Final answer:
Naomi's silence and willingness to please provide Old Man Gower with a compliant presence that allows him to exercise his will more freely.
Step-by-step explanation:
Naomi’s silence and disposition to please adults can be beneficial to Old Man Gower as it makes her an unassuming and compliant presence in his life. This pliability and desire to not cause trouble or discord would make it easier for Old Man Gower to carry on with his desires and plans without opposition or judgment. In literary narratives, characters who are silent or eager to please often allow other characters, particularly those with more power or dominance like Old Man Gower, to exercise their will more freely.
