Answer:
The poems written on the walls of Angel Island were hard to see because they were burned, the facilities was given to war soldiers, and the walls were painted again.
Explanation:
'The Writing on the Wall' is written by Camille T. Dungy. In her essay, Dungy writes about the Asian immigrants who were restricted by the US between 1882 and 1943.
She writes that those immigrants who were having health issues or any other irregularities were send to the Angel Island, where a detention center was build for them. The Angel Island was situated in the middle of the Bay.
These immigrants began writing poems on the walls which became hard to read now because the walls were burned in a fire in the 1940s. After that the station was handed over to the army for war purposes. After the armies left the station, walls of the station were repainted. These factors made it difficult the poems inscribed on the walls hard to read.
