I want to know the answer to the following question:
What can even translations completely done by a human still be prone to?
All the background I'm provided with is that "It is certainly true that even purely human-generated translations are prone to error; therefore, to ensure that a machine-generated translation will be useful to a human being and that publishable-quality translation is achieved, such translations must be reviewed and edited by a human.". Is that enough to answer the question?
Answer: yes
