Which action best demonstrates a reader's engagement with entertaining content?

Choosing laughing as the best action that demonstrates a reader's engagement with entertaining content is appropriate because laughter indicates that the reader is experiencing joy or amusement while interacting with the material. This emotional response signifies that the content has captured the reader's interest and has effectively entertained them, which is a key aspect of engaging with entertaining content.

Engagement in this context is often measured by the reader's emotional reactions. Laughter reflects the reader's enjoyment and connection to the stories or themes presented, suggesting they are not just passively consuming the information but are actively involved and responsive to it. In contrast, taking notes, summarizing, or questioning the author generally align more with analytical or critical reading practices rather than pure enjoyment, which is foundational to the experience of entertaining content.
