Cevap

The option containing 'pigeons, but the noise' is correct because it uses a comma and the coordinating conjunction 'but' to link the two contrasting independent clauses.

Adım Adım Çözüm

1
Identify the clause structure of the sentence.
The sentence is composed of two independent clauses: 'They meticulously cleaned the equipment and even removed nesting pigeons' and 'the noise remained'.
Knowing whether the clauses are independent or dependent determines the appropriate punctuation and conjunctions needed to connect them.
2
Analyze the logical relationship between the two clauses.
The clauses express a relationship of contrast: despite cleaning the equipment, the hiss persisted.
The selected conjunction must logically represent this relationship of contrast.
3
Evaluate the grammatical correctness of the options.
A comma combined with the coordinating conjunction 'but' correctly and grammatically joins two independent clauses expressing contrast.
This avoids sentence fragments, comma splices, or illogical transitions.
