A sentence that just keeps going without any pauses
Answer:
it is a participal phrase
I don’t understand you’re question, who will be late and for what.
Where is the fragment? This makes no sense
B. After
A preposition is a word that comes before a noun that tells the reader where one noun is in relation to another noun. In the sentence, after tells when she ended the dinner. In this case "After a disastrous dinner" is the entire prepositional phrase. Sometimes the word to is considered a preposition. However, in this case, it is part of the infinitive form of the verb end.
