In the sentence "Offering her license and registration, Selena sobbed in the driver's seat," offering is not a gerund, right? It isn't a noun and does not act as a subject. That made me wonder if the main verb is offering or sobbed.
I'm having a hard time trying to identify the main verb and phrase verb. Actually I'm wondering if in my last sentence the main verb was trying or identify.
One last question: In the sentence "The man is watching the birds," is the main verb watching? or is? and why?
Please, any help is welcome.
