the price of the product itself
In constructing a stable demand curve for product X:
the prices of other goods are assumed constant
Block's sells 500 bottles of perfume a month when the price is $7. A huge increase in resource costs causes price to rise to $9 and Block's only manages to sell 460 bottles of perfume. The price elasticity of demand is:
0.33 and inelastic (The change in quantity is (500 - 460)/(500 + 460) = 0.0417 and the change in price is (7 - 9)/(7 + 9) = 0.125. Elasticity, then is 0.0417/0.125 = 0.33.)

It means there is an opportunity cost when resources are used to provide "free" products
A reduction in the level of unemployment would have which effect with respect to the nation's production possibilities curve?
It would not shift the curve; it would be represented by moving from a point inside the curve toward the curve.
