Answer: Option (D) is correct
Step-by-step 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.
