Answer:
Correct answer is aesthetics
Step-by-step explanation:
Authenticity is the quality of being realistic, true and genuine. - The very mention of breaking a sequence of events denies authenticity, because if we break the events into parts, we can create false reality, which is not authentic.
Universality is something that is experienced by everyone or everywhere or that is applicable to all kinds of situations. - While it is true that paragraph mentions that everyone is "hyper-alert", the sensation that this paragraph creates is much stronger than just universality. It appeals to our senses and feelings.
Subject matter is a topic dealt with or the subject represented in a debate, exposition, or work of art. - There is no special subject mentioned in the paragraph.
A esthetics is the quality that is connected to beauty and how the mind and emotions react to it. - As previously mentioned, this paragraph puts accent on out emotions and that is why aesthetics is the most important part of it.
