Zorluk: Çok zorSentence-Level Transitions

During the late twentieth century, ecologists noticed that songbird populations in eastern North American forests were declining at an alarming rate. [1] For example, they blamed this decline on local factors like pesticide use, subsequent long-term studies revealed that the primary driver was actually habitat fragmentation in the birds' wintering grounds in Central America.

Which choice best replaces the underlined portion [1] to establish the most logical transition between the sentences?

  1. A
    NO CHANGE
  2. Although they initiallyCevap
  3. C
    Indeed, they
  4. D
    However, they

Cevap

The choice that begins with 'Although they initially' is correct because it resolves the comma splice and establishes the proper logical transition of contrast.
The correct option introduces the subordinating conjunction 'Although,' which turns the first clause ('Although they initially blamed this decline on local factors like pesticide use') into a dependent clause. This dependent clause can then be correctly joined to the subsequent independent clause ('subsequent long-term studies revealed...') by a comma, resolving the comma splice. Pedagogically, this option also correctly captures the logical transition of contrast between the initial, incorrect belief and the actual cause discovered later.

Adım Adım Çözüm

1
Analyze the relationship between the ideas in the passage.
The first sentence introduces the decline of songbirds. The underlined portion begins a clause about initial blame (pesticide use), while the following clause reveals the true cause (habitat fragmentation). This indicates a relationship of contrast between the early hypothesis and the later scientific consensus.
Understanding the logical connection between clauses is necessary to select the correct transition.
2
Examine the grammatical structure of the sentence.
The sentence contains two independent clauses: 'they blamed this decline on local factors...' and 'subsequent long-term studies revealed...'. These are joined by a comma, which creates a comma splice.
Transitions must be grammatically correct and avoid punctuation errors such as comma splices.
3
Evaluate the choices for both logical fit and grammatical correctness.
Using a subordinating conjunction like 'Although' makes the first clause dependent, which resolves the comma splice. It also correctly establishes the contrast relationship.
The correct choice must satisfy both the logical meaning of the passage and the rules of standard English grammar.
