Read the excerpt from Neil deGrasse Tyson's "Death by Black Hole.

Read the excerpt from Billy Collins's "Man Listening to Disc."
This is not bad-
ambling along 44th Street
with Sonny Rollins for company,

Which of the following ideas is presented in both excerpts?

- The human body is being moved along by an outside force.

Explanation:

'Death by Black Hole' authored by Neil deGrasse Tyson details the significance of our senses in advancing the scientific understanding while Billy Collins's 'Man Listening to Disc' discusses the sensory impressions evoked through music('jazz').

As per the question, the key idea that is being discussed in both the given excerpts would be 'the human body is being moved through an outside force('black hole' in the first and 'music' in the second). The idea is clearly reflected by the phrases 'parts of...body moving towards the same spot' and 'music flowing through the soft calipers.' Both the authors have excellently employed 'imagery' to provide a sensory experience to the readers how the human body is being dislocated by the external forces.
