Guys, try this!

(PR Real LSAT)

Lobsters and other crustaceans eaten by humans are more likely to contract gill diseases when sewage contaminates their water.
Under a recent proposal, millions of gallons local sewage each day would be rerouted many kilometers offshore. Although this would substantially reduce the amount of sewage in the harbor where lobsters are caught, the proposal is pointless, bacause hardly any lobster live long enough to be harmed by those diseases.

Which of the following, if true, most seriosly weakens the argument?

A) Contaminants in the harbor other than sewage are equally harmful to lobsters.
B) Lobsters, like other crustaceans, live longer in the open ocean than in industrial harbors.
C) Lobsters breed as readily in sewage-contaminated water as in unpolluted water.
D)Gill diseas cannot be detected by examining the surface of the lobster.
E)Humans often become ill as a result of eating lobsters with gill diseases.

OA later!

Tough one..

Nothing seems to be right.

A - supporting the argument by giving one more point which says the proposal is pointless

D,E - Out of scope choices

C - would be right if we have taken one more assumption about "breed".

close one

B - saying that Lobsters, like other crustaceans, live longer in the open ocean than in industrial harbors.

which opposes the assumption of CR. clearly, the best in given choices..

Correct me if i am wrong.

What's the OA.

To syamee_u and mba,

Not B.

Your "chain" of reasoning is about the same as mine, but I picked up another choice and was puzzled by OA.

The book I am using doesn't provide an explanation. Hence, I decided to post this CR.

Guys, other thoughts?

IMO B and E are the contenders. But B is talking about industrial pollution affecting the lobsters.
E is better because the lobsters are carriers of disease and die before it affects them. They will die anyway because humans eat them. If Humans get affcted then it is a bad thing and the proposed plan of diverting sevage is indeed required.
Hence it weakens authors argument.

The conclusion say that hardly any lobster live long enough to be harmed by those diseases.

To me BC are out of scope. A I think is confirming the arg.

D although not perfect maybe the best here. E somehow is a restatement of one of the premises, although I think it is the second best contender.

IMHO, I pick D because if the only way to know that a lobster is contracted by gill desease is by examining the inside then how could you conclude that they are contracted by the desease after a certain age/ live period. (unless each lobster caught is physically opened and checked medically). Indeed they maybe dont live long because of the desease and by the time you find out they may already die.

but i dont know cr qs from other sources than official gmat and lsat can be strange sometimes.

OA is "E".

Picked up "C" I was shocked seeing OA. I thought "D" and "E" are out of scope :(

Even after anandnk's and aonie's explanations "E" seems to be strange for me.

Hi anand,

could you please elaborate your explanation.

I still think B is the best choice.

And this CR is completely strange with provided choices.

E is really puzzling choice.

contracting disease is not same as getting affected by it. So the life of lobsters is not important because they are going to die anyway as humans eat them.
A lobster might contract a disease and might take some time for it to have symptoms. If humans catch them and eat them before they develop the disease then we should see if humans are affected.

Author is saying that there no benefit of diverting sevage water because he/she is concerned about development of disease. Well the lobsters die in anycase before symptoms are seen but go on to affect humans. Hence it is necessary to diver the water.

So E is the best.

Alright E it is... I thought it was between D and E but because in LSAT questions E looks like a choice that normally serves as a trap because it merely a re-statement of the argument premises.

B) Lobsters, like other crustaceans, live longer in the open ocean than in industrial harbors.
C) Lobsters breed as readily in sewage-contaminated water as in unpolluted water.
D)Gill diseas cannot be detected by examining the surface of the lobster.
E)Humans often become ill as a result of eating lobsters with gill diseases.

The bold part is the main conclusion. Answer choice E prove that the proposal is effective if people eat less contaminated grilled lobster. Hence, weaken the argument.

Lobsters are more likely to contract gill diseases when sewage contaminates their water.
Under a recent proposal, millions of gallons local sewage each day would be rerouted many kilometers offshore.(away from offshore)
Although this would substantially reduce the amount of sewage in the harbor where lobsters are caught, the proposal is pointless, because hardly any lobster live long enough to be harmed by those diseases.

Which of the following, if true, most seriously weakens the argument?

A) Contaminants in the harbor other than sewage are equally harmful to lobsters...............other than sewage is out of concern. OFS
B) Lobsters, like other crustaceans, live longer in the open ocean than in industrial harbors.............can be true but this does not determine whether they live long enough to be harmed.
C) Lobsters breed as readily in sewage-contaminated water as in unpolluted water.............breeding does not give any info regarding survival.
D)Gill diseases cannot be detected by examining the surface of the lobster.......whether the diseases can be detected or not falls outside of the scope of argument.
E)Humans often become ill as a result of eating lobsters with gill diseases...........so removing the sewage will help reduce the incidence of disease and thus is helpful and not pointless.
