How did Pi's father help the rhino at the zoo who was suffering from isolation?

Is there supposed to be a story or something? If not the least I can say is he spent time with the rhino, or got him a new friend

Pi's father was able to determine what animals needed to help them feel comfortable and safe.

Explanation:

the answer is:  

he is voicing feelings shared by all humans regardless of race.

in paul laurence dunbar's poem "we wear the mask," he replicates the words mask and we to emphasize how people in general -not just black americans- hide their true feelings. he suggests the masks cover people's faces and eyes, which are the main parts that display their emotions. he also thinks people's pain conceal behind those masks, so that they cannot see reality and nobody is able to see one another's sorrow.
