The technical sophistication of fishing equipment increased steadily from 1955 through 2000, which enabled the fishing industry to harvest a greater percentage of the total amount of fish, by weight, in the world's oceans in each succeeding year during that time. The fishing industry's harvest, by weight, increased steadily from 1955 until 1990 but did not increase after 1990.
If the statements above are true, which one of the following must also be true?
A) After 1990, the number of fish harvested each year by the fishing industry increased, but the average weight of each fish harvested decreased
B) After 2000, improvements in fishing equipment did not enable the fishing industry to harvest a greater percentage of the total amount of fish, by weight, in the world's ocean
C) The fishing industry's harvest, by weight, was significantly lower in 2000 than it was in 1990
D) No significant improvements in fishing equipment occurred before 1955.
E) The total amount of fish, by weight, in the world's ocean decreased during the period from 1990 through 2000

Chose A because others are either irrelevant or have diverted focal point.
What's the source..??

I chose A.
B&D out since the passage no where talks or provides info about periods prior to 1955 or after 2000.
C out since the passage states that the harvest after 1990 did not increase but that does not imply it decreased.
E out since there is nothing in the passage to suggest that the percentage harvest increased only due to reduction in total amount of fish in the ocean.
It can be very well possible that harvesting growth rates outstripped the growth in total amount of fish in the oceans thus leading to a plateau in the overall catchment after a point of time (and passage suggests the same that increase in harvest did not occur after 1990)
I didn't find any strong reason to accept A either.
Quite confused about this question. Experts help please!

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)
