In 1915, Albert Einstein published his theory of general relativity, which revolutionized modern physics. This groundbreaking work, a mathematical framework that describes gravity as the warping of spacetime, challenged Newton's classical laws. Scientists around the world immediately began testing its predictions.
Which of the following is the best replacement for the underlined portion of the passage?
- NO CHANGECevap
- Bwork, a mathematical framework that describes gravity as the warping of spacetime
- Cwork, a mathematical framework, that describes gravity as the warping of spacetime,
- Dwork; a mathematical framework that describes gravity as the warping of spacetime,
Cevap
The correct answer is the option that maintains a pair of commas to set off the nonessential appositive phrase without separating the restrictive clause from its referent.
The underlined portion introduces a nonessential appositive phrase ('a mathematical framework that describes gravity as the warping of spacetime') that modifies the noun phrase 'This groundbreaking work'. Nonessential appositives must be set off from the rest of the sentence by a pair of commas: one before the appositive and one after. The original text correctly places a comma after 'work' and a comma after 'spacetime'. Additionally, the relative clause 'that describes gravity as the warping of spacetime' is restrictive (essential to the meaning of the appositive framework) and should not be separated from 'framework' by a comma.
