The country of Rowolia has, until now, been narrowly self-sufficient in both grain and meat. However, with growing prosperity in Rowolia has come a steadily increasing per capita consumption of meat, and it takes several pounds of grain to produce one pound of meat. Therefore, since Rowolian per capita income is almost certain to rise further and increases in domestic grain production are highly unlikely, Rowolia will soon need to import grain. Which of the following is an assumption on which the argument depends?The argument says higher income will increase meat consumption, and producing more meat requires more grain. Since domestic grain production is unlikely to increase, Rowolia will need to import grain.
The argument assumes that Rowolia will satisfy the extra demand for meat by producing more meat domestically, not by
importing meat directly.
A. When people’s consumption of meat increases, their consumption of grains and other foodstuffs tends to fall.
This is not required. Even if direct grain consumption falls somewhat, the argument is about the grain needed to produce additional meat.
B. Future demands for meat by Rowolians over and above current consumption levels will not be satisfied by the importation of meat from other countries.
This is correct. If Rowolia imports meat instead of producing the extra meat domestically, it may not need extra grain to feed animals. So the argument depends on assuming that future extra meat demand will not be met through meat imports.
C. There are currently no laws in Rowolia prohibiting the importation of meat from abroad, nor will such laws be enacted in the near future.
This is not required. In fact, if meat imports are allowed, that could weaken the claim that Rowolia must import grain.
D. The per capita consumption of meat in Rowolia is roughly the same across all income levels.
This is irrelevant. The argument needs only the trend that rising income leads to more meat consumption overall.
E. In Rowolia, meat is subject to strict government price controls but grain is not.
This does not matter. The argument is about grain demand caused by meat production, not about price controls.
