Multiple Choice

Table 1.3 shows the hypothetical trade-off between different combinations of brushes and combs that might be produced in a year with the limited capacity for Country X,ceteris paribus. Table 1.3
Production Possibilities for Brushes and Combs
$\begin{array}{|l|r|c|c|c|}\hline \text { Combination } & \begin{array}{c}\text { Number of } \\\text { Brushes }\end{array} & \begin{array}{c}\text { Opportunity Cost of } \\\text { Brushes in Terms of } \\\text { Combs }\end{array} & \begin{array}{c}\text { Number of } \\\text { Combs }\end{array} & \begin{array}{c}\text { Opportunity Cost of } \\\text { Combs in Terms of } \\\text { Brushes }\end{array} \\\hline \mathrm{J} & 0 & & 4 & \\\hline \mathrm{K} & 10 & & 3 & \\\hline \mathrm{L} & 17 && 2 & \\\hline \mathrm{M} & 21 & & 1 & \\\hline \mathrm{N} & 23 & &0 & \\\hline\end{array}$
