Read the scenario for each student. Which student la are engaging in plagiarism

Shane's paper on Shakespeare's sonnets lacks originality because he has passed off his brother's work as his own. That amounts to plagiarism.

Because Dan has cited all the sources he used for his paper about immigrant literature in the bibliography, his work is not plagiarized.

Because Molly has cited all the quotes she used from Jack Kerouac's books in the bibliography, her work is not plagiarized.

Because Maya has not cited some of her online sources in the bibliography, her work will be regarded as plagiarized material.

Can I have the scenarios/more information?
