A good way to work out the kinks of an experiment is to Group of answer choices conduct a pilot study. write an IRB proposal. engage in step-by-step visualization of the research procedure. have someone else read the procedure section of your paper.

answer; /// i believe that the correct answer is (a) making presentations;

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 !
