Question

Read the generative grammar phrase structure rules.

S -> NP + VP

NP ->(DET) N

VP -> V (NP)

Which of these is a kernel sentence that would match these phrase structure rules?

Did Sally shave the cat?
The cat was shaved by Sally.
Sally, don't shave the cat!
Sally shaved the cat.

Answer 1

The fourth sentence is the correct answer

Answer 2

Answer:

Sally shaved the cat.

Explanation:

Kernel sentences are basic constructions with only one single verb, which is affirmative and active.

The rest of the alternatives are incorrect because Did Sally shave the cat?  is interrogative, The cat was shaved by Sally contains passive voice, and Sally, don't shave the cat!  is a negative command.
