I think it is a tricky question, but we have to find an answer that "MUST BE TRUE"; it means that nobody can´t say it is incorrect with the statement given. Look at D, can someone says it is incorrect? Not because the statement clearly states it occur. Now look at E, the statement says anything obout it, thus it can be true!

According to me what explanation bb61 gave is more logical.

It says 'Either A or B' indicates - only A or only B or both A and B.

So option of both A and B are still open and the stimulus does not infer option E specifically.

Hence E is eliminated and option D is the best answer choice.

Hope this helps.

Is there any way to check this?
Either A or B.... sure it can also mean both A and B?

Answer is D, as among all the options only D can be proved from the argument.
D. The waters off Papua New Guinea are generally hospitable to eels.
>>"Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel. "

Why C is wrong:
C. Some fish with cartilaginous skeletons are not sharks.
>>scientists are still unsure as to the fish's precise classification, but they agreed immediately that the most logical classification would be as either a shark or an eel.So,
the fish's precise classification is still not done.

A new species of fish has just been discovered living in great numbers in the waters off Papua New Guinea. The fish exhibits some characteristics belonging to sharks, such as a cartilaginous skeleton. However, the fish also exhibits characteristics belonging to eels, such as a long, snake-like body. Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel. But the cartilaginous skeleton puzzles them, since no known eel possesses one. So scientists are still unsure as to the fish's precise classification, but they agreed immediately that the most logical classification would be as either a shark or an eel.

The statements above, if true, most strongly support which of the following?

A. To be placed into a certain classification, a fish must possess all the characteristics of that classification.

B. Physical characteristics, such as skeletons, are scientists' primary means of classifying new species.

C. Some fish with cartilaginous skeletons are not sharks.

D. The waters off Papua New Guinea are generally hospitable to eels.

E. A fish cannot be both a shark and an eel.

The conclusion says that a fish can either be characterized into shark or eel. And, this means that a fish can not be placed in both shark and eel category.

out of B and E selected B. went horribly wrong.

OE given by Kaplan.
[Reveal] Spoiler:
Conclusion: This is an inference question that asks us to draw a conclusion from the information provided. What must also be true given the stimulus?

Evidence: Since we need to draw our own conclusion, we can use all facts provided in the argument as evidence.

The first sentence states that the new fish was discovered off the waters of Papua New Guinea. In addition, the sentence 4 states that the new fish shares its habitat with the eel. In combination, these two sentences indicate that eels also live in the waters off Papua New Guinea. So this region must be hospitable to eels, as stated in (D).

(A) doesn't follow from the information given. The last sentence implies that the new fish could be classified as a shark even though it does not have a cartilaginous skeleton Also, it is extreme in its use of the word all. With (B), the importance of physical characteristics relative to other characteristics is not discussed. With (C), if the new fish were to be classified as an eel, then we could conclude that at least one fish with a cartilaginous skeleton is not a shark. The stimulus, however, never says this. Furthermore, we aren't told anything about other fish classifications. And with (E), the last sentence states that the new fish will probably be classified as either a shark or an eel, but suggests nothing about an animal being both. Though this choice may seem true, we don't know for certain.

Though this choice may seem true, we don't know for certain.

B can not be the correct inference because of 2 words : "new species" and "primary" both these words are very particular in their meanings while the argument nowhere talks about what is the primary method of classification or whether ALL species are classified in this way.

E also uses the same trap of talking about a thing that "might be true" but is always true? We cant say based on just 1 example of the given species in question.Not talking about a species that might be both eel and a shark does not mean that it doesn't exist or at least is not mentioned such.

Such options that talk about absolute terms should make you extremely cautious and are usually incorrect as most of the arguments tend to not go to extremes. These options are classic traps in inference questions.

Hi Prateek,

Let me see if I can help.

The issue with your answer C, is that no where in the passage does it suggest that there are other fish that are not sharks with a cartilaginous skeleton. In fact it says the opposite - the problem scientists are having is that they've not come across such a thing in an eel like fish before.

D is correct, because you can infer that because many scientists are happy to call this fish an eel, that eel's must be found close to Papa New Guinea.

Does that make sense?

James

I can as well say, B is correct, because you can infer that because many scientists are happy to use only the physical characteristics in classifying the new finding.
And I would be validly as right as the GMATpill guy was... yeah afterall i copied his logic.
Don't create more puzzle than the question already did.

Then another guy said B. Physical characteristics, such as skeletons, are scientists' primary means of classifying new species. - Not stated - Wrong Was D stated?

I want to listen to real guys not outdated members.

It didnt help.
I know why A through E are not the answer.
This is Inference.
I'm commenting cos I saw Kaplan in the source tag. If I had seen "Others", I wouldn't look at this question twice. You know what I mean.

For D to be answer ... and i think it can be inferred from the following statement in the passage.
A new species of fish has just been discovered living in great numbers in the waters off Papua New Guinea. The fish exhibits some characteristics belonging to sharks, such as a cartilaginous skeleton. However, the fish also exhibits characteristics belonging to eels, such as a long, snake-like body. Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel. But the cartilaginous skeleton puzzles them, since no known eel possesses one. So scientists are still unsure as to the fish's precise classification, but they agreed immediately that the most logical classification would be as either a shark or an eel.

hence we can infer that the region is eel friendly ..HOW??? The scientists hypothesis that since this eel like looking fish is found in eel populated area ,it has to be an eel species ..
BTW I too choose a different answer(B) and then I read the passage closely and deduced this...
I may be wrong...
Damm these inference questions....

Hi,

Sorry, did not see your earlier post of 12 april...
Nikhil is bang on with his explanation..

Rather even the first time you read it, you should be slightly wary of --
Because of the habitat where it was found and its obviously eel-like body, almost all scientists believe that the fish is an eel..
We are talking of characteristics and then all of a sudden the words " Because of the habitat where it was found" are spoken, which do not have otherwise any place in the argument..

And as it turns out, the Q asks for some inference and this HABITAT comes up once again..

And, Ofcourse, the argument says that one of the reasons the new species should be classified as EEL is because of its habitat... so the place must be home to EELs..

Hello Everyone,

Is not E a possible attack on the conclusion?

If yes, then is it not the right answer?

If the author of the question intended the "either....or" construction to mean both, then I think this is a poorly worded question, and I'd be interested in the source. Couple sources for why I think "either....or" is used incorrectly in this context.

https://www.merriam-webster.com/dictionary/either%20or - Merriam Webster defines "either or" as an unavoidable choice or an exclusive division between only two alternatives. This pretty clearly indicates that "either or" is not intended to mean both. "Either" as a standalone, without the or, can be used to mean both, but "either...or" can't.

An additional piece of evidence is "either...or" as used in legal documents. http://www.adamsdrafting.com/a-dispute- ... either-or/ - discussion over the use of "either...or" in a legal context with the takeaway being that it can be ambiguous and needs to be better defined, though the use of both "either" and "or" together more strongly suggests exclusivity, as opposed to inclusiveness.

Further, if someone interpreted "either...or" to mean an exclusive choice between one of two options, which is a very reasonable interpretation, then answer "E" would be the most strongly supported answer within the choices. Answer "D" would be more ambiguous as the reader would have to assume that the wording "Because of the habitat where it was found" to imply that it was hospitable for eels. A equally legitimate interpretation of "the habitat where it was found" could mean that the habitat was hostile for sharks, so unlikely that sharks would be there, hence by deduction, the scientists concluded the fish was most likely an eel.

Thoughts?

So what is the OA? I believe A also makes sense since to be classified as either shark or eel, it should cover all the characteristics!

Hi Habdo,

The OA is (D) because it is the only 100% provable statement made.
