When the house and the senate pass two different versions of a bill, a reconciles them into a single version to be presented to the president for his signature (or veto).

Conference Committee

Explanation:

When the House and the Senate pass different versions of a bill, a Conference Committee can be convened. The Conference Committee is a temporary panel in which representatives of both chambers work together to reach a compromise and reconcile their differences over a bill into a single version.

If a compromise is reached, the "managers" (the conferees) prepare a conference report and then they send it to each chamber. Once the conference report is approved by the chambers, the bill is sent to the President for signature so that it can become a law.

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 !

i think it is the third one.
