This is the sentence that contains a mistake. In this sentence, the author wrote the word "do" instead of the word "due." The first one is a verb and it refers to taking some action (<em>to do</em> something). "Due to" on the other hand, is an idiom that means "attributable to" or "because of." These words are homophones. Homophones are words that are pronounced the same but have different meanings, and sometimes spelling.

It depends on which word is in bold. If the bolded word is <em>ribbon, </em>then it is used as a direct object in this sentence. The winner is indirect object, and a ribbon is direct.
