Final answer:
The prepositional phrases in the given sentences are 'on the viaduct', 'in Chicago', 'of flowers' and 'to my office', and 'around the campfire'. They contain a preposition and the object it relates to, and modify verbs or nouns in the sentence.
Step-by-step explanation:
To identify and write the prepositional phrases in the given sentences, we first need to find the preposition and then the object it is related to. Here are the sentences with the prepositional phrases in bold:
- a. Did your car stall on the viaduct?
- b. My sister lives in Chicago.
- c. A large bouquet of flowers was delivered to my office.
- d. Our family sat around the campfire.
Each prepositional phrase begins with a preposition ('on', 'in', 'of', 'to', 'around') and includes the object it relates to (e.g., 'the viaduct', 'Chicago', 'flowers', 'my office', 'the campfire'). These prepositional phrases can act as adverbials or adjectives in the sentence, modifying nouns or verbs.
