Given below is a production possibilities combination of a hypothetical economy producing under conditions of efficiency, contact technology, and constant level of resources. The economy is faced with 6 possible production alternatives as follows:

Products Combination Comb. Comb. Comb. Comb. Comb.

A B C D E F

Lobsters 0 1 2 3 4 5

Coconuts 35 33 29 23 15 0

Based on the given table, answer the following questions thoroughly:

(A) Construct the PPC (production possibilities curve) on a graph. For consistency, place the quantity of lobsters along the horizontal axis and the quantity of coconuts on the vertical axis. Axes must be labeled properly. Make sure your axes are calibrated correctly to ensure your PPF comes out right.  Use Excel to derive your graph.

(B) From alternative B to C, what is the opportunity cost of producing the additional unit of lobsters?

(C) From alternative E to F, what is the opportunity cost of producing the additional unit of lobsters?

(D) On the PPF graph, legibly mark a combination that is deemed to be "attainable but inefficient." Mark that combination as point 'X.'

(E) On the PPF graph, legibly mark a combination that is deemed to be "unattainable but desirable." Mark that combination as point 'Y.'
