The series is an example of how animators specialized in certain sequences and contributed to character development in storytelling.
Step-by-step explanation:
The statement that Disney animators developed special niches for drawing certain sequences, such as dances, and that their characters began to have personality, with The Three Little Pigs serving as a great example of personality in Disney's Silly Symphonies cartoon series, is true. This series marked a significant step in the evolution of animation, where characters were developed with distinct personalities and traits.
