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 being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels. It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons 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 population of catchable lobsters in Belukia’s territorial waters had sharply declined by 1996.
B. The average annual lobster catch, in tons, of an outlaw fishing boat has increased steadily since 1992.
C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats.
D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons.
E. A significant proportion of Belukia’s operators of licensed lobster-fishing boats went out of business between 1992 and 1996.

A. The illegal lobster harvesting was not so extensive that the opulation of
catchable lobsters in Belukia’s territorial waters had sharply eclined by 1996. Yes this is it..As we know that legal catch has not increased and option tell that the population of lobsters has not declined so therefore it is only possible then that illegal catch was 9000..

B. The average annual lobster catch, in tons, of an outlaw fishing boat has increased steadily since 1992. Nothing mentioned related Avrg catch by outlaw fishing boats out of scope

C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats. Out of scope

D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons. Irrelevant

E. A significant proportion of Belukia’s operators of licensed lobster-fishing boats went out of business between 1992 and 1996. Out of scope as it is already mentioned that there is no decline in legal catch

Premise: illegal lobster harvesting began in 1992.
Premise: legal catch was 9k tons below pre-1992 levels.
Conclusion: it is highly likely that illegal harvest was about 9k tons.

A defends the conclusion by eliminating the possibility that lobster population may have decreased because of rampant harvesting

since assumption strengthens the conclusion .. its logical negative should weaken the conclusion

logical negative of A: illegal harvest was so extensive that lobster population sharply declined.

the logical negative clearly weakens the conclusion .. and passes the test

A is correct

Another +1 for A.

Negating A, we realize that the levels have already been reduced so much that the reduction in tonnage is not due to the harvesting by the illegal guys.

In short there simply was not enough lobster post-1996.

Cheers,

Clear A , reduction is catch is attributed to illegal harvesting , but what if the population is itself declining , then the attribution to illegal harvesting doesnt hold , not a 700 level question

The author is assuming that the lobster population has not declined since 1992.

Superb question , To answer this, full proof reading of the argument is reqd.

despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels. It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.

The highlighted part of the argument implies that despite extensive legal lobster harvesting the number fell only to 9000, that means the author was expecting it to fall by a huge margin.......Hence, the illegal harvesters did not do much damage to the lobsters population, that is the reason, why, even after extensive harvesting the number fell just to 9000

Hence the answer must be A!!!

A. The illegal lobster harvesting was not so extensive that the population of catchable lobsters in Belukia’s territorial waters had sharply declined by 1996.
If this is negated, the argument falls apart - Hence A) If it has declined the argument that the gap of annual catch between 1992 and 1996 can be attributed to illegal catch.

B. The average annual lobster catch, in tons, of an outlaw fishing boat has increased steadily since 1992. -Out of scope as we are talking about the 1996 illegal catching of lobsters.

C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats. - We are not comparing the legal and illegal catch

D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons. - Lets say it is 4k tons. The argument doesn't break or support the argument.

E. A significant proportion of Belukia’s operators of licensed lobster-fishing boats went out of business between 1992 and 1996. - it doesn't affect the argument as per the premise - "despite there being no reduction in the level of legal lobster fishing activity"

I pick A)

Hi e-gmat,

I am not able to get this one.

(A). says that the illegal harvesting was not so extensive that the population of catchable lobsters declined by 1996.

Conclusion: Attributes 9000 fall to illegal harvesting.

Even if I negate (A) that illegal harvesting was so extensive that the population of catchable lobsters declined by 1996.

That is what we are arguing in conclusion that illegal harvesting is the cause for the figure 9000 fall in 1996.

The conclusion of the argument is that the outlaw fishing boats are highly likely to harvest about 9,000 tons of lobsters in Belukian waters in 1996.
The basis for this claim is that:
1. In 1992, outlaw fishing boats started to harvest lobsters in this area
2. After that, the annual volume harvested of lobsters declined.
3. In 1996, the annual volume harvested of legal fishing boats declined by 9,000 tons in comparison to the pre-1992 levels.
4. In 1996, the legal fishing activity is not reduced.
Then the writer must assume that the total volume of lobsters which can be harvested in 1996 is about the same as in pre-1992.
A - CORRECT. If it's true, then there is another reason why the level of lobsters harvested by the legal fishing boats have declined by 9,000.
B - This has no impact on the conclusion.
C - This has no impact on the conclusion.
D - Not relevant
E - Out of scope.

A. The illegal lobster harvesting was not so extensive that the population of catchable lobsters in Belukia’s territorial waters had sharply declined by 1996.

Note: Cachable doesn't mean catched lobsters. Option is talking about total population from which both legal and illegal catches are executed.
So, if legal harvesters couldn't get them, who got them? That's right! --> Illegal Harvesters.

Answer Choice A is correct.

This was a tough nut for me to crack. Alternatively, I would rather solve it by elimination.

B. The average annual lobster catch, in tons, of an outlaw fishing boat has increased steadily since 1992.
Whats steadily? Like 1 ton per year? Would that be enough! NO!

C. Outlaw fishing boats do not, as a group, harvest more lobsters than do licensed lobster-fishing boats.
Again! Harvest how much more? No information!

D. The annual legal lobster harvest in Belukia in 1996 was not significantly less than 9,000 tons.
Argument is comparing the difference. Not absolute values of the catch.

E. A significant proportion of Belukia’s operators of licensed lobster-fishing boats went out of business between 1992 and 1996. I fell them, but this makes no difference.

And we are left with A.

Hi @Egmat@

Although I selected the Choice A, as this is the only option that I found alright, I am not able to understand the argument AT ALL.
Please somebody help me understand the argument.
Does it mean that

Before 1992......> Total local catch = legal catch
1992-------------> local catch = illegal +legal
1996................> same

then in 1996, the legal catch was same, total local catch was below 1992 levels by 9000.
so, in 1996, illegal catch must be 9000.
So....if we say that x is the legal catch which has not changed, in 1992, catch was 18000+x...
so what next?? I am lost..
