Thank you so much ReedArnoldMPREP - your followup really helped.

ReedArnoldMPREP
In the end, I don't know if it really even matters that much whether it's just these motifs were whether it's all motifs that have been found in other cities. The 'jump' to the conclusion is the same: "Oh, well, if the same motifs have been found in other cities, probably some traveling artists made them all."

The question I'm wondering is: Maybe these mosaics weren't made by traveling artisans EVEN THOUGH the same motifs (be it some motifs or all motifs, I'm not too worried about it) appeared in many other cities?


If I understand, what you mean by the red and the purple above - it is this.

Even if (C) was not over-kill, but instead (C) was more targeted -- (C) would be still wrong.

What I mean by "Targeted" is the following :

Quote:
(C-variant 1)
ALL hare motifs , ALL patridge motifs , ALL Mediterranean fish motifs – seen in Sepphoris mosaics -- are seen in mosaics in other part of the Roman Empire.

or

(C-variant 2)
AT-LEAST ONE hare motif , AT-LEAST ONE patridge motif, AT-LEAST ONE Mediterranean fish motif – seen in Sepphoris mosaics -- is seen in mosaics in other part of the Roman Empire.

You are saying (c-variant 1) and (c-variant 2) would still be wrong ?

(c-variant 1) and (c-variant 2) would not really be assumptions

(c-variant 1) and (c-variant 2) would be more likely -- inferences, but not assumptions

Is that what you are saying, when you mention the red and the purple.

I'm sorry I'm a little confused by the question, but I'll do my best.

C variant 1 is what C basically says. "Every motif in Seph. mosaics appears in some other place's mosaic."

C variant 2 is something like an inference, yes. But it's not necessary (nor sufficient) for the CONCLUSION of the argument. We already know that it is true by this: "Since identical motifs appear in mosaics found in other Roman cities"

The question in either C-variant remains: does this REALLY MEAN a traveling artist came to Seph to paint the mosaics, or might something else have happened?

Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species : a hare, a partridge, and various Mediterranean fish. Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created. Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.

Which of the following is an assumption on which the argument depends?


(A) The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.

(B) There is no single region to which all the species depicted in the Sepphoris mosaics are native.

(C) No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.

(D) All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.

(E) There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.


Source : GMATPrep Default Exam Pack
Premises:
Sepphoris had mosaics depicting several animals.
Most of these animals did not live in the Sepphoris region when these mosaics were created.
Identical motifs appear in mosaics found in other Roman cities.

Conclusion: The mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.

The conclusion says that artisans in S did not create these mosaics. That travelling artisans created them because they were found in many cities of Roman Empire. So a bunch of artisans kept going from one city to another creating these mosaics everywhere. What is an assumption here? That say there wasn't a book which was used by various artisans to create mosaics in their own cities. If there was a reference book and everybody used that then we don't need the people to be the same. S's artisans could have created the mosaics in S by referring to that book. Another city P's artisans could have created those same mosaics in P. Then we don't need to have travelling artisans. This is what option (E) says.

(E) There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.

It negates a different explanation (a common repertory) for the premises and hence is needed for our conclusion to hold.


(A) The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area.

All that the conclusion says is that artisans were from outside. It says nothing about the source of the stone.

(B) There is no single region to which all the species depicted in the Sepphoris mosaics are native.

We don't need this to be true for our conclusion. Whether the travelling artisans saw these species in one place or different, doesn't matter.

(C) No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.

Not necessary. The premise says " most of the species represented did not live in the Sepphoris region."
It is possible that some motifs in S's mosaics were only present in S - say the travelling artisans created these only in S. The entire argument talks about 'most of the species not present in S' and that these motifs were present in other cities too. It is not necessary that S could have no unique motif.

(D) All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.

The argument talks about "most of the species..." We cannot apply any rule to "all the animal figures."

Understanding the argument -
The conclusion is that the mosaics were created by traveling artisans. Because
1. Identical motifs appear in mosaics found in other Roman cities.
2. Most of the species represented did not live in the Sepphoris region when these mosaics were created

Let me give you another argument to explain the argument. Sorry, I am passionate about automotive, so allow me to use an example from the auto world. :)

An analysis of car advertisements in a remote mountain village reveals that many promotional materials feature sleek sports cars like Lamborghini and Ferraris. However, these luxury cars are rarely seen in the village, as it's not a typical location for such vehicles. However, since similar car advertisements with high-end models appear in magazines from various regions, it's reasonable to say that advertising agencies from other areas crafted these campaigns.

What if all marketing experts, including the marketing experts of this village, went to Ferrari and Lamborgini launches, and the Ferrari and Lamborgini marketing team gave them ready-to-use designs to start marketing in their areas? In that case, we can't say that advertising agencies from other areas crafted these campaigns.

Now, back to our argument, this is what option E highlights: there was a shared repository that everyone used. So, the artisans native to Sepphoris could very well create them, and we don't need TRAVELLING artisans.

Option Elimination -

(A) The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area. - In our argument, if we say the promotional materials are made of plastic, paper, or cloth, does it even matter? No. Out of scope.

(B) There is no single region to which all the species depicted in the Sepphoris mosaics are native. - Even if there is a single region, as in our example, say Ferrari is headquartered in Maranello, Italy, while Lamborghini is headquartered in Sant'Agata Bolognese, Italy. Does it even matter to our argument, which is "advertising agencies from other areas crafted these campaigns"? No. Out of scope.

(C) No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city. - We should know how to negate it. Wear your sentence correction hat. The key part is "No motifs appear in the Sepphoris mosaics." The rest is a relative clause introduced by that. So, the negation is "some motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city. It means some motifs were unique to Sepphoris. Convert it into our example - some promotional materials were only made for this remote mountainous village. It's possible we can't use the same marketing campaign for a village and city, and on top of this, it is remote and mountainous, so we created something unique for this village. But is it relevant to the argument that "advertising agencies from other areas crafted these campaigns"? No. Out of scope.

(D) All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species. This is equally applicable to natives and travelers. Moreover, the argument already says, "identical motifs appear in mosaics found in other Roman cities." This is not saying anything we don't know. It's a bit worse; it makes it general. Distortion.

(E) There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar. ok.

P : S MOSAIC CONTAINING NON NATIVE SPECIES IS SIMILAR TO OTHER CITY MOSAIC
C: TRAVELLERS FROM ROMAN EMPIRE CREATED THEM
ASSUMPTION: S ARTISTS NEITHER TRAVELS NOR THEY ARE AWARE OF ART OUTSIDE SEPPHORIS. (E EXACT MATCH )

Which of the following is an assumption on which the argument depends?


(A) The Sepphoris mosaics are not composed exclusively of types of stones found naturally in the Sepphoris area. NEGATION :MOSAIC CONTAINS OTHER PART STONES .NEGATION IS SUPPORTING THE CONCLUSION .OUT

(B) There is no single region to which all the species depicted in the Sepphoris mosaics are native.NEGATION: THERE IS A REGION WHERE ALL THE SPECIES ARE NATIVE , SUPPORTS CONCLUSION . OUT

(C) No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.NEGATION :THERE IS SOME MOTIFS EXCLUSIVE TO SEPPHORIS . WEAK WEAKENER OF CONCLUSION

(D) All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.NEGATION: SOME FIGURES IN S MOSAICS ARE UNIDENTIFIABLE : IS IRRELEVANT AS THIS IS A STUDY DRAWBACK .

(E) There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.NEGATION: THERE IS A COMMON REPERTORY OF MOTIFS FAMILIAR TO ARTISTS IN VARIOUS PARTSOF RE INCLUIDING SEPPHORIS AS WELL .

a - Even if stones are exclusive to Sepp, travelers could still create mosaics at Sepp. Doesn’t break argument.
b - Even if all animals came from one region, doesn't affect who created mosaics.Animal origin irrelevant to who made mosaics.

your thought process of c : If negated (motifs unique to Sepp), weakens because travelers unlikely to create something unique just for Sepp.
c - Even if motifs are unique to Sepphoris, traveling artisans could still have created them specifically for Sepphoris—doesn't disprove traveling artisans. Not required.
d - Recognizability of animals already given; irrelevant.

your thought process of e: If common repertory existed, it bolsters the claim."

e - Actually, if common repertory existed, local artists could copy designs without traveling artisans, weakening (not bolstering) the claim. Thus, the author must assume no common repertory existed.

Conclusion: Author wants to prove that mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire. Mosaics of Sepphoris not created by natives.

Premise 1: Excavation gave mosaics depicting animal species
Premise 2: animal species depicted did not live in Sepphoris

Excavation of mosaics with depiction of animals which did not live in the city when created.

Prethinking : Natives did not have the means to depict animals not available in their region

Answer : (E) There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar. - Hence the natives of Sepphoris could not have referred to any repository to create the depictions of animals , and the source of such designs is only from artisans not native to Sepphoris i.e, Travelling artisans

I think one thing that I also missed when I attempted this the first time was the fact that the 2 other ans choices which can break the argument are premises if you look carefully.


"Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species"

(D) All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.

"Since identical motifs appear in mosaics found in other Roman cities"

(C) No motifs appear in the Sepphoris mosaics that do not also appear in the mosaics of some other Roman city.


Other 2 options are definitely not the answer in the first read leaving with E).


And if you really think about E) once you have crossed out the others, answer is in front of you. If everyone or atleast some (which could be relevant for Sepphoris) in Roman Empire were making the mosaics from the same pool of the drawings then the argument breaks.


Hence,
(E) There was not a common repertory of mosaic designs with which artisans who lived in various parts of the Roman Empire were familiar.

Negation of this destroys the argument? Really?
Let's say there was a common repo. Does that mean that travelling artists could not have made the mosaics? How do we know that these elements such as hare etc that are mentioned are contained in the common repo? And even if they are, I can't rule out that the travelling artists didn't make it. Sure, it gives us a case for why it might happen that the local artisans made it but does it destroy the argument? I'm not so sure

(D) All of the animal figures in the Sepphoris mosaics are readily identifiable as representations of known species.

i marked this one on the following basis. Please correct my reasoning


D says that are the animal figure are identifiable animal repr... which can be true bcz what if there were 100 figures and only 10 of them are identified as animal species so we dont know about the rest 90 figures so we cant claim whether someone else made it or not may be other 90 found out to be made my residents then it will be proved that it is not done by people from roman empire rather by the locals. so till we are not sure about all the figures that has been found we can't say who made them. So this indeed breaks the argument then why not it is the answer? It is the most basic thing that the author needs to assume before saying Roman made them bcz they are not found nearby

The conclusion is that the mosaics of Sepphoris were very likely created by traveling artisans. That's much different than concluding that the mosaics were possibly created by traveling artisans.

If (E) is true, then the mosaics could have been created by artisans living anywhere in the Roman Empire. Maybe they were from Sepphoris or maybe they were traveling artisans. So is it still possible that the mosaics were created by traveling artisans? Absolutely, but there is no longer any reason to believe that it was traveling artisans, since the local artisans could have easily made the mosaics themselves.

So, if (E) is true, we can no longer conclude that the mosaics were "very likely" created by traveling artisans. (E) "destroys" the argument regardless of who actually created the mosaics.

But even if only, say, 10% of the figures were hares, partridges, and Mediterranean fish, we'd still be left wondering why those species were depicted at all, given that they did not live in the Sepphoris region. So there would still be evidence suggesting that the mosaics were made by traveling artisans.

Also, we're looking for an assumption on which the argument depends. Imagine that MOST (but not ALL) of the figures were hares, partridges, and Mediterranean fish. Even though that goes against choice (D), it's still strong evidence that the mosaics were made by traveling artisans.

In other words, the argument still works even if SOME of the figures were NOT readily identifiable as representations of known species. So we don't NEED to assume (D) in order for the argument to work.
