Zorluk: Çok zorSubordination and Coordination

The following passage contains an underlined portion. Choose the option that best corrects the underlined portion to ensure proper subordination and coordination.

Although the geochemist initially hypothesized that the mineral deposits were formed by volcanic <u>activity; but subsequent isotopic analysis of the crystals revealed a freshwater origin, complicating</u> the team's geological timeline.

Which option is the most grammatically correct and effective choice for the underlined portion?

  1. A
    activity; but subsequent isotopic analysis of the crystals revealed a freshwater origin, complicating
  2. B
    activity, subsequent isotopic analysis of the crystals revealed a freshwater origin; complicating
  3. activity, subsequent isotopic analysis of the crystals revealed a freshwater origin, complicatingCevap
  4. D
    activity, subsequent isotopic analysis of the crystals revealed a freshwater origin, this finding complicated

Cevap

activity, subsequent isotopic analysis of the crystals revealed a freshwater origin, complicating
The correct option correctly uses a comma to connect the introductory dependent clause ('Although the geochemist initially hypothesized...') to the main independent clause ('subsequent isotopic analysis of the crystals revealed a freshwater origin'). It also avoids the redundant coordinating conjunction 'but' and correctly sets off the modifying participial phrase ('complicating the team's geological timeline') with a comma rather than a semicolon or comma splice.

Adım Adım Çözüm

1
Analyze the sentence structure and identify the dependent and independent clauses.
The sentence begins with the subordinating conjunction 'Although', which makes 'Although the geochemist initially hypothesized that the mineral deposits were formed by volcanic activity' a dependent clause. This dependent clause must be followed by an independent clause to form a complete sentence.
Identifying clause types is essential for determining appropriate punctuation and conjunctions.
2
Evaluate the punctuation and conjunctions connecting the first two clauses.
A dependent clause cannot be separated from the main clause by a semicolon. Furthermore, the subordinating conjunction 'Although' already establishes the contrast, so using the coordinating conjunction 'but' is redundant.
This eliminates the original phrasing (which uses both a semicolon and 'but') and establishes that a comma must follow 'activity' with no coordinating conjunction.
3
Evaluate the relationship of the final phrase to the rest of the sentence.
The final part of the sentence, 'complicating the team's geological timeline', is a participial phrase. It cannot be separated by a semicolon, as that would create a fragment. Additionally, replacing 'complicating' with 'this finding complicated' creates a new independent clause, which results in an ungrammatical comma splice when joined only by a comma.
This eliminates the options containing the semicolon before 'complicating' and the comma splice ending with 'this finding complicated'.

Anahtar Kavram

Subordination and coordination rules require that dependent clauses be joined to independent clauses using appropriate punctuation (usually commas) rather than semicolons, and without redundant conjunctions. Additionally, independent clauses cannot be spliced together with only a comma, and dependent phrases cannot be isolated by semicolons.
