Sentence Correction: Preposition Questions - Split Constructions

Canines have evolved as pack animals, and their behavior is closely linked to this social evolution, so in order to prevent abnormal conduct, an owner must learn to care and dominate the animal simultaneously.

This answer choice is grammatically incorrect. The verb care requires a preposition in order to correctly connect to the animal. One cannot care an animal - one can care for an animal.

Whenever the first verb requires a preposition after it and the second verb does not, the preposition must not be omitted:

Incorrect: John cares and loves Jane.
Correct: John cares for and loves Jane.

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 + object

Although this answer choice corrects the original Split Construction error by adding the preposition for, it is grammatically incorrect because it uses an incorrect preposition (as) in the phrase as this social evolution. The correct idiom is linked to.

Fantastic work!

The verb care requires a preposition in order to correctly connect to the animal. This answer choice solves this error by adding the preposition for.

Note that this answer choice changes the subject to "behavior and social evolution", a plural subject, which requires the concurrent shift to a plural verb "are". The other answer choices correctly match a singular subject "behavior" with a singular verb "is", so SVA is not an issue in this question - the other answer choices are eliminated for other reasons of redundancy/incorrect use of prepositions.

Although this answer choice corrects the original Split Construction error by adding the preposition for, it creates redundancy by using the passive form in the phrase be cared for and dominated by the owner. Since there is another grammatically correct answer choice that does not use the passive form, it is preferable to this one.

Although this answer choice corrects the original Split Construction error by adding the preposition for, it creates Redundancy by using the word simultaneously and the phrase at the same time in the same sentence since they mean the same thing.
