Lobsters and other crustaceans eaten by humans are more [#permalink]
 19 Feb 2009, 13:49
Question Stats:
0% (00:00) correct
 0% (00:00) wrong based on 0 sessions
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 sewagecontaminated
water as in unpolluted water.
(D) Gill diseases cannot be detected by examining
the surface of the lobster.
(E) Humans often become ill as a result of eating
lobsters with gill diseases.

weakens the argument?
(A) Contaminants in the harbor other than sewage
are equally harmful to lobsters. Out of scope
(B) Lobsters, like other crustaceans, live longer in
the open ocean than in industrial harbors. Possibly strengthen if they die sooner in harbors
(C) Lobsters breed as readily in sewagecontaminated
water as in unpolluted water. Out of scope
(D) Gill diseases cannot be detected by examining
the surface of the lobster. Again I feel that this is out of scope. But seems very close. Possibly there are other methods to detect and avoid eating them
(E) Humans often become ill as a result of eating
lobsters with gill diseases.
It is stated hardly in the stem. Hardly means almost none but not none. So one in a thousand might contract the gill disease and that lobster can get the person/entire family down with gill disease.
Honestly I dont find any thins appealing. But go with E as it looks like the lesser of evil and remotely makes a point

argument says that we shouldnt make an effort to reduce sewage in the harbor because lobsters dont live long enough for that to make a difference.
E says that since we eat the lobsters we will be the ones getting sick

IMO clear E
We look for another problem linked with gill diseases.

My 0.02 The plan is pointless.... WHY? hardly any lobsters live long enough to be harmed by those diseases. - Supported reason is concerned more about harm to lobster. But what if lobsters are carrying gill diseases though disease has not shown any perceivable harm to lobsters?
In that case "harm to lobster" may not be enough reason to defend that plan is "pointless".
