Russia's aggressive fishing in the prime fishing grounds of the Northern Pacific has led to a sharp decline in the populations of many fish and a general increase in the retail price of fish. This same pattern has occurred with far too many of our scarce vital natural resources, resulting in high prices for many products. It is likely then, that fish prices will continue to rise in the near future.
In making the argument above, the author relies on all of the following assumptions EXCEPT:
(A) The scarcity of fish is a determining factor in its price
(B) The decline in the number of fish available will result in higher prices for fish in stores.
(C) There will not be any substantial decrease in other costs involved in the fishing process that could keep the price of fish from increasing.
(D) Fish populations will not recover in the near future.
(E) Fishing practices can substantially influence the demand for fish.
The author argues that because Russian overfishing has caused fish populations to decline and prices to rise, and because this pattern of overexploitation leading to high prices has happened with other resources, fish prices will likely keep rising.
(A) The argument's logic depends on scarcity driving price. Assumed.
(B) The author explicitly states the decline has increased retail prices and expects this to continue. Assumed.
(C) The argument assumes no offsetting cost decreases (e.g., cheaper fuel, labor) that would prevent price increases. Assumed.
(D) If populations recovered quickly, prices might not rise. The prediction of rising prices assumes no near-term recovery. Assumed.
(E) The argument is about supply (fishing practices affect fish populations), not demand. Whether fishing affects demand for fish is irrelevant to the price-increase prediction. The author only assumes supply-side effects.
NOT assumed. The author's reasoning centers on supply scarcity raising prices. Assumption E shifts to demand, which is not part of the argument's logic. Therefore,
the answer is E.
