passage: ancient oral cultures developed cultural tools such as songs and encyclopedic poems that could be remembered and passed to the next generation, but oral poems are not fixed; they change from performance to performance. moreover, there were limits on how much information could be packed into an oral song, and if the singer died before he could train an heir, the string of an oral tradition might be broken permanently.

instructions
according to dutton, marchand, and harkness in many europes, ancient oral cultures developed cultural tools such as songs and encyclopedic poems. information was handed down as each new generation memorized the songs and poems. however, the songs were not stable; a song or poem might change each time it was recited. in addition, songs and poems can only convey a limited amount of information. and, if one generation failed to learn a song, its information was lost forever.

Explanation:

Plagiarism occurs when a writer uses the exact words or structure of the original source without proper citation. In the summary, the sentence "However, the songs were not stable; a song or poem might change each time it was recited" closely mirrors the original passage's "oral poems are not fixed; they change from performance to performance". This is an instance of plagiarism as it directly copies the idea and structure without rephrasing or proper attribution.

Answer:

However, the songs were not stable; a song or poem might change each time it was recited.
