You find some material on a website and use it as an idea for an assignment. the material just inspires you, and you don't use any material directly from the page. you write your assignment entirely in your own words, and use no direct quotes from the original site. you don't cite your source. is this plagiarism?

No its not unless you claim that its your own and use it word for word.

The answer is letter B-- predicate adjective. 

A predicative adjective could be one adjective or a phrase which includes an adjective and other modifiers. In the given sentence above, hoarse acts as a predicate adjective. 

A predicate nominative, on the other hand, is a noun or a pronoun that always follows the verb and renames or describes the subject. 

Direct object and indirect object are far from the correct answer.
