Question

Which of these situations qualify as plagiarism

Answer 1

Plagiarism is when you copy someone else's work (usually word by word) and you do not acknowledge that you where not the person who wrote it, also, you do not cite where you received that info from. That is why we have copyright laws, where the author can choose whether to establish a penalty if copied. 

Answer 2

Plagiarism is copying something directly from something else.
