Here is the answer explanation:
(A) The only measurements we get in the stimulus are of "fish, by weight." The stimulus
never tells us the absolute number of fish (either in the sea, or being harvested by the industry). Thus, the information in the answer choice is "new information," and we cannot be certain about it.
(B) goes beyond what the stimulus tells us, because we only know what changes the technical sophistication of the industry's equipment experienced, and what those changes enabled, during the years between 1955 and 2000. We do not know what happened to that technical sophistication, or what it enabled, after 2000.
(C) goes beyond what the stimulus states. We only know that the harvest did not increase after 1990. We have no way of knowing if it declined.
(D) goes beyond what the stimulus tells us. We only know what happened to the technical sophistication of fishing equipment between 1955 and 2000. We know nothing about what happened to that sophistication before 1955.
(E) CORRECT ANSWER. For the industry's harvest to stay the same each year from 1990 to 2000, even though it was capturing a greater percentage of the weight of fish in the sea in each of those years, the total weight of fish in the sea had to decline. For example, let's say the industry caught 70% of the weight of fish in the sea in 1990 and 85% of the weight of fish in the sea in 2000. And let's also say that in each of those years the industry had the same total harvest of 1,000,000 pounds. Then the total weight of fish in the sea in 1990 would've been a little over 1.4 million pounds, and the total weight of fish in the sea in 2000 would've been a little less than 1.2 million pounds (a decline).
FINAL ANSWER IS (E)
