Solution

The correct answer is f) Both b and d.

Explanation:

b) Sleep deprivation leads to a buildup of adenosine in the brain, particularly in the hippocampus, impairing learning. This is true because adenosine is a byproduct of brain activity, and it accumulates in the brain during wakefulness, promoting sleep. When you're sleep-deprived, adenosine levels can build up, impairing neuronal activity and leading to cognitive deficits like impaired learning.

d) The greater the sleep deficit, the more frequent attention lapses are. This is also true. Sleep deprivation can lead to attention lapses, cognitive slowing, and impaired memory, all of which can affect learning. The more sleep-deprived you are, the more severe these effects can be.
