But ________ we spend a third of our lives sleeping, it seems that...

• A. Like
• B. Although
• C. There
• D. When

Answer: (B)

This question tests choosing a word that introduces a contrast or concession. Although is used to acknowledge a fact and then present something that contrasts with it. Here, claiming that we spend a third of our lives sleeping is a fact, but the speaker’s observation that follows (“it seems that…”) signals a contrast to that fact. So the sentence reads smoothly as: But although we spend a third of our lives sleeping, it seems that... The other options don’t express the needed contrast: like is for comparisons, there is or there are refers to existence or location, and when signals time.
