OFFICIAL EXPLANATION
John gets along and likes Jane's brother.A. gets along and likes
This answer choice is grammatically incorrect.
The verb gets in the Split Construction gets along and likes is missing a preposition. Despite already including a preposition, gets along requires another preposition in order to correctly connect to Jane's brother. You don't get along someone - you get along with someone.
What helps us identify this question as a Split Construction question and identify the mistake is the following Stop Sign: A split construction: Verb A + and/or + Verb B + objectB. gets along and like
This answer choice repeats the original mistake.
In addition, this answer choice creates a Subject Verb Agreement mistake by turning the singular verb likes into the plural like.C. gets along with and likes
This answer choice adds the required preposition to the Split Construction - with.D. get along and likes
This answer choice repeats the original mistake.
In addition, this answer choice creates a Subject Verb Agreement mistake by turning the singular verb gets into the plural get.E. not only gets along but also likes
This answer choice repeats the original mistake.
In addition, this answer choice is stylistically flawed. The addition of not only... but also creates redundancy.
