Step 1: Understanding syntactic recursion
Syntactic recursion occurs when one phrase of a given type is nested inside another phrase of the same type. For example, verb phrases (VPs) may contain prepositional phrases (PPs), or noun phrases (NPs) may contain relative clauses.
Step 2: Analyzing each option
- (A) \emph{The wolves ran on steadily.}
This is a simple verb phrase: \emph{ran on steadily}. The words \emph{on steadily} are just an adverbial modifier, not an embedded phrase. There is no recursive embedding here. Hence, this sentence does not exhibit syntactic recursion.
- (B) \emph{The wolves ran in the night.}
Here, the verb phrase \emph{ran} contains a prepositional phrase (PP: \emph{in the night}). This is recursion because a phrase structure is embedded within the verb phrase.
- (C) \emph{The deer avoided the wolves.}
Although structurally simple, the object \emph{the wolves} forms a full noun phrase (NP) embedded within the verb phrase (VP). This counts as recursion.
- (D) \emph{The deer quietly stood nearby.}
The verb phrase \emph{stood nearby} includes an embedded adverbial modifier \emph{quietly}, showing recursion.
Step 3: Conclusion
Only (A) is a flat, non-recursive structure. All others show some form of syntactic embedding.
