The country of Baurisia has, until now, been self-sufficient
in both grain and meat. However, with growing prosperity in
Baurisia 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 per capita income in Baurisia is almost certain to
rise further but increases in domestic grain production are highly unlikely,
Baurisia is soon likely to become an importer of grain.
Which of the following, if true, most seriously weakens the argument?
A. When people increase their consumption of meat,
they also tend to increase their consumption of grain.
B. The per capita consumption of meat in Baurisia is roughly
the same across all income levels.
^^^^^^^^^^^^^^^^^^^^^^^^ 不懂意思 請幫忙解釋!!
C. Per capita consumption of meat has not increased substantially in recent
years in those countries from which Baurisia is likely to import meat.
D. It is more economical for Baurisians to import meat than grain.
E. During Baurisia's years of growing prosperity,
the country's population has remained relatively stable.
答案是D
不過其他選項我不太懂意思
請大大幫忙 解釋 謝謝!!!
