(A) This option focuses on surrounding buildings, which are not discussed in the argument. Since the claim specifically pertains to the streets, the state of nearby buildings is irrelevant.

(B) The argument does not depend on whether other areas in Castellonia also preserve medieval street layouts. Even if such areas exist, it does not undermine the claim that the old quarter streets provide an authentic representation.

(C) While this might be true, it does not pertain to the argument's claim that Castellonia’s streets authentically represent medieval street design due to minimal modern intervention. The argument does not involve comparisons with modern designs.

(D) This is a key assumption supporting the argument. For Castellonia’s streets to authentically represent medieval design, they must retain their original medieval characteristics more closely than other historic city centers that have been modernized or rebuilt.

(E) This focuses on the preservation methods rather than the result—authentic medieval representation. The argument is concerned with the streets’ resemblance to their original design, not how this was achieved.

Ans-(D) is the most appropriate.

Which of the following assumptions is the argument above making?

(A) The buildings surrounding the old quarter of Castellonia are largely from the same era as the cobblestone streets.
(B) There are no other city areas in Castellonia that have preserved their medieval street layouts.
(C) Many modern urban centers have street designs based on principles developed in medieval times.
(D) The cobblestone streets in Castellonia’s old quarter are more similar to their original medieval design than those in most other historic city centers.
(E) The techniques used to preserve streets in Castellonia have not changed significantly over the centuries.

Answer D fits best since addresses the uniqueness of the city center discussed in the question. Rest of the answers are out of scope or might be inferred in the real world but not in the gmat, what we only know is that it had minimal modern intervention, unlike others. Select D

The cobblestone streets in the old quarter of Castellonia provide urban planners and historians with an authentic representation of medieval street design.

These streets have been preserved with minimal modern intervention, unlike many other historic city centers that have been updated or rebuilt.

Which of the following assumptions is the argument above making?

(A) The buildings surrounding the old quarter of Castellonia are largely from the same era as the cobblestone streets.
The argument is not concerned with the buildings surrounding the old quarter of Castellonia but is concerned with he cobblestone streets in the old quarter of Castellonia only. Therefore, assumption can not be about surrounding buildings.
Incorrect

(B) There are no other city areas in Castellonia that have preserved their medieval street layouts.
This is a superlative statement. There may be other city areas in Castellonia that have preserved their medieval street layouts but the argument is concerned with the cobblestone streets in the old quarter of Castellonia.
Incorrect

(C) Many modern urban centers have street designs based on principles developed in medieval times.
The argument is concerned with authentic representation of medieval street design preserved with minimal modern intervention and is not concerned with modern urban centers have street designs based on principles developed in medieval times.
Incorrect

(D) The cobblestone streets in Castellonia’s old quarter are more similar to their original medieval design than those in most other historic city centers.
If the cobblestone streets in Castellonia’s old quarter are NOT more similar to their original medieval design than those in most other historic city centers, then the cobblestone streets in the old quarter of Castellonia DOES NOT provide urban planners and historians with an authentic representation of medieval street design.
If assumption is negated, the conclusion falls apart.
Correct

(E) The techniques used to preserve streets in Castellonia have not changed significantly over the centuries.
The argument / conclusion is not about the techniques used to preserve streets in Castellonia. The techniques used to preserve streets in Castellonia may or may not have changed significantly over the centuries but these streets have been preserved with minimal modern intervention.
Incorrect

IMO D

Correct Answer:
(D) The cobblestone streets in Castellonia’s old quarter are more similar to their original medieval design than those in most other historic city centers.


Why the other options are incorrect:
(A) This is not assumed in the argument. It only discusses the streets, not the buildings around them.
(B) The argument does not assume there are no other preserved medieval street layouts in Castellonia, just that Castellonia’s streets are more authentic than most other city centers.
(C) The argument doesn’t address modern street designs or their origins in medieval principles. It focuses on preserving medieval authenticity.
(E) The argument doesn’t discuss the techniques used in preservation, only the result of minimal modern intervention.

(A) This option talks about the buildings surrounding the streets, which is not the focus of the argument. The preservation of the streets is the main point, not the surrounding buildings.
(B) The argument doesn't claim there are no other areas with preserved medieval streets in Castellonia; it only emphasizes that Castellonia’s streets have been preserved more authentically than in other cities.
(C) The argument doesn’t mention modern street design or its relation to medieval principles, making this assumption irrelevant to the main point.
(D) The cobblestone streets in Castellonia’s old quarter are more similar to their original medieval design than those in most other historic city centers.
(E) The argument does not address how the streets were preserved or whether techniques have changed; it only emphasizes the outcome of minimal modern intervention.

Negating the options to know the assumption -

(A) The buildings surrounding the old quarter of Castellonia ARE NOT largely from the same era as the cobblestone streets - this doesn’t weaken the conclusion as it’s talking about surrounding buildings - ELIMINATE
(B) There are other city areas in Castellonia that have preserved their medieval street layouts - Doesn’t weaken the conclusion - ELIMINATE
(C) Many modern urban centers DO NOT
HAVE street designs based on principles developed in medieval times - Strengthens the conclusion - ELIMINATE
(D) The cobblestone streets in Castellonia’s old quarter are LESS similar to their original medieval design than those in most other historic city centers - Weakens the conclusion as it tells there are other places which are more authentic than the said place- CORRECT
(E) The techniques used to preserve streets in Castellonia HAVE CHANGED significantly over the centuries - Doesn’t help with the conclusion - ELIMINATE

IMO D

(A) The buildings' era is irrelevant because the argument focuses on the streets, not the surrounding structures.
(B) Whether other areas in Castellonia have preserved medieval streets is unrelated to the claim about the old quarter specifically.
(C) The influence of medieval street design on modern cities is not relevant to Castellonia's streets' authenticity.
(D) Correct. The argument assumes Castellonia's streets are less altered than other historic city centers, making them more authentic.
(E) The preservation techniques used are not critical; what matters is that the streets have minimal modern intervention.

To identify the assumption of the argument, we need to find a statement that must be true for the argument to hold. The argument is:
• The cobblestone streets in the old quarter of Castellonia provide an authentic representation of medieval street design because they have been preserved with minimal modern intervention.
• This is contrasted with other historic city centers that have been updated or rebuilt.

Analysis of the Answer Choices:

(A) The buildings surrounding the old quarter of Castellonia are largely from the same era as the cobblestone streets.
• The argument is focused on the streets, not the buildings. The authenticity of the streets does not depend on the era of the buildings.
• Incorrect.

(B) There are no other city areas in Castellonia that have preserved their medieval street layouts.
• The argument is about the uniqueness of Castellonia’s old quarter in comparison to “many other historic city centers,” not areas within Castellonia.
• Incorrect.

(C) Many modern urban centers have street designs based on principles developed in medieval times.
• The argument does not rely on this assumption; it compares Castellonia’s streets to other historic centers, not modern urban centers.
• Incorrect.

(D) The cobblestone streets in Castellonia’s old quarter are more similar to their original medieval design than those in most other historic city centers.
• The argument claims Castellonia provides an authentic representation due to minimal modern intervention. For this to be valid, Castellonia’s streets must be closer to their original design than the streets in other historic centers.
• Correct.

(E) The techniques used to preserve streets in Castellonia have not changed significantly over the centuries.
• The argument is about the outcome (authentic representation), not the preservation techniques used.
• Incorrect.

Correct Answer: (D)

(A) The buildings surrounding the old quarter of Castellonia are largely from the same era as the cobblestone streets.
This assumption isn't made in the argument. The argument focuses on the cobblestone streets, not the buildings surrounding them. The buildings could be from a later era, and the argument doesn't assume otherwise.

(B) There are no other city areas in Castellonia that have preserved their medieval street layouts.
The argument doesn't assert or imply that Castellonia has no other preserved areas. It simply compares the old quarter to other historic city centers, implying that the old quarter stands out in its preservation.

(C) Many modern urban centers have street designs based on principles developed in medieval times.
This is not relevant to the argument. The argument is focused on the preservation of streets in Castellonia and how they remain close to their medieval origins. There is no comparison to modern urban centers or their street designs.

(D) The cobblestone streets in Castellonia’s old quarter are more similar to their original medieval design than those in most other historic city centers. CORRECT
The argument contrasts Castellonia's preserved streets with those in other historic city centers that have been updated or rebuilt. The comparison suggests that Castellonia's streets are more authentically preserved, which implies that they are closer to their original medieval design than streets in other cities. This assumption is central to the argument.

(E) The techniques used to preserve streets in Castellonia have not changed significantly over the centuries.
The argument doesn't discuss the preservation techniques or whether they have changed.
