Zorluk: OrtaRun-on Sentences and Comma Splices

The passage below is from an article about biotechnology in prosthetics.

Although synthetic materials are commonly used in modern prosthetic design, researchers are experimenting with mycelium, the root structure of fungi. This organic substance is incredibly durable and lightweight; moreover, because it is fully biodegradable, it offers a sustainable alternative to plastics, it can be easily grown into custom shapes. This development could significantly reduce medical waste in clinics worldwide.

Which of the following alternatives to the underlined portion is grammatically correct?

  1. A
    NO CHANGE
  2. B
    moreover, because it is fully biodegradable. It offers a sustainable alternative to plastics, and it can be easily grown into custom shapes.
  3. moreover, because it is fully biodegradable, it offers a sustainable alternative to plastics; it can be easily grown into custom shapes.Cevap
  4. D
    moreover, because it is fully biodegradable; it offers a sustainable alternative to plastics, it can be easily grown into custom shapes.

Cevap

The grammatically correct revision is the option that uses a semicolon to separate the two independent clauses ('it offers a sustainable alternative to plastics' and 'it can be easily grown into custom shapes') while keeping the introductory dependent clause ('because it is fully biodegradable') properly attached with a comma.
The correct option resolves the comma splice by using a semicolon to separate the two independent clauses ('it offers a sustainable alternative to plastics' and 'it can be easily grown into custom shapes'). Semicolons are grammatically appropriate for connecting closely related independent clauses without coordinating conjunctions.

Adım Adım Çözüm

1
Identify the clause boundaries in the underlined portion of the sentence.
The underlined text contains a dependent clause ('because it is fully biodegradable') and two independent clauses ('it offers a sustainable alternative to plastics' and 'it can be easily grown into custom shapes').
Understanding the structure of the sentence is necessary to identify the punctuation errors present.
2
Diagnose the error in the original sentence.
The two independent clauses are joined only by a comma (', it can be easily grown...'), which is a comma splice error.
Identifying the error helps eliminate options that do not correct it or that introduce new grammatical errors.
3
Evaluate the choices to find the correct punctuation that resolves the comma splice without creating new errors.
Using a semicolon after 'plastics' correctly separates the two independent clauses. Separating the dependent clause with a semicolon is incorrect (semicolon fragment), as is separating the dependent clause with a period (sentence fragment).
A semicolon is the standard way to connect two independent clauses when no coordinating conjunction is used, and a comma must separate the introductory dependent clause from its main clause.
