated, prolonged, or recurrent activation of a sensitized stress response to pain or non–pain-related stressors may initiate or exacerbate pain and disability. Although the relationship between pain and stress is widely accepted, the underlying neuroendocrine mechanisms involved are less understood.

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.
