Answer:
Type of Verbal: Gerund phrase
Verbal Phrase: Crossing the street on a red light
Step-by-step explanation:
A gerund phrase is a verbal phrase that consists of a gerund (which it's made up of the verb root of a verb + -ing) and modifiers of that object, and sometimes, it also includes objects. The primary function of this type of phrases is to act as a noun, therefore they can be subjects, objects or complements.
In the sentence, "Crossing the street on a red light" is the gerund phrase because it has a gerund (Crossing), an object (the street) and modifiers ( on a red light). Furthermore, it is also the subject of the sentence because it is what's being described.
