Zorluk: ZorClause Boundaries and Linking

Deep-sea hydrothermal vents support highly complex and productive biological communities in the complete absence of solar energy. In these aphotic marine environments, chemosynthetic bacteria form the foundation of the local trophic structure ________ they oxidize dissolved hydrogen sulfide to synthesize organic compounds, thereby providing essential nutrients for specialized species like giant tubeworms.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. ; theyCevap
  2. B
    , they
  3. C
    they
  4. D
    although they

Cevap

The option containing '; they' is correct because it properly connects the two independent clauses using a semicolon.
The correct option correctly uses a semicolon to link two independent clauses: the first describes chemosynthetic bacteria forming the foundation of the trophic structure, and the second explains how they do so by oxidizing hydrogen sulfide.

Adım Adım Çözüm

1
Identify the clauses surrounding the blank.
The first clause is 'In these aphotic marine environments, chemosynthetic bacteria form the foundation of the local trophic structure' (independent). The second clause is 'they oxidize dissolved hydrogen sulfide to synthesize organic compounds...' (independent).
Determining whether the clauses are independent or dependent is necessary to apply the correct punctuation rules.
2
Determine the appropriate punctuation or conjunction to link two independent clauses.
Two independent clauses must be joined by a period, a semicolon, or a comma coupled with a coordinating conjunction (FANBOYS).
Connecting two independent clauses with only a comma or with no punctuation leads to grammatical errors like comma splices and run-ons.
3
Evaluate the choices based on grammatical correctness and semantic relationship.
The semicolon successfully links the two clauses. A comma alone creates a comma splice, omitting punctuation creates a run-on, and using a contrast subordinator introduces an illogical relationship.
Choosing the grammatically correct option that preserves the logical connection between the clauses ensures sentence flow and standard English conventions.
