This got me down.
A real great CR for me.

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 of 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, because hardly any lobsters live long enough to be harmed by those diseases.

Which one of the following, if true, most seriously 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 diseases cannot be detected by examining the surface of the lobster.
(E) Humans often ill as a result of eating lobsters with gill diseases.

i thought about 2 minutes and then the reaosn came out..

Its E, i may sound rude to Anumal rights activists :wink: ... but who cares if Lobesters are harmed or not .... if they have gill infections and we eat lobseters, we'll get sick .... so there is a point in dumping sewage in open ocean ....

This is a tough question. I'm not sure I found one that really does what the question asks.

I have no idea. LOL

Under a recent proposal, millions of gallons of 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, because hardly any lobsters live long enough to be harmed by those diseases.

Assumptions:
1) Lobsters caught in the harbor live/breed in the harbor. If they live in the open ocean and walk to the harbor to get caught, then the dumping out in the ocean would certainly be pointless, but not for the reasons mentioned by the stem.
2) Gill Diseases take a long time to make a lobster sick
3) Something in the sewege is causing the sickness (decent assumption, but still an assumption)

Which one of the following, if true, most seriously weakens the argument?
(A) Contaminants in the harbor other than sewage are equally harmful to lobsters.
This actually supports the conclusion. It says that something else is equally harmful meaning that the lobsters will still get infected even if the sewage is sent kilometers out into the ocean.
(B) Lobsters, like other crustaceans, live longer in the open ocean than in industrial harbors.
At first this seems like the right answer because it talks about lobsters living longer, but then I realized it discusses lobsters in the open ocean, not where obsters are caught. Kind of out of scope.
(C) Lobsters breed as readily in sewage-contaminated water as in unpolluted water.
This has to do with the number of lobsters born/spawned(?), not how long they live.
(D) Gill diseases cannot be detected by examining the surface of the lobster.
Huh? Does this even matter? Where does the stem say anything about detecting the diseases?
(E) Humans often ill as a result of eating lobsters with gill diseases.
This actually supports the reasoning. The entire passage would be unnecessary if this were not true.

You're right. I agree with your reasoning. It's a very simple answer and I know I'm not used to looking for simple answers. I guess we should ask ourselves this question:

What answer makes it worthwhile to get rid of the sewage that (as the stem says) causes gill diseases?

If people get sick from eating lobster that has gill diseases due to sewage, then it is not pointless (as the conclusion states) to dump the sewage farther out into the ocean.

This is one of those questions for which the answer was sitting right in front of us.

For a change I did not find this CR difficult :)

Premise :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 of local sewage each day would be rerouted many kilometers offshore.
COnclusion:the proposal is pointless, because hardly any lobsters live long enough to be harmed by those diseases

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


humans get gill diseases from lobsters grown in sewage waters. proposal -reduce pollution becasue losbsters don't live long enough.

Assumption - Lobsters die or eaten before they are affected by the disease. So they cannot pass on to humans.

E weakens that assumption.

It is E,

Obvious that lobsters need not be harmed by contamination, but that contamination when consumed by humans will harm them. So contamination must stop.

Can someone please help understand E.

why A is wrong here.

it is said that the main point is to reroute the sewage water so that water doesnt get polluted.

and A says that even if the water is rerouted , lobsters will get infected because of the other pollutants in water so it is pointless to reroute water. hence it is directly attacking the conclusion.
