Zorluk: OrtaColons, Semicolons, and Dashes

The following passage is adapted from an essay about earth science. Read the passage and determine which punctuation mark best completes the sentence to conform to the conventions of Standard English. Write the correct punctuation mark in the blank.

Cevap:In 1912, German geophysicist Alfred Wegener proposed the theory of continental drift, suggesting that all landmasses were once joined in a supercontinent called Pangaea【;】many of his contemporaries, however, rejected this hypothesis because Wegener could not explain the physical mechanism that drove the movement of the continents.

Cevap

A semicolon (;)
A semicolon is the correct punctuation mark because it properly joins two independent clauses without a coordinating conjunction. In this sentence, the transition word 'however' is functioning parenthetically within the second clause and does not act as a coordinating conjunction.

Adım Adım Çözüm

1
Identify the structure of the clauses before and after the blank space.
The clause before the blank ('In 1912... called Pangaea') and the clause after the blank ('many of his contemporaries... of the continents') are both independent clauses.
Determining clause boundaries helps identify what kind of punctuation is grammatically required to link the parts of the sentence.
2
Analyze the logical relationship between the two independent clauses to choose the correct punctuation mark.
The two independent clauses are closely related but present contrasting ideas (signaled by 'however'), and they are not joined by a coordinating conjunction.
Two independent clauses not joined by a coordinating conjunction must be linked by a semicolon or a colon, depending on their logical relationship.
3
Select the correct punctuation mark based on grammar conventions.
A semicolon is the correct mark to separate these two independent clauses. A colon is incorrect because the second clause does not explain or expand on the first, and a comma would result in a comma splice.
Semicolons are the standard tool for connecting independent clauses without coordinating conjunctions when a colon's explanatory relationship is absent.
