Answer:
The author used dialogue skillfully to heighten the tension and to reinforce the mood.
Step-by-step explanation:
Prepositional phrases are groups of words that consist of a preposition, its object, and words that modify the object. A prepositional phrase used in the given sentence is with skill.
However, it would be better to use an adverb of manner instead of this prepositional phrase. Adverbs are words used to modify verbs, adjectives, and other adverbs. Adverbs provide us with a variety of information, including manner.
The adverb that should be used here is skillfully (derived from an adjective (skillful) derived from the word skill). It modifies the verb used. To confirm this, we can ask:
- How did the author use dialogue?
- Skillfully/ With skill.
