Final answer:
The question appears to be based on a misunderstanding, as the provided text discusses the Thesmophoria, a festival for married women in honor of Demeter, with no mention of a baby contest at such a celebration. The Thors'day Thursday Celebration is not historically documented in reference to Thesmophoria.
Step-by-step explanation:
The question about what contest they had for babies at the Thors'day Thursday Celebration appears to be a misunderstanding or a mix of different cultural events. The provided reference text discusses the Thesmophoria, an ancient Greek festival held in honor of the goddess Demeter and her daughter Persephone. This celebration was exclusively for married women, and there is no mention of a baby contest. The first day of Thesmophoria, called Anodos, involved married women from noble families ascending to the sanctuary of Demeter, where they built booths and stayed during the festival. Notably, this event included a procession with equipment, food, and piglets, not babies. Since the Thors'day Thursday Celebration is not mentioned in the historical text nor typically associated with Thesmophoria, it is likely that the question is based on a fictional or modern adaptation rather than an accurate historical event.
