As dietician for this 300-person school I am concerned about the sudden
shortage of
beef. It seems that we will have to begin to serve fish as our main source of
protein. Even though beef costs more per pound than fish, I expect that the
price I
pay for protein will rise if I continue to serve the same amount of protein
using
fish as I did with beef.
The speaker makes which of the following assumptions?
A) Fish is more expensive per pound than beef.
B) Students will soon be paying more for their meals.
C) Cattle ranchers make greater profits than fishermen.
D) Per measure of protein, fish is more expensive than beef.
E) Cattle are more costly to raise than fish.
