The following passage contains an underlined portion. Choose the option that best replaces this portion to ensure the sentence is grammatically correct.

Discovered in 1977, deep-sea hydrothermal vents support extraordinary ecosystems that thrive in complete darkness. Because these organisms cannot access sunlight, they must find alternative energy sources; consequently, they rely on chemosynthetic bacteria. These specialized microbes, which live in symbiosis with tube worms, convert toxic chemicals into usable organic <u>matter, they form</u> the foundation of a unique food web.

Which of the following choices best replaces the underlined portion of the passage?

  1. A
    matter, they form
  2. B
    matter; forming
  3. matter, formingCevap
  4. D
    matter, that forms

Cevap

The correct choice is 'matter, forming', which uses a comma and a participial phrase to avoid a comma splice.
The correct option is 'matter, forming'. In the original sentence, the clause before the comma ('These specialized microbes... convert toxic chemicals into usable organic matter') and the clause after the comma ('they form the foundation of a unique food web') are both independent clauses. Separating them with only a comma results in a comma splice. Replacing the second independent clause with a participial phrase starting with the present participle 'forming' eliminates the subject 'they' and subordinates the clause, turning it into a modifying phrase. This resolves the comma splice grammatically and maintains a smooth flow.

Adım Adım Çözüm

1
Identify the clause boundary and structure of the sentence.
The sentence contains two main clauses: 'These specialized microbes... convert toxic chemicals into usable organic matter' and 'they form the foundation of a unique food web'.
Understanding the structure of the clauses helps determine if they are independent or dependent.
2
Determine if the clauses are independent.
Both clauses contain a subject and a verb and can stand alone as complete thoughts, making them independent clauses.
Two independent clauses cannot be joined by a comma alone (comma splice) or separated by a semicolon if one is modified into a fragment.
3
Evaluate the choices to fix the comma splice.
Using the option with 'matter, forming' changes the second clause into a dependent participial phrase modifying the main clause, which correctly resolves the comma splice.
A participial phrase does not require a coordinating conjunction and can be attached to an independent clause with a comma.
