Final answer:
Funerals for ancient kings were major events that demonstrated the deceased's power and wealth, possibly leading to popularity for those orchestrating them. The inclusion of grave goods and human sacrifices were part of these elaborate funerary practices.
Step-by-step explanation:
It seems that there is no direct information regarding how an undertaker specifically increases popularity or satisfies funeral attendees' curiosity based on the provided context.
However, historical funerals, especially those of ancient kings, were indeed significant social and political events. Elaborate funerals demonstrated the wealth and power of the deceased or their successor.
Moreover, they could have been perceived as a form of "political theatre” and in some cultures were accompanied by human sacrifices as part of the burial goods.
For instance, in the case of Lady Hao or Fu Hao, the royal tombs contained a wealth of grave goods and the fact that these were left undisturbed for archaeologists to find, suggests a high level of respect for the burial traditions and beliefs of the time.
These practices likely satisfied the curiosity of attendees and reinforced the deceased’s importance, possibly making the undertaker or those who orchestrated such funerals 'popular' or respected for managing such complex and significant events.
