• "Vigilant" means watchful. If one is sleepy (due to the drug), it's hard to remain watchful (vigilant) against mistakes.

For question 2:

For question 3:

• "Somnolent" means sleepy. Sandra's already sleepy (somnolent) mind.
• "Languid" means slow and relaxed. The slow (languid) motion of the boat made her sleepier.
