Answer: a)"This means that we are active during the day and sleep at night."
Explanation:
The text mentions that human beings are diurnal creatures which means that we prefer to be active during the day and then sleep at night.
In Alaska, the winters can be dark for a long period of time such that some areas like Barrow may not see the sun for some months. What this means therefore, is that since humans prefer to sleep during the night, they will be sleeping more in Alaska where it is dark for longer in winter.
