Zorluk: ZorClause Boundaries and Linking

To survive nocturnal hunting in shallow waters, the Hawaiian bobtail squid (*Euprymna scolopes*) hosts bioluminescent bacteria inside a specialized light organ. The squid provides these microbes with nutrients and a secure habitat ________ the bacteria emit light that mimics moonlight, effectively camouflaging the squid from predators below.

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

  1. A
    , in turn,
  2. B
    in turn
  3. ; in turn,Cevap
  4. D
    although, in turn,

Cevap

The correct choice is the option using a semicolon followed by a transition phrase ('; in turn,') to separate the two independent clauses.
The sentence consists of two independent clauses: 'The squid provides these microbes with nutrients and a secure habitat' and 'the bacteria emit light that mimics moonlight...' To link these two independent clauses grammatically, a semicolon is required when no coordinating conjunction is used. The transitional phrase 'in turn' is correctly followed by a comma to establish the relationship between the two clauses.

Adım Adım Çözüm

1
Analyze the structure of the clauses before and after the blank.
The first clause ('The squid provides these microbes with nutrients and a secure habitat') is independent. The second clause ('the bacteria emit light that mimics moonlight...') is also independent.
Identifying clause types determines what punctuation is grammatically required to link them.
2
Evaluate the grammatical rules for linking two independent clauses.
Two independent clauses must be joined by a period, a semicolon, a colon, or a comma paired with a coordinating conjunction (FANBOYS).
Using a comma alone or no punctuation at all results in grammatical errors such as comma splices or run-ons.
3
Test the available options against these rules.
The option with the semicolon ('; in turn,') correctly separates the independent clauses, whereas the comma option creates a comma splice, the option with no punctuation creates a run-on, and the subordinating option creates a sentence fragment.
Selecting the option that correctly adheres to Standard English conventions for clause boundaries.
