For Risa's oral presentation about Bob Dylan and the cultural impact of his music, she should include the following multimedia sources:
- a podcast in which Dylan’s life and work are discussed: This can provide insights and commentary on Dylan's impact and significance.
- an audio clip of one of Dylan’s most influential songs: Listening to his music can illustrate his style and impact directly.
- a photograph of Dylan performing at a concert: Visuals of Dylan in performance can enhance the presentation and evoke the energy of his live shows.
Including these sources would create a well-rounded presentation that combines audio, visual, and textual elements. While a recording of his most influential album and an article about his influence are valuable, they are less immediately engaging in a short oral presentation format compared to the selected multimedia options.
