Answer the Question on the Basis of the Following Production

Answer the question on the basis of the following production possibilities data for two countries,Alpha and Beta,which have populations of equal size. $\begin{array}{c}\quad\quad\underline{\text { Alpha's Production Possibilities }}\\\begin{array}{lll} \\ \text {Fish (Tons) }\\ \text {Chips (Tons) } \end{array}\begin{array}{c}\underline{\text {A }}\\ 80 \\0\end{array}\begin{array}{c}\underline{\text {B }}\\ 60 \\5\end{array}\begin{array}{c}\underline{\text {C }}\\ 40 \\10\end{array}\begin{array}{c}\underline{\text {D }}\\20 \\15\end{array}\begin{array}{c}\underline{\text {E }}\\0 \\20 \end{array}\end{array}$

$\begin{array}{c}\quad\quad\underline{\text { Beta's Production Possibilities }}\\\begin{array}{lll} \\ \text {Fish (Tons) }\\ \text {Chips (Tons) } \end{array}\begin{array}{c}\underline{\text {A }}\\240 \\0\end{array}\begin{array}{c}\underline{\text {B }}\\ 180 \\10\end{array}\begin{array}{c}\underline{\text {C }}\\120 \\20\end{array}\begin{array}{c}\underline{\text {D }}\\60 \\30\end{array}\begin{array}{c}\underline{\text {E }}\\0 \\40 \end{array}\end{array}$
