In theory, Papua New Guinea (PNG) could be a substantial exporter of tropical crops. In actuality, it is not. The reason is that 97 percent of all land is owned by clans and cannot be bought or sold by individuals, and thus the kinds of realignment of properties that would be necessary to achieve maximum production for export have been impossible to achieve.
The answer to which of the following questions would be most relevant to evaluating the adequacy of the explanation given above?
(a) Who owns the 3 percent of the land in Papua New Guinea that is not owned by clans?
(b) What percentage of PNG's current production of tropical crops is consumed within the country?
(c) How much longer is land ownership by clans expected to remain the prevailing cultural pattern in PNG?
(d) Which of the tropical crops currently grown in PNG could be exported if there were a surplus for export?
(e) How does PNG's current production capacity for tropical crops compare with the maximum capacitythat property realignment would make possible?
