Zorluk: OrtaRun-on Sentences and Comma Splices

Dendrochronologists studying structural timbers in medieval cathedrals analyze annual growth rings to determine exact felling dates. Variations in ring width reflect past climatic conditions, providing a high-resolution record of local rainfall fluctuations. These precise growth patterns allow researchers to date architectural modifications with remarkable accuracy, however, unseasonal weather anomalies can sometimes complicate the tree-ring alignment. By cross-referencing multiple timber samples from the same region, scholars can nevertheless resolve these discrepancies.

Which choice best resolves the grammatical error in the underlined portion?

  1. A
    NO CHANGE
  2. accuracy; however, unseasonal weather anomalies can sometimes complicateCevap
  3. C
    accuracy; however, because unseasonal weather anomalies can sometimes complicate
  4. D
    accuracy. Because unseasonal weather anomalies can sometimes complicate

Cevap

The option placing a semicolon before 'however' and a comma after it ('accuracy; however, unseasonal weather anomalies can sometimes complicate') is the correct choice.
The option placing a semicolon before 'however' and a comma after it correctly separates two complete independent clauses joined by a conjunctive adverb, resolving the comma splice without creating sentence fragments.

Adım Adım Çözüm

1
Analyze clause structures around the underlined portion
The clause before 'however' ('These precise growth patterns allow researchers to date architectural modifications with remarkable accuracy') and the clause after 'however' ('unseasonal weather anomalies can sometimes complicate the tree-ring alignment') are both complete independent clauses capable of standing alone.
Identifying clause boundaries determines the punctuation required.
2
Evaluate the punctuation needed for a conjunctive adverb
When joining two independent clauses using a conjunctive adverb such as 'however', a semicolon (or period) must precede the adverb, and a comma must follow it.
A comma alone before a conjunctive adverb creates an illegal comma splice between independent clauses.
3
Verify that the chosen option does not introduce fragments or faulty subordination
The option using a semicolon followed by 'however,' correctly connects the two independent thoughts while preserving complete grammatical sentence structure.
Subordinating words like 'because' should not follow a semicolon if they turn the subsequent clause into an incomplete fragment.
