What does the metaphorical tittle suggest about william's cultural identity on ethnic hash

The metaphorical title suggests that Williams has a vast mix of ethnicities in his composition. She uses food to show how she can try different things and like them all, exploring them in the most beneficial way possible.

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.

yes, it can be both.
