In 1992 Outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia. Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there beging no reduction in the level of legal lobster fishing activity, the local catch was 9,000tons below pre-1992 levels. It is therefore highly likely that the outlaw fishing boats harvested about 9,000tons of lobster illegally that year.

Which of the following is an assumption on which the argument depends?

A. THe illegal lobster harvesting was not so extensive that the poplulation of catchable lobsters in Belukia's territorial waters had sharply delined by 1996.
B. The average annual lobster catch, in tons, of an outlaw fishing boat has increased lobster-fishing boats.
C.Outlaw fishing boats do not , as a group, harvest more lobsters than do licensed 9,000 tons.
D. The annual lobster harvest in Belukia in 1996 was not significantly less than 9,000tons.
E. A significant proportion of Belukia's operators of licensded lobster-fishing boats went out of business between 1992 and 1996.

It should be A

A states that the Quantity of Fishes is more or less the same in 92 & 96.
This assumption is really required.

A is the best; it emphasizes that the A(the legal catch)+B(illegal catch)= A(legal catch in 1992)+B(legal catch in 1992) only if B did not decrease because of overfishing by 1997.

I had D as a contender as well, but eliminated it after reading A. Moreover, the illegal catch does not contribute to the country's annual output (hopefully !!!)

ans A.

A is the necessary assumption,nowhere in argument they focussed on lobster overall population.
and linked decline in lobster catch ---> decline in illegal catch of lobster.
so they definately assumed that the overall population of lobster has been constant .

Agree with A. The lobster population would need to remain the same in 1996 as 1992 in order to make the argument work.

I don't understand why D would be an option. The total harvest shouldn't matter. I think D says the harvest did not reduce by more than half, right?

The way I read the statement, is that in 92, the illegal lobster pirates, started eating into the legal lobster harvest, and thus decreasing the legal lobsters. The point of the argument, is that how ever many illegal lobsters are pulled out of the water, the legal lobsters harvest decline by exactly that amount. Thus if legal lobsters declined by 9000 tons in 96, then there must have been 9000 tons of illegal lobsters that year.

But there could be other reasons for the legal lobster decline. Such as the illegal lobster pirates fished out of the water so much between 92 and 96, that there are simply not as many lobsters any more. But A says that definitely did not happen. The argument depends on this definitely not happening.

Still waiting on OA please!

Does this mean that the lobster couldnt breed and grow in population in 96?

Argument says: LEGAL lobster catching was as usual but still 9000 tons less harvest.
Conclusion: Outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.

This is still confusing.

Um yeah, it's still confusing cause I still do not see the OA! Please post danji628.

"A" says that the population, whether they breeded or not, did not sharply decline. If you do not agree with "A" what do you think the answer is? The other ones do not work for me at all, and you only need to pick the best answer, not the most perfect answer.
