The question is compare and contrast the architectural details of the Early Christian basilica with those of the Gothic Cathedral.

My question is, what is this question exactly asking? Are they asking to compare the basilica with a Cathedral, or are they asking to compare the Christian basilica with the Cathedral basilica.
And is a basilica a Church ?

Basilica is the term for the earliest of Christian church buildings, yes. You should easily be able to see the differences.

The question is asking you to compare and contrast the architectural details of the Early Christian basilica with those of the Gothic Cathedral. In other words, it wants you to discuss the similarities and differences in the architectural style and features of these two types of buildings.

To clarify, they are indeed asking you to compare a Christian basilica (specifically, the Early Christian basilica) with a Gothic Cathedral. Both structures are types of religious buildings, but they differ in architectural style and design.

A basilica is a type of building that has been historically used for various purposes, including secular and religious gatherings. However, in the context of this question, it refers to a Christian basilica, which is a specific architectural style commonly used for early Christian churches. Basils are characterized by a rectangular plan, an entrance façade with columns or arcades, and a prominent central nave with side aisles.

On the other hand, a Cathedral is a specific type of Christian church which serves as the principal church within a diocese, typically housing the bishop's seat. There are various architectural styles of cathedrals, and in this question, you are being asked to compare the Gothic Cathedral with the Early Christian basilica.

To answer the question, you will need to conduct research on the architectural features and characteristics of both the Early Christian basilica and the Gothic Cathedral and then compare and contrast them based on those findings.
