Final answer:
The assertion that Betty Boop was created as a mother-like character who sat in a rocking chair is false; Betty Boop was a flapper-style character with a carefree persona.
Step-by-step explanation:
The statement that Max created Betty Boop to be a solid, calming mother-like character who was generally in a rocking chair observing the action is false. Betty Boop was actually created by Max Fleischer and designed by Grim Natwick. She first appeared in the 1930 cartoon 'Dizzy Dishes.' Betty Boop was known for her flapper-style persona, complete independence, and sexual undertones, which made her a hit during the Jazz Age and the Depression era. She was not a motherly figure sitting in a rocking chair, but rather, a symbol of the carefree and spirited aspects of the Roaring Twenties.
