This question is incomplete; here´s the complete question.

In the case below, the original source material is given along with a sample of student work. Determine the type of plagiarism.

Original Source Material

A communication channel is the means by which messages get from one individual to another.The nature of the information-exchange relationship between a pair of individuals determines the conditions under which a source will or will not transmit the innovation to the receiver and the effect of such a transfer.

Student Version

Rogers places great importance on the sharing of information about an innovation. He defines a communication channel as “the means by which messages get from one individual to another” (p. 18). He describes two general media channels of communication: mass media and interpersonal; and two scopes of channels: localite and cosmopolite.

Which of the following is true for the Student Version above?

Word-for-Word plagiarism

Paraphrasing plagiarism

This is not plagiarism

Answer: Word-for-Word plagiarism

Explanation:

The student version is Word-for-word plagiarism because it uses ideas from the source material, and takes over seven words in sequence from it, but it is missing the corresponding date

The correct version would be: (Rogers, 2003, p.18)
