Which of the following trees corresponds to a potential parse of the ambiguous sentence below, with correct syntactic categories? Some diagnostics are provided.

Which of the following sentences contain two non-finite verbs? Select all that apply.

The syntactic head of a phrase is the most important element of a phrase and whose category defines the phrase's [ Select ] exponent movement distribution head . Single words or phrases that form part of a phrase but are not the head are called [ Select ] head complement dependent argument modifier . This classification can be further divided into: 1) [ Select ] arguments modifiers complements dependents heads , which have a closer relationship to the head, and are not easily reordered and 2) [ Select ] arguments complements dependents heads modifiers , which have a much looser connection to the head and can often be reordered with other [ Select ] heads modifiers complements dependents arguments . Consider the concrete example: "a strong cup of coffee" and the following diagnostics. In this example, "cup" is a [ Select ] dependent complement argument head modifier , "of coffee" is a [ Select ] argument dependent complement head modifier , "strong" is a [ Select ] argument modifier complement head dependent , and "a" is a [ Select ] modifier dependent head dependent complement .
