Final answer:
The correct prepositional phrases in the given context are "in the barn" and "to the pasture", which provide information about location and direction.
Step-by-step explanation:
A prepositional phrase is a group of words that begins with a preposition and ends with a noun or pronoun, known as the object of the preposition. In the provided context, the correct prepositional phrases are "in the barn" and "to the pasture." These phrases add information about location and direction. Therefore, the correct answer to the question is option (a) "in the barn," "to the pasture."
Prepositional phrases can function as adjectives or adverbs, depending on whether they modify a noun or a verb. For instance, in the sentence "The pony usually stays in the barn, but we let her out to the pasture on sunny days," the phrase "in the barn" tells us where the pony usually stays, and "to the pasture" tells us where the pony is let out.
