Active galactic nuclei are some of the most energetic phenomena in the universe, frequently influencing the evolution of their host galaxies. Recently, astronomers studying the hyperluminous infrared galaxy W2246-0526 observed massive outflows of gas turbulent enough to destabilize the interstellar _______ outflows are likely driven by the intense radiation pressure generated by the central supermassive black hole.

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

  1. A
    medium, these
  2. B
    medium, but these
  3. medium; theseCevap
  4. D
    medium these

Cevap

The choice 'medium; these' correctly completes the text by using a semicolon to link the two independent clauses.
The correct answer is the option that uses a semicolon to separate the two independent clauses: 'medium; these'. A semicolon is a standard and grammatically correct method to link two closely related independent clauses without the need for a coordinating conjunction.

Adım Adım Çözüm

1
Identify the structure of the clauses before and after the blank.
The first clause ('Recently, astronomers studying the hyperluminous infrared galaxy W2246-0526 observed massive outflows of gas turbulent enough to destabilize the interstellar medium') is independent. The second clause ('these outflows are likely driven by the intense radiation pressure generated by the central supermassive black hole') is also independent.
Determining clause type is necessary to apply the correct punctuation and linking rules.
2
Analyze the logical relationship between the two independent clauses.
The second clause explains the cause or mechanism behind the outflows described in the first clause. There is no contrast between the two statements.
Understanding the logical connection helps determine whether a coordinating conjunction like 'but' is appropriate.
3
Evaluate the options to find the grammatically and logically correct way to link the clauses.
The option using a semicolon without a coordinating conjunction ('medium; these') is grammatically correct and preserves the logical flow. The option with a comma alone creates a comma splice. The option with no punctuation creates a run-on. The option using 'but' incorrectly introduces a contrastive relationship.
Standard English conventions require independent clauses to be separated by a period, a semicolon, or a comma paired with a coordinating conjunction that logically fits the context.
