Cevap

decades; in fact, researchers
The correct option correctly uses a semicolon to separate two closely related independent clauses. The transitional phrase 'in fact' is correctly followed by a comma.

Adım Adım Çözüm

1
Analyze the clauses on either side of the underline to determine if they are independent or dependent.
The first clause ('A single whale fall can support a complex ecological community for decades') is independent. The second clause ('in fact, researchers have identified distinct successional stages...') is also independent, containing both a subject ('researchers') and a verb ('have identified') to express a complete thought.
Correct punctuation depends on the structural relationship between the connected clauses.
2
Evaluate how transitional adverbs connect independent clauses.
Transitional adverbs like 'in fact' cannot connect independent clauses with only a comma, as this creates a comma splice. They must be preceded by a semicolon (or period) and followed by a comma.
A semicolon is needed to avoid a comma splice while maintaining the logical flow between the two closely related sentences.
3
Check the other options to ensure no fragments or incorrect dependent clauses are created.
Adding 'since' or 'which' introduces a subordinating element, turning the second clause into a dependent clause. Separating it with a semicolon then results in a fragment error.
Semicolons can only connect two independent clauses; they cannot connect an independent clause to a dependent clause.
