Read the sentence. When soccer practice was over, I saw Monica riding a skateboard in the park, so I stopped, and we talked for awhile. Which part of this sentence is a phrase? "when soccer practice was over" "riding a skateboard" "so I stopped" "we talked"

If we look at the part of the sentence "when a football practice was over" we can say that it is a recurring action periodically and it represents a routine, but that's not a phrase because it is stated specifically, what is the issue. "I stopped" also suggests a concrete action, therefore, it's not a phrase, because it explicitly indicates what has been done. What is the phrase in this sentence is a cluster of words without a finite verb, and having that in mind, the correct answer is "riding a skateboard".

Answer: riding a skateboard is the correct answer
