Answer:
The adverb in the sentence above is only soon.
Step-by-step explanation:
Adverb is the word or phrases that different taste to the verb. It modifies the verb used. “Soon” in the above sentence determines the manner of being fast. We can also check adverbs by questioning “where”, “when”, “how” etc.
The “church “in the sentence determines the place and do not modifies any meaning of the verb, hence “only soon” is the adverb there.
