there is no way to produce more of one good
without producing less of the other.
这里的good应该是商品的意思.不是只有Goods是商品吗?单数的good也是商品吗?
全文是：
An outcome is said to be efficient if the economy is getting all it can from the
scarce resources it has available.Points on (rather than inside) the production possibilities
frontier represent efficient levels of production.When the economy is producing
at such a point,say point A,there is no way to produce more of one good
without producing less of the other.Point B represents an inefficient outcome.For
some reason,perhaps widespread unemployment,the economy is producing less
than it could from the resources it has available:It is producing only 300 cars and
1,000 computers.If the source of the inefficiency were eliminated,the economy
could move from point B to point A,increasing production of both cars (to 700)
and computers (to 2,000).
