The shape of a production possibility curve is downward-sloping because . Select the correct answer below: you can get more of one good only by giving up some of another good quantities produced are always negative you cannot get any more of good, even by giving up some of another good none of the above

you can get more of one good only by giving up some of another good

Explanation:

A production possibilities frontier shows the opportunity cost of producing one good instead of another. This way, as you follow the curve, the combination of goods will vary, increasing the production of one good but deceasing the production of the other.

Opportunity costs are the benefits lost or extra costs associated to choosing one activity or investment over another alternative. Since resources are scarce, you must always give something up in order to obtain another thing, e.g. you give up your leisure time in order to study.
