Answer:
oral fluency, speed, stress, and pauses.
Explanation:
The answer is the first one.
In "Writers often disavow the notion of a 'literary duty'" the author conveys a somewhat condescending attitude, as if they would always follow this and set aside anyone who said otherwise. This attitude says the author is looking down on them, and that the author believes that many authors do not meet their standards.
Another answer I would consider is "...writers ruined by their shrill commitments." However, there is no context or clear tone. The author could be mournful of the lost potential for all we know.
The sort of search you need to conduct is official research investigation and direct sources of information like federal statistics and non-goverment organizations groups data.
The keywords that might help in the search would be "mental health issues and homeless", "homeless addictions", and "substance disorders and homeless".
Some research has found that is a direct connection between homelesness and substance use disorders.
It is not responsible to call homeless drug addicts, because beyond what you see there could be a life of pain and suffering.
Research states that homelessness is not a permanent condition but a temporary circumstance that should not define poeple's future.
But sometimes, the information that stems from the research indicates that there is a correlation between substance abuse and people becoming homeless.
