Some researchers have suggested that our 24-hour sleep/wake cycle may partially be a response to a world where the sun rises and sets on a 24-hour cycle. Imagine that the earth is gradually speeding up, and in 10,000 years the sun rises and sets on a 22-hour cycle instead. Which of the following would be similar to the sleep patterns of humans in that future world?

If the sun rises and sets on a 22-hour cycle, it would make sense for our sleep patterns to also adjust to this new cycle. This would mean that people would fall asleep once every 22 hours in order to align their sleep with the new cycle of day and night. Option A is unlikely as some form of sleep pattern would still occur. Option B and D do not align with the changes in the length of the day, therefore option C is the best answer.
