What are the answer choices?
lol
Imagery is when a sentence has descriptive details that help you see what the author wrote.
Example: The frail girl crept through the dark, dusty hallway. Her bare feet blue from the cold, stone floors.
so i would say that the sentence you provided was using imagery :)
I would say definitely use your time wisely. Make sure you are fully focused too. Though it may be difficult to focus, (I understand) try and find some outside resources that can help you bring interest into what you're learning in any subject.
