Answer:
The director's gestures and expressions reveal that the motivation to change the girls' names is to convert the whole world to English standards, even if it has to suppress the culture and individuality of the natives.
Explanation:
This question is related to the short story "By Any Other Name", where the author shows how colonialism sought to suppress the natuvian culture and natural customs, going so far as to modify their identities and personalities. The author shows this, narrating the exchange of names of the girls Premila and Santha, to common Anglo-Saxon names.
The intention of doing this is to show the superiority of English culture and to show the great desire that the English had to take over the world at their leisure. This intention is well explained in the expressions and gestures of the headmistress, who is the person responsible for changing the girls' names.
