To reduce the danger to life and property posed by major earthquakes, scientists have been investigating several techniques for giving advance warning of dangerous earthquakes. Since catfish swim erratically before earthquakes, some investigators have proposed monitoring catfish to predict dangerous earthquakes.

Which of the following, if true, most seriously undermines the usefulness of the proposal?

(A) In Japan, which is subject to frequent earthquakes, the behavior of catfish has long been associated with earthquakes.
(B) Mechanical methods for detecting earthquakes have not proved effective.
(C) Tremors lead to the release of hydrogen sulfide gas into water, thereby causing various fish and shellfish to behave erratically.
(D) Careful construction can reduce the dangers posed by earthquakes.
(E) Even very slight, fleeting tremors cause catfish to swim erratically

To prevent damages caused by earthquakes, scientists will rely on catfish because they swim erratically before earthquakes.

Which of the following, if true, most seriously undermines the usefulness of the proposal?

We have to look for an answer that undermines the connection earthquake => movement of catfish.
E does just that:
(E) Even very slight, fleeting tremors cause catfish to swim erratically
The connection in undermined now

Initially I was quite sure of C, so I want to explain why I discarded it eventually:
(C) Tremors lead to the release of hydrogen sulfide gas into water, thereby causing various fish and shellfish to behave erratically.

well i think all the choices but E are helping to explain as why this plan can work
E sud be the answer coz conclusion is abt the dangerous earthquakes but E tells us that even minor tremors can cause these fish to behave erratically !! so the plan is useless

Hi Zarr,

Choice (E) Even very slight, fleeting tremors cause catfish to swim erratically

Can't we infer that in case of dangerous earthquakes, definitely the cat fish would SWIM erratically?

And hence the proposal of monitoring the CATFISH to predict dangerous earthquakes is strengthened rather than weaken.

My 2 cents, I think answer lies within the story "The Boy Who Cried Wolf"
Joke apart.. idea is to find a reliable solution for giving advance warning abt dangerous earthquakes to people.
Now if scientists are relying on a source, which behaves similarly in 2 different situations then how would they decide whether its time to alert ppl abt the major earthquake or not.

Argument talking about dangerous earthquake and E undermines this argument saying that its not accurate and misleading.

I think C at first looks very obvious, but the wording the answer choice involves is tricky. It says that Tremors lead to release of Hydrogen Sulfide..... This is a trap.... we have to assume here that scientists have no method to find the release H2S gas. Then and then only we can move forward. This assumptions makes this choice wrong and also the fact that other fish behave erratically is Inconsistent.

(A) In Japan, which is subject to frequent earthquakes, the behavior of catfish has long been associated with earthquakes. Strengthener

(B) Mechanical methods for detecting earthquakes have not proved effective. Out of scope

(C) Tremors lead to the release of hydrogen sulfide gas into water, thereby causing various fish and shellfish to behave erratically. Out of scope

(D) Careful construction can reduce the dangers posed by earthquakes. Out of scope

(E) Even very slight, fleeting tremors cause catfish to swim erratically. Correct.

Correct me if I'm wrong

I think if we consider what option E is saying, even a small tremor can cause the catfish to swim erratically. This will make the system even more precise as the system will be able to detect even a very small earthquake. This will strengthen the authors claim.
