What is most likely the author's intent by not stating which character is saying from A Wrinkle In Time chapter 7 from the text Once ten is ten. Once eleven is eleven. Once twelve is twelve.?

The author's intention by not stating which character is speaking in the text "Once ten is ten. Once eleven is eleven. Once twelve is twelve." is to create an air of mystery and ambiguity. This allows readers to interpret the Words in a more abstract or symbolic way, rather than being limited by a specific character's perspective.
