there are two parts after although clause which should give negative aspects and should be parallel.

Their cannot logically refer to anything other than fertilisers; it cannot denote productivity, becos productivity is singular and their is plural; it cannot point to parts of the world,as no one can materially increase parts of the world and leave alone use them to create problems

B and E out because of Like.

D While if is incorrect

C - grammatically correct but it is too wordy where A says the same very concisely.

Hi fozzy.

Whereas the use of synthetic fertilizers has greatly expanded agricultural productivity in many parts of the world, an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers may accelerate soil structure deterioration and soil erosion.

A. an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers
Correct. The use of "their" is quite ambiguous, so I don't think this sentence sounds smoothly. A, however is the best among all options.

B. an increase in their use can create serious environmental problems like water pollution, and if substituted for more traditional fertilizers, it
Wrong.
- "like" is incorrect, like = similar to. However, wee need examples here, thus "such as" is appropriate.
- We're talking about "fertilizers" (plural) ==> "it" is wrong.

C. if these fertilizers are used increasingly, they can create serious environmental problems such as water pollution, and if used as substitutions for more traditional fertilizers, they
Wrong.
- Parallelism: The structure of C is: whereas the use of X has greatly expanded........, if X are used, and if ......
==> in order to make a sentence parallel, the structure should be: whereas the use of X greatly expanded......, in increase in their use.......
==> "the use of X" || "their use"
- Meaning: "an increase in the use of synthetic fertilizers" DIFFERS from "the fertilizers are used increasingly"
For example:
(1) The increase in the use of computers ==> computers become more popular, so many people use them. (horizontal)
(2) The Computers are used increasingly ==> These particular computers are exploited (vertical)

D. the increased usage of these fertilizers can create serious environmental problems such as water pollution, while if substituted for more traditional fertilizers, this substitution
Wrong.
- Modifier problem: "if substituted for more ..., this substitution may accelerate .........." Verb-ed modifier + COMMA ==> ALWAYS modify subject. The subject of the second part is "this substitution" ==> The meaning will be: if substitution are substituted for more...... ==> Does not make sense at all.
- "While" is subordinating conjunction ==> does not match the overall meaning of the structure. Coordinating conjunction "and" is more appropriate.

E. the increased usage of these fertilizers can create serious environmental problems like water pollution, while their substitution for more traditional fertilizers
Wrong.
- "like" is wrong ==> "such as" should be correct.
- "while" changes meaning. ==> "and" should be correct

Hope it helps.

The word THEIR in Option A makes it the correct answer.

B & E are out for us of LIKE and other reasons as discussed.

If you compare A with C & D-
The usage of COMMA + AND rule (,and) makes A the winner. When you have two clauses separated by a Comma you must have a subject in each one the clauses. By intrpcuding THEIR (subject pronoun for Fertilizers) A makes it clear what we are talking about.

Earl walked to school, and later ate his lunch (WRONG- since HE is missing).


C. if these fertilizers are used increasingly, they can create serious environmental problems such as water pollution, and if used as substitutions for more traditional fertilizers, they (what is IF used as substitution)
D. the increased usage of these fertilizers can create serious environmental problems such as water pollution, while if substituted for more traditional fertilizers, this substitution (what is if substitued)

But in A , In underlined portion ...an increase is the subject , which is singular, hence verb use must be singular not plural.

Use is singular ????

Hello.

"Use" is noun form, NOT verb form. The compund noun is "an increase in their use". Main verb is "create". After modal verb "can", we use bare verb form - "create".

Hope it helps.

Whereas the use of synthetic fertilizers has greatly expanded agricultural productivity in many parts of the world, an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers may accelerate soil structure deterioration and soil erosion.

The structure is Whereas X, Y -> X and Y should be parallel and should be clauses.

(A) an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers -> Looks good. this option is parallel -> whereas the use of X, an increases in their use of Y

(B) an increase in their use can create serious environmental problems like water pollution, and if substituted for more traditional fertilizers, it

(C) if these fertilizers are used increasingly, they can create serious environmental problems such as water pollution, and if used as substitutions for more traditional fertilizers, they

if used as substitutions for more traditional fertilizers -> what is used?
The subject of the sentence is ellipsed. So we can repeat that subject as
if these fertilizers are used increasingly, they do X, and if these fertilizers are used as substitutions for more traditional fertilizers, they do Y .
Instead of that, we can use "and if these fertilizers are substituted for more traditional fertilizers, they do Y" -> We can eliminate this option based on redundancy.


(D) the increased usage of these fertilizers can create serious environmental problems such as water pollution, while if substituted for more traditional fertilizers, this substitution

while is used as but for contrast.
what is substituted?
Since we have a "while", we can repeat the subject which is "the increased usage of these fertilizers substituted for more traditional Fertilizers" -> Wrong sense.
this is pronoun and cannot refer to the clause.


(E) the increased usage of these fertilizers can create serious environmental problems like water pollution, while their substitution for more traditional fertilizers

C: Wrong; For Whereas X, Y; X and Y must be clauses
A versus D:
D: Wrong; looked good, BUT it was wrong, because "if substituted...fertilizers" should not modify "substitution"

B,E - out for using "like" to show example
C- incorrectly uses "substitutions" instead of "substitutes" -- you can use something as substitute, not substitution.
D- "while if" is awkward. while also suggests that two actions are happening together, which is not the case here.

Ans: "A"


Hey Fluke,

Does isnt 'their' in A ambiguios ?
Does their refer to fertilizers or productivity ?? How do we know ?


"Their" can refer to plural antecedent fertilizers not the singular antecedent productivity. Correct me if I am wrong.

Hey Fluke,

Hi,


“their" refers to plural antecedant fertilizers. Productivity is singular. "Their" cannot refer to singular noun.

As a rule, to find out countable and uncountable nouns - put 1,2,3 before the noun and check if the phrase makes sense. If YES the noun is countable (plural form exists) and If NO the noun in uncountable (plural form doesn't exist)

1 fertilizer, 2 fertilizers etc - make sense. Fertilizer - Countable

1 productivity, 2 productivity etc - doesn't make sense. Productivity - Uncountable

Hope this helps.

"Their" in option A is not ambiguous it refers to fertilizers (plural). Productivity is singular, "their" can not refer to productivity.

Whereas the use of synthetic fertilizers has greatly expanded agricultural productivity in many parts of the world, an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers may accelerate soil structure deterioration and soil erosion.

A. an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers
B. an increase in their use can create serious environmental problems like water pollution, and if substituted for more traditional fertilizers, it
C. if these fertilizers are used increasingly, they can create serious environmental problems such as water pollution, and if used as substitutions for more traditional fertilizers, they
D. the increased usage of these fertilizers can create serious environmental problems such as water pollution, while if substituted for more traditional fertilizers, this substitution
E. the increased usage of these fertilizers can create serious environmental problems like water pollution, while their substitution for more traditional fertilizers

I removed A for "Their substitution" that conveys a different meaning.

Intention is to say " If they are used as a substitution, they accelerate soil structure deterioration and soil erosion." Their substitution - synthetic fertiliser substitution, that sounds wrong.
