Answer: I think the answers are 
1. B
2. A
3. B
Explanation: 
For number one, it's probably B  because the term "roil" means to make a liquid turbid or muddy. 
Two is A ( self explanatory, a bad smell only lasts for a little while.)
And three ( I think) is maybe B. A reverie is like a daydream or being in the state of having pleasant thoughts and dreaming about being a movie star seems slightly more pleasant than being chased by a monster.
I hope this helps you! ^^
