The quagga, or Equus quagga, an extinct subspecies of the zebra, is not only one of the most intriguing phenomena in the animal kingdom but also an important milestone in genetic research, specifically DNA research. The front part of the quagga was striped and looked like that of any zebra. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider. The rear part of the quagga was plain brown, devoid of any stripes. Interestingly, Okapi markings are nearly the reverse of the quagga, with the forequarters being mostly plain and the hindquarters being heavily striped although the okapi is a relation of neither the quagga in particular nor the zebra in general—its closest taxonomic relative is the giraffe. The quagga became extinct in the 19th century, possibly as a result of being hunted for its meat, hide, and to preserve feed for domesticated stock. Fortunately, there is a photograph of a living quagga specimen, taken at a London zoo. Still, the quagga’s story did not end with its extinction. The quagga was the first extinct creature to have its DNA studied. Part of this genetic research was conducted at the Smithsonian Institution. DNA from mounted specimens was successfully extracted in 1984, but the technology to use recovered DNA for breeding does not yet exist. Hope may arise from the Quagga Project in South Africa, which attempts to recreate the quagga by selective breeding from plains zebra stock, a related zebra subspecies.

1. Which of the following could be inferred from the passage about the Okapi?

(A) taxonomic examination reveals the genetic resemblance between the Okapi and the quagga.
(B) On a superficial examination, the Okapi appears to be related to the zebra.
(C) On a superficial examination, the Okapi appears to be related to the giraffe.
(D) The Okapi's stripes are a result of genetic traits shared with the giraffe.
(E) The Okapi's stripes are a result of genetic traits shared with the zebra.

2. The quagga is regarded by the author with?

(A) interest
(B) ridicule
(C) criticism
(D) appreciation
(E) fascination

Answer Choice A. If you chose E: There is no need to consult the passage in order to see that this answer choice is incorrect. The word fascination automatically eliminates it as it is too strong. On the GMAT, a scientist may be interested in or intrigued by something. Fascination is over the top. Same for AC B.

Thanks for the response Abhishek. However, i would want to understand more from you on answer to question 1.

Between choices C and B, I see a condtradiction in your explanation. You rejected option C because of term 'Superficial'; however, the term is used in B as well.
Also, author rejects okapi's relation to Zebra, then how can we select B as answer.

Thanks

I am goin to explain this a bit further....

Superficial , as used in the passage refers to a casual , consider the following lines -

The front part of the quagga was striped and looked like that of any zebra. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider. The rear part of the quagga was plain brown, devoid of any stripes. Interestingly, Okapi markings are nearly the reverse of the quagga, with the forequarters being mostly plain and the hindquarters being heavily striped although the okapi is a relation of neither the quagga in particular nor the zebra in general - its closest taxonomic relative is the giraffe.

The front part of the quagga was striped and looked like that of any zebra. In the mid-section, the stripes faded and the dark, inter-stripe spaces became wider. The rear part of the quagga was plain brown, devoid of any stripes. - States that the quagga , striped and looked like zebra.

Okapi markings are nearly the reverse of the quagga, with the forequarters being mostly plain and the hindquarters being heavily striped - States that marking of Okapi was reverse of the markings of the quagga.

We can clearly draw a relation that the Okapi and quagga are related to the Zebra ( Superficially - Without any scientific evidence in support of the same)

Now comes the twist -

the okapi is a relation of neither the quagga in particular nor the zebra in general - its closest taxonomic relative is the giraffe. - The author mentions Taxonomy in support of scientific basis for the claim.

Now lets come to your query ,

B. On a superficial examination, the Okapi appears to be related to the zebra. - True , both Okapi and quagga superficially seems related to the zebra.
C. On a superficial examination, the Okapi appears to be related to the giraffe. - Not true , the Okapi and quagga supeerficially seems related to the zebra .

I can see th official answer is revealed, but can't find it. May be because I am new to forums. Can someone please help?!

In the meantime for now can somone please review my answers and let me know if they are true?

Which of the following could be inferred from the passage about the Okapi?

A. taxonomic examination reveals the genetic resemblance between the Okapi and the quagga. - Not true

(i) Opening line says - " The quagga, or Equus quagga, an extinct subspecies of the zebra ".
(ii) Further the author states - " although the okapi is a relation of neither the quagga in particular nor the zebra in general - its closest taxonomic relative is the giraffe.

B. On a superficial examination, the Okapi appears to be related to the zebra.

While describing the Okapi the author states - " ..... lthough the okapi is a relation of neither the quagga in particular nor the zebra in general.... "
Thus superficially (Based on common characteristics of Stripes) it appears that the Okapi is related to the Zebra.

C. On a superficial examination, the Okapi appears to be related to the giraffe.

The author states - " although the okapi is a relation of neither the quagga in particular nor the zebra in general - its closest taxonomic relative is the giraffe."

This is a claim made by the author based on scientific evidence , hence it is not superficial examination.

D. The Okapi's stripes are a result of genetic traits shared with the giraffe. - Nothing stated in the passage.
E. The Okapi's stripes are a result of genetic traits shared with the zebra. - Nothing stated in the passage.

Superficial mean = On relative judgement (Without any serious scientific evidence )

The quagga is regarded by the author with?

The author states - " The quagga, or Equus quagga,......., is not only one of the most intriguing phenomena in the animal kingdom but also an important milestone in genetic research...... "

A. interest - True
B. ridicule - Absolutely not , there is no element of ridicule.
C. criticism - The author doesn't criticise anyone.
D. appreciation - Not true , there is none to appreciare.
E. fascination- Could have been true , if the last 3 lines doesn't seem to fascinate the author.

Hi ,

For question two I market option E (Fascination). Can you please elaborate why option A (interest) is selected.
How to differentiate between these two options because almost similar.

Hi anc, Welcome to the GMAT Club!

The option E is discarded on account of being too extreme. Fascination is extreme vs. interest as the author describes the animal as "the most intriguing phenomenon in the animal kingdom and also of importance from a DNA study point of view". In light of the two ways ( at the start of the passage) used by the author, the author reveals an interest in the animal and not "fascination".

Moreover, whenever you encounter extreme words - you can almost always discard the option unless the author explicitly uses the exact verbiage in the passage or the word is an exact translation of another extreme word used in the passage.

Does this all make sense?

Best,
