Zorluk: ZorClause Boundaries and Linking

Glaciologists studying the West Antarctic Ice Sheet have identified several deep subglacial lakes that periodically fill and drain beneath thousands of meters of ice. The sudden drainage of these massive reservoirs can cause the overlying glacier to accelerate ________ this surge is typically temporary, subsiding once the water basin is completely depleted.

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

  1. A
    dramatically, however,
  2. dramatically; however,Cevap
  3. C
    dramatically however
  4. D
    dramatically, so

Cevap

dramatically; however,
The passage presents two independent clauses: 'The sudden drainage of these massive reservoirs can cause the overlying glacier to accelerate dramatically' and 'this surge is typically temporary, subsiding once the water basin is completely depleted.' To connect two independent clauses, a semicolon followed by a conjunctive adverb and a comma ('dramatically; however,') is grammatically correct and logically appropriate, as it establishes a contrast between the glacier's acceleration and the temporary nature of the surge.

Adım Adım Çözüm

1
Identify the structure of the clauses before and after the blank.
The text before the blank ('The sudden drainage of these massive reservoirs can cause the overlying glacier to accelerate') and the text after the blank ('this surge is typically temporary...') are both independent clauses.
Determining whether the clauses are independent or dependent dictates the type of punctuation and conjunctions required to link them.
2
Determine the logical relationship between the two independent clauses.
The second clause introduces a contrast to the first clause (the acceleration is temporary, contrary to what might be expected from a sudden acceleration).
Selecting the correct transition word requires understanding how the ideas in the two clauses relate to each other.
3
Select the punctuation and transition that correctly links the independent clauses and expresses contrast.
A semicolon followed by the transition 'however' and a comma ('dramatically; however,') correctly separates the independent clauses while expressing contrast.
Two independent clauses cannot be joined with just a comma and a transition (comma splice) or no punctuation (run-on), and the transition must match the contrast relationship.
