Some coral reefs are damaged to such a large degree that neither

OFFICIAL EXPLANATION



THE PROMPT

• ISSUES
→ Neither must be paired with nor

→ In neither X nor Y, the X and Y elements must be parallel

→ So X that Y is tested fairly often
So X that Y indicates results. Attribute X is so extreme in this case that Y results.

THE OPTIONS


• the sentence is grammatical, but typically we would say, ". . . damaged to such a degree that . . . "
→ such in that case would mean "of so extreme a degree or quality," as defined here.
• the phrasing is a bit inelegant, but otherwise I see no errors
KEEP, but look for a better answer.

• The meaning and idiomatic usage are fine.
→ The reefs are so damaged that P and Q cannot restore the reefs.
• The X and Y elements in Neither X nor Y are not as parallel as they could be
X = government protection
Y = the awareness of the public
Either X should be the protection of the government or Y should be public awareness so that the X and Y elements are parallel

Still, I do not see enough error to eliminate this choice.
KEEP, but look for a better answer.

• This option is better than (A) and (B)
→ so damaged that is more succinct and more idiomatic than to such a large degree
→ government protection (the X element) and public awareness (the Y element) are parallel
ELIMINATE A AND B.
KEEP C


• neither, if paired, is always paired with nor.
Neither is never paired with or.
ELIMINATE D


• to a large enough degree is just all kinds of wrong
→ We have already determined that option C is better than option A, and option E is not much different from option A (in fact, (E) is worse).
Again, we might say "to such a degree," but even that phrase is less concise than "so damaged that."
Option C is better than E.
ELIMINATE E

The answer is C.
