Constructed with the finest Italian marble, the floor of the church is its greatest attraction and is more attractive to tourists than are its ornate stained-glass windows.
(A) attraction and is more attractive to tourists than are its ornate stained-glass windows
(B) attraction, itself more attractive to tourists than are its ornate stained-glass windows
(C) attraction, itself more attractive to tourists as are its ornate stained-glass windows
(D) attraction, being more attractive to tourists than its ornate stained-glass windows are
(E) attraction as it more is attractive to tourists than are the church's stained- glass windows
IMO it must be B.
See there are two main attractions in Church:
1)its floor
2)its windows
but floor is more attractive to tourists than windows are.
(A) attraction and is more attractive to tourists than are its ornate stained-glass windows
A is proper in meaning but its not proper construction.
See we say :
Burj Khalifa is tallest building in the world,taller than any other building.
if our intention is to focus on tallness of Burj khalifa we use above sentence.
We wont say
Burj Khalifa is tallest building in the world and it is taller than any other building.
"and " makes these two unrelated clauses having no relation.
Its like citing two features of building without emphasizing any of the features.
(B) attraction, itself more attractive to tourists than are its ornate stained-glass windows
here itself refers to floor ,cant refer to church as church cannot be more attractive than windows.we are comparing two characteristics/two features of church.
Itself here emphasizes that floor is itself more attractive than windows are.
(C) attraction, itself more attractive to tourists as are its ornate stained-glass windows
Correct idiom is More ..Than not More ...as
Also wrong meaning.
it means both floor and windows are equally attractive.
(D) attraction, being more attractive to tourists than its ornate stained-glass windows are
being here is modifying floor (contextually) but being can never be a modifier.So wrong.
(E) attraction as it more is attractive to tourists than are the church's stained- glass windows
wrong meaning
It is like saying
floor is greatest attraction because it more is attractive to tourists than are the church's stained- glass windows.
We are not giving reason for church having greatest attraction ,we are concerned with emphasizing that church's floor has greatest attraction.
Pizza is the most consumed food because it is eaten more than burger.
Does not make sense.So B is the answer.
I don't agree with your reasoning for elimination of A.
Below sentence may sound awkward but I don't find any reasonable flaw. We can avoid using the pronoun "it" to make it sound better.
"Burj Khalifa is tallest building in the world, itself taller than any other building."
If we go by meaning, none of the options sound good. It is already mentioned that the floor is the
attractive than windows.
Only Vanam ranked no. 1 & Vanam ranked higher than AKY.
Second clause is redundant.
I have issues with two pronouns referring to different antecedents - one to the floor & other one to the church.
