    well-preserved complete skeleton of an ancient marine reptile, she
  3. well-preserved, complete skeleton of an ancient marine reptile, which sheCevap
  4. D
    well-preserved, complete skeleton of an ancient marine reptile; which she

Cevap

The correct option is the one that separates the coordinate adjectives with a comma, has no comma before the noun, and uses a comma to introduce the dependent relative clause.
The correct option properly punctuates the sentence by placing a comma between the coordinate adjectives 'well-preserved' and 'complete' to show they independently modify the noun 'skeleton'. It correctly removes the erroneous comma before 'skeleton' and uses a comma to set off the non-essential relative clause starting with 'which'.

Adım Adım Çözüm

1
Analyze the coordinate adjectives modifying the noun 'skeleton'.
The adjectives 'well-preserved' and 'complete' are coordinate because they can be reversed ('complete, well-preserved skeleton') and can be joined by 'and' ('well-preserved and complete skeleton'). Therefore, they must be separated by a comma, but no comma should be placed between the final adjective 'complete' and the noun 'skeleton'.
To ensure proper punctuation rules for coordinate adjectives are applied.
2
Determine the relationship between the main clause and the relative clause.
The clause beginning with 'which' is a non-essential relative clause that adds descriptive info about the skeleton. It must be separated from the main clause by a comma, not a semicolon or no punctuation.
To determine the correct punctuation at the clause boundary.
3
Evaluate the choices to find the one that meets all grammatical requirements.
The choice containing 'well-preserved, complete skeleton... which she' is the only option that correctly applies both coordinate adjective punctuation and non-essential clause punctuation without introducing comma splices or fragments.
To select the grammatically correct option.
