Official Explanation
Sleep is important, or relevant, to your daily life, making “pertinent” the best word for the first blank. The explanation in general may be “mysterious” or “obscure,” but the topic is not “mysterious” or “obscure” “to our daily lives.” Regarding the second blank, the expression “at once fascinating and _________” indicates at least a loose contrast, so you need something that could contrast with “fascinating.” The clue “so ignorant” is a good indication that what you want is “deeply humbling.” Don’t fall for the trap answer “fully impenetrable.” While the topic of sleep is presented as somewhat impenetrable (that is, hard to understand), the blank is not describing sleep, but rather human ignorance about it. “Totally blatant,” which means obvious or not at all hidden, doesn’t describe human ignorance about sleep either.
Answer: C,D
