A known cause for the failure of barley crops is poor aeration of the soil and in particular the seedlings' root zone, but since the introduction of new strains, which are more resistant to waterlogging, barley has survived better after seasonal floods.

OFFICIAL EXPLANATION
A known cause for the failure of barley crops is poor aeration of the soil and in particular the seedlings' root zone, but since the introduction of new strains, which are more resistant to waterlogging, barley has survived better after seasonal floods.
(A) aeration of the soil and in particular the seedlings' root zone, but since the introduction of new strains, which are more resistant to waterlogging, barely has survived better after seasonal floods
Incorrect.
This answer choice is grammatically incorrect. The construction A and B (poor aeration of the soil and ... the seedling's root zone) requires that A and B be grammatically parallel and logically parallel.
However, while poor aeration of the soil is a logical cause for crop failure, the seedling's root zone is not. This indicates that the logical parallelism should be between aeration of the soil and [aeration] of the seedlings' root zones.
Look for answer choice that constructs this parallelism logically and grammatically.
What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:
- A and/or/but B
1. A and B must be of the same part of speech.
2. A and B must be logically parallel.
(B) soil aeration, particularly the seedlings' root zone, but barley is surviving the seasonal floods better, after new strains were introduced, which are more resistant to waterlogging
Incorrect.
This answer choice is grammatically incorrect. The relative clause which are more resistant to waterlogging logically refers to the noun strains and should therefore immediately follow it. However, it follows the verb introduced.
What helps us identify this question as a Relative Clause question as well as identify the mistake is the following Stop Sign:
- whose, which, that, whose, whom
In addition, this answer choice is illogical. The modifier particularly the seedlings' root zone does not logically modify the noun soil aeration, which precedes it. It should logically be soil aeration, particularly the aeration of the seedlings' root zone.
(C) aeration of the soil and particularly that of the seedlings' root zone, but since the introduction of new strains, which are more resistant to waterlogging, barley has survived better after seasonal floods
This answer choice corrects the original Parallelism mistake by changing in particular the seedlings' root zone to particularly that of the seedlings' root zone. The new construction creates a grammatically correct and logical parallelism between two items that describe causes for crop failure.
Note that the parallelism consists of aeration of the soil and that of the seedlings' root zones. The pronoun that refers to aeration.
What helps us identify this question as a Parallelism question as well as identify the mistake is the following Stop Sign:
- A and/or/but B
When you identify this structure, make sure it follows these rules:
1. A and B must be of the same part of speech.
2. A and B must be logically parallel.
(D) soil aeration and in particular that of the seedlings' root zone, but barley are surviving better after seasonal floods, since the introduction of new strains which are more resistant to waterlogging
Incorrect.
This answer choice is grammatically incorrect. It introduces a Subject Verb Agreement mistake: the singular noun barley does not agree with the plural verb are.
(E) aeration of the soil, but since the introduction of new waterlogging-resistant strains and in particular of the seedlings' root zone, barley crops are better surviving seasonal floods
Incorrect.
This answer choice changes the original meaning of the sentence. Moving the phrase in partucular of the seedling's root zone makes it parallel to new waterlogging-resistant strains, but it should be parallel to poor aeration of the soil:
- Original: ... is (a) poor aeration of the soil and [in particular] (b) the seedlings' root zone ...
This answer choice: ... but since the introduction (a) of new waterlogging-resistant strains and [in particular] (b) of the seedlings' root zone ...
