222. Contrary to earlier conjectures, it may be that increased atmospheric carbon dioxide as a result of burning fossil fuels would cool the globe by reducing the amount of solar energy absorbed by snow. (A) increased atmospheric carbon dioxide as a result of burning--Incorrect (B) increased atmospheric carbon dioxide resulting from the combustion of (C) increasing carbon dioxide in the atmosphere resulting from the combustion of (D) carbon dioxide in the atmosphere that increase from burning (E) atmospheric carbon dioxide that increased from burning--Incorrect
Why is B the answer and not C in the solution? pls explain?
a) you can't use "as a result of" to modify a noun; it can only modify a clause. for instance, you can say carbon dioxide levels increased as a result of... but you can't say the carbon dioxide as a result of ... did this.
(c) * wordy in comparison to (b) * because there's no comma before the modifier resulting from the combustion..., that modifier technically modifies the adjacent noun atmosphere. that's nonsense, of course: the atmosphere didn't result from the combustion of fossil fuels (not to mention that this writing suggests the existence of more than one atmosphere).
