Harry produces 8 balloon rides and 9 boat rides an hour. Harry could not produce more balloon rides without producing fewer boat rides. Is Harry producing on his production possibilities frontier? Harry is __ his production possibilities frontier. A. producing on B. moving along C. producing inside D. producing outside

## Step 1<br />The problem is about the concept of the Production Possibilities Frontier (PPF). The PPF is a curve that is used in economics to represent the maximum combination of two goods that can be produced given available resources. <br /><br />## Step 2<br />In this case, Harry is producing 8 balloon rides and 9 boat rides an hour. The problem states that Harry could not produce more balloon rides without producing fewer boat rides. This means that Harry is operating on the PPF, as he is producing at a level where he cannot increase the production of one good without decreasing the production of the other.<br /><br />## Step 3<br />Therefore, Harry is producing on his production possibilities frontier.
