Correct answer!
Tip:
Copyright can be infringed either by using the whole work or also using a substantial part of the work without permission of the copyright owner, therefore legal action can be taken against the infringer.
Best Practice:
A 'substantial' part of the work has been copied if the infringer has taken the "author's intellectual creation".
To determine what is 'substantial', a qualitative test is undertaken, not a quantitative one, because the infringement can be of a small, but at the same time significant, portion of the original work .
Infringing uses include copying, republication, dramatization, performance in public and it leads to legal action taken againsts the infringer.
