C. nutrients, such as phosphorus, that enters a body of water plays a major role in. --Such as phosphorous --that is set off in commas is the inessential modifier that can be ignored --- correct choice

D. nutrients such as phosphorus that enter a body of water are a major part of -- are a major -- SV error. Reducing (the nutrients) is the singular subject ; we need to uses a singular verb i.e., is

'that enter a body of water' is a required clause and must modify nutrients not phosphorus. Classic example of misplaced modifier.

Ans B it is!

Always remember "clauses are singular entities".
"that" can't be preceded by a comma unless its a part of modifier.

A) Incorrect usage of "that"
B) "phosphorus" seems to be an example of "body of water"
c) Coorect. All the issues have been resolved
D) treats the clause as plural
E)"which" modifies P. Also "which" is incorrectly used.

Hi Marcab,

What role does "that" play when it is preceded by a comma and is not part of a modifier? I am not clear with the usage of "that" and finally I ended up choosing option A.

Also is "central to" idiomatically correct?

Thanks.

Not sure if you posted the correct question. Option C requires verb "enters" and not "enter" since the verb is modifying phosphorus. Please mention the source of the question.

Hi Chanakya,

Actually 'that' is modifying nutrients. It is correct, no problem.
the phrase 'such as phosphorus' is an optional statement to give more details on nutrients.

Hope it helps!

Hey the right answer choice is C here.

Always Remember:
If the "which" is after a preposition, the comma is not required.
Else the comma is required always as which is the non essential modifier.

My thinking process -

A. nutrients such as phosphorus, that enter a body of water, is central to - Incorrect
B. nutrients that enter a body of water such as phosphorus is key to - Incorrect
C. nutrients, such as phosphorus, that enter a body of water plays a major role in - most qualifying answer among all
D. nutrients such as phosphorus that enter a body of water are a major part of - not clear whether that is referring to nutrients or to phosphorus
E. nutrients such as phosphorus which can enter a body of water, hold the key - which should be separated with a comma (,)

As algae spread in freshwater ponds and lakes, water quality decreases; thus, reducing the nutrients such as phosphorus, that enter a body of water, is central to reducing algae, which thrive on certain pollutants.

1)meaning:
with spread of algae in freshwater, the water quality decrease; reducing the nutrients is central to reducing algae

2) error analysis:
that introduces essential modifier so we cannot sandwich it!
second and most important point is that .. these nutrients can enter the body of water.. so we have modification error

3) POE

A. nutrients such as phosphorus, that enter a body of water, is central to modifier error
B. nutrients that enter a body of water such as phosphorus is key to misplaced modifier .. such as phosphorus seems to modify a body of water
C. nutrients, such as phosphorus, that enter a body of water plays a major role in
D. nutrients such as phosphorus that enter a body of water are a major part of S-V error... reducing nutrients is
E. nutrients such as phosphorus which can enter a body of water, hold the key again modifier error.. it seems that just phosphorus can enter the body of water while in correct version nutrients can enter the body of water

In the choice C , the word "Plays" should be "Play" right ? since it has to refer to a plural noun "Nutrients" ... can you please explain

Dear gauravsoni,

The subject of "plays" is the gerund "reducing", which is singular.

Reducing (the nutrients (,such as phosphorus,) that enter a body of water) plays a major role in blah-blah.

The portion between "reducing" and "plays" just serves to identify the object of "reducing."

For example, see:
Singing the songs of Elvis is always a lot of fun.

What is fun? Singing, not the songs.

Can you clarify that with an example? Also, is it idiomatic to right a sentence this way - reducing nutrients plays an major role in...

A. nutrients such as phosphorus, that enter a body of water, is central to
- that enter a body water is used to modify nutrients and is an essential modifier, so its usage is wrong here
B. nutrients that enter a body of water such as phosphorus is key to
- the key to do something not the key to doing something
C. nutrients, such as phosphorus, that enter a body of water plays a major role in
CORRECT, play a major role in ... is idiomatic.
D. nutrients such as phosphorus that enter a body of water are a major part of
that enter a body of water here modifies phosphorus
E. nutrients such as phosphorus which can enter a body of water, hold the key
similar to D

I have a doubt about option "C".
"Nutrients" is plural, which requires a plural verb "Play". Option "C" uses "Plays".

Can someone clear my doubt.

B is probably the worst of the lot for "nutrients enter a body of water...is"
D changes the meaning in "are a major part of reducing algae"
E is incomplete in "hold the key reducing algae"

It's between A and C. "Plays a major role in" in C conveys the intended meaning more appropriately.
Therefore, C

Intended meaning is that "reducing the nutrients" plays a major role in reducing algae.
