C1.1 What is the author’s main reason for writing the article? [for example, to recommend improvements, to solve a problem, check an existing theory, etc.]
The author’s main reason for writing the article was to recommend improvements to be taken by drivers to ensure they are safe. The article explores the effects of poor sleep and occupational demands on driving safety in medical residents. The research was done to examine the habits of individuals which influence their perception, nature of behavior and different interactions. Additionally, the author intends to enlighten people on improving human factors and related issues. The author emphasizes on improving human-vehicle and environment interaction through incorporation of the new technology. The author also focuses on the essence of improving sleep quality and sleep quantity in medical residents to ensure driving safety.
C1.2 What do you think is the most important fact(s) or information in the article?
The effect of occupational demands is evident and it affects the psychophysiological component in the medical residents. It also requires additional research to be done to establish the exact contributive factors that affect driving safety.
Stress and sleep negatively affected medical residents driving after duty. Long-term occupation contexts may also be affected by the occupational demands. According to the article’s discussion, improving sleep results to improved driving outcomes.
C1.3 What does the author show in the article? [results/conclusions] 
The author shows that fixed effects linked to linear regression were observed after adjustments were made and they proved that medical residents displayed riskier behaviors in driving by their significant high speeds exceeding the average limit during post duty compared to pre duty.
Logistics regressions indicated that the odds of obtaining lesser sleep were associated with safe driving outcomes was higher on a night workday than a day off.
The author concludes the article by emphasizing on the understanding how high job strain should be mitigated through improving sleep quality. This results to reduction of stress and thus reduces the occurrences of poor driving in medical residents.
C2. 1. Has the article given you enough information or facts to help you with your research?
Give five facts 
Medical residents displayed high levels of stress and experienced poor sleep outcomes throughout the medical residency.
The results of the research proved that medical residents displayed higher levels of stress after duty. It was indicated by their faster driving speeds.
Understanding how to mitigate high job strain may have several implications on the sleep quality.
The comparison of pre-duty, post duty, on-duty and off duty interactions is essential for understanding the psychophysiological factors influencing driving in medical residents.
Improving sleep quality and quantity can improve the driving outcomes in medical residents.
