Sentence Correction: Comparatives - Like/Unlike

Dogs, like cats, produce a hormone known as relaxin during the pregnancy period.

This answer choice is grammatically incorrect. The like section should not include a conjugated verb. In this answer choice, however, the like section includes a conjugated verb (like cats do).

What helps us identify this question as a Comparative question as well as identify the mistake is the following Stop Sign:

Like, unlike, than, as

This answer choice is grammatically incorrect. The like section should not include a conjugated verb. In this answer choice, however, the like section includes a conjugated verb (like cats do).

What helps us identify this question as a Comparative question as well as identify the mistake is the following Stop Sign:

Like, unlike, than, as

This answer choice is grammatically flawed because it uses the incorrect preposition on before the pregnancy period . The correct idiom is during the pregnancy period. The preposition during represents a period of time that passes while another action is taking place.

This answer choice is stylistically flawed. The use of the word like and similarly in the same sentence creates redundancy since they mean the same thing.

Well done!
