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 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 accross all income levels.
(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.

Option (D) is correct

Explanation:

To weaken the conclusion, the answer will emphasize on why Baurisia will not soon become an importer of grain.  

Here, in this case if importing meat is cheaper than importing grain, then Baurisia is likely to satisfy the demand for meat by becoming an importer of meat, weakening the conclusion that Baurisia will soon become an importer of grain.  

Therefore , It is more economical for Baurisians to import meat than grain, if true, most seriously weakens the argument.

the correct answer is economics is a game without winners or losers.

unlike sports or games economic is a game without losers or winner rather it is a game where everyone wins. parties of business doing businesses exchange money with each other and hence exchange is done on the basis of goods. one party takes the goods and other sales it so there is winner on both sides. each party values more highly the good it gets than the good it gives up. both sides exchange only because both intend to increase their value. so there is no concept of lose or win.
